The nature of the advantages of magnetic particles, they can be polarized magnetic north or South Pole, the correct polarity when enough magnetic field, hard disk drives can alternately or exchange the hard drive can be stored in the same sequence to the polarization requirements, they represent the data stored in the magnetic recording medium disk of particles bits. Hard drive off, they contain two intersecting tracks and sectors slices. Its purpose is to provide a logical data structure, provides a way to distinguish between the data area. In each track, there are some departments. It is in these sectors hard disk to store data.

 

Hard drive platters coated with magnetic paint mainly sensitive to charged particles or tape as a whole, can be called recording media applications. These magnetic particles can be aligned so that they represent binary numbers, the electromagnetic field induced by the internal hard disk drives they are read / write heads. Recording media is very close watch tiny metal shavings like billions of microscopic particles. When the hard disk drive records data into medium-term, it needs of hundreds of these magnetic sensitive particles (usually anywhere from 500 to 100) to store a single binary digit. Record data necessary to reduce the increase in the number of particles is very limited read / write head of the tiny devices, read and record to record data on the media's accuracy, because the magnetic field for the drive's read / write head read and / or record (write) data is such that it has near the border of the initial data.

 

Should shrink further in an attempt to improve the accuracy of the data will greatly increase the possibility of damage. The research continues to be much smaller or even a single particle for some time now to find a viable solution, the data records. Hard drive may be recorded to the hard drive data, by applying a sufficient magnetic recording medium portion (ie, after a pause, hard disc) of data (a series and / or zero, corresponding to the media stored information) recorded specific particles, by adjusting the required pole (North or South).

In XP and Vista it's effortless to defragment a drive, requiring only numerous mouse button clicks, however most customers allow weeks go by devoid of executing it. They wait around right up until their equipment have slowed to some crawl earlier to executing this most basic work of pc maintenance.

 

Another cause may be the quantity of information saved there. The whole great offer more information inside computer hardware, the slower retrieval and write-to prices become. The remedy is obvious. Both do a tad of home cleaning, removing unneeded files, or include one more drive.

Sometimes, a sluggish challenging generate may be considered a warning sign of spyware, adware, and even a virus. A fantastic protection plan can scan your drive, and inform you if you actually possess just one of those problems.

Advantages & Disadvantages Of Tablet PC's

The tablet computer market brings a vast sea of things to people and it is commonly believed that not all things are perfect. As the old saying goes "every coin has two sides" and there is no exception for tablet computers.

Advantages
The greatest advantage of Book PCs is their mobility. Small and light, the book pc allows you to plan in any situation. All book pc's allotment one affair in common, they use blow awning technology to acquiesce you to ascribe abstracts on the actual awning you are alive on. This is why these machines are so small; in book approach you allocate with the keyboard and instead blazon on a basic keyboard or handwrite with a stylus.

Another advantage of Book pc is that they can be acclimated for hard disk drives and analogy with the aid of a stylus. This allows for an added artistic and free-flowing alternation with the agenda paper. For example, it is pretty obvious that touch awning technology has avant-garde abundantly over endure few years with the accession of the stylish band.

 

Moreover, the previous thing has percolated throughout the absolute industry to advice actualize an accomplished new bearing of accessories that are easier to use and avowal an added user experience. With the boundless acceptance of this technology, the prices for internal hard disk drives has also alone rapidly and for the aboriginal time ever, this technology can be acquired for the aforementioned amount as a accepted mid-level laptop.

Disadvantages
While these machines are much more portable than their desktop & laptop ancestors, they do tend to be added than the slate appearance book as they crave added processor, cartoon and harder drive space. However, newer models such as the Dell Duo action netbook sized accretion with the allowances of blow awning book account while still accepting the ability of a mid-level laptop.

 

Some of the earlier convertible book pc accepts an anachronous blow awning which can be apathetic or can alone be acclimated with a stylus. This will absolutely accomplish them harder to use and the admittance of feel blow awning adequacy would be bigger on any convertible laptop you are because acquiring.

Over the endure few months we accept apparent the gap abutting with the absolution of the Dell Inspiron Duo and some of the big-ticket top akin Hewlett Packard machines advancing actual abutting indeed.

In a nutshell, whatever the computer you choose and whatever style of the computer is, pay attention to both advantages and disadvantages of the computer and ensure that lest you can endure the shortcomings, or you'd better not purchase it.

Why use a Storage Flash Drive as a Backup Tool

Why use a Storage Flash Drive as a Backup Tool?

Everyone knows you should back up your files. Not everyone does it. I know this by personal experience, having just lost the use of my laptop. Although the hard drive was not the culprit, the repair process is sure to cause me loss of all my files on that laptop. The good news for me is that there was nothing there I did not have duplicated elsewhere. But there could have been. If I had been diligent as I know I should, the files on that laptop would have regularly backed up and I would not have had a moments worry about loss.

Here is where a USB flash drive would have come in handy. Storage Flash Drives have easy drag and drop capabilities as backups. Capacities range from a few hundred megabytes to tens of gigabytes. Flash drives are even better than CDs for this purpose because they create files faster and are much more flexible for updating files. CDs largely are a burn once instrument, whereas a flash drive can be updated thousands of times at least.

You do not need to backup all the files on your drive. Programs can be reinstalled. Many times data files produced by those programs would be difficult or impossible to recreate. So backup those files you have created (letters,artwork,even emails) and call it a day. It is helpful if you note where those files need to go in the reinstalled programs.

I know that I for one am going to get a large capacity usb thumb drive to use as a backup tool. I have learned first hand how quickly a computer can go south and how important it is to back up important and sometimes irreplaceable files regularly.

Flash to the future - The next generation of non-volatile memory

Flash to the future - The next generation of non-volatile memory

Quickly, name a gadget that didn’t even exist in the year 2000 but has since transformed our culture and the way we live today. 99% of you probably answered with MP3 player, tablet computer, GPS, e-Reader or smart phone. What do all of these devices have in common? For one thing, they are all super portable, and that feature is due to the unbridled success of Flash memory.

The development and maturation of NAND Flash as an affordable, non-volatile, solid-state data storage solution has helped usher in an era of mobile technology. It has allowed us to invent gadgets that simply would not have worked if incorporated with spinning platter drives.

However, after a decade of revolutionizing the technology industry, Flash is reaching its limits for further development. In order to increase Flash’s maximum capacity manufacturers have been shrinking the distance between transistors on flash chips over the years. In 2000 Flash technology was manufactured using a 180-nanometer process. Today, modern NAND Flash cells are for the most part manufactured using a 32nm process, with some bleeding-edge manufacturers moving to a 24nm process. The only issue with this is that as Flash continues to shrink it becomes less and less reliable. As of April 2011, the theoretical minimum Flash cell size is 19nm. Beyond that point, the stability of Flash becomes highly suspect.

As we approach the limit of Flash technology, it is prudent to look towards the future and consider a couple of promising non-volatile, solid-state storage technologies that may succeed Flash memory in our mobile devices.

Phase-change memory

Like Flash, Phase-change memory (aka PRAM or PCM) is non-volatile, solid-state computer memory; meaning that it retains information when powered off and has no moving parts. Unlike Flash which works by changing the electronic charge stored within gates to set a bit as a 1 or 0, PCM uses an electric current to produce heat which switches a chalcogenide glass between crystalline and amorphous states to set a bit as a 1 or 0.

PCM has several significant advantages over Flash.

-          PCM can effectively write data 30x faster. The memory element can change the state of a single bit from a 1 to 0.  In Flash if a bit is set to 0, the only way it can be changed to a 1 is by erasing an entire block of bits.

-          PCM can be scaled to 0.0467 nanometers without any loss of reliability.

-          PCM is more durable than Flash. Flash cells degrade quickly because the burst of voltage across the cell causes degradation. Once cells begin degrading, they leak electric charge causing corruption and loss of data. Flash memory is rated for about 5000 writes per sector, and most devices employ wear leveling to make them stable up to 1 million write cycles. PCM also degrades with use due to thermal expansion and metal migration but at a much slower rate. Theoretically PCM should endure up to 100 million write cycles.

-          PCM is suitable for use in more environments than Flash. Because Flash relies on trapped electrons to store information, it is susceptible to data corruption due to exposure to radiation. PCM exhibits a higher resistance to radiation and therefore can be used in space and military applications.

Magnetoresistive RAM

Magentoresistive RAM (aka MRAM) is another non-volatile, solid state technology has been in development since the mid 1990s. MRAM stores data using magnetic charge as opposed to electrical charge. MRAM is composed of pairs of miniscule ferromagnetic plates which make up the memory cells. Each cell consists of two magnetic layers separated by an insulating layer. Each cell can be manipulated by an induced magnetic field which sets the polarity of the magnetic layers in parallel orientation or in an anti-parallel orientation. The different orientations determine whether the bit is set to a 1 or a 0.

MRAM has many significant advantages over Flash and PCM:

-          MRAM can be read and written to faster, and can be done on a much smaller scale. Like PCM, single bits can be changed from 1 to 0 without having to erase an entire block.

-          MRAM degrades substantially slower than either Flash or PCM.

-          MRAM could replace all memory in the future, making it a universal storage technology. It should offer speeds close to that of SRAM, with densities approaching that of DRAM, while being able to store information when power is removed like Flash or EEPROM.

-          Like PCM, MRAM also exhibits a higher resistance to radiation and therefore can be used in space and military applications that Flash is not suited for.

Final Thoughts

It should be noted that we can only speculate on when manufacturers will have to stop using Flash as the primary storage media in their products. Consider that in 2002, many experts assumed that Flash cells would not be stable when scaled past 45nm and predicted that Flash technology would need to be replaced by 2010. We know now that those predictions proved to be false.

Many experts today believe that technological breakthroughs, like implementing graphene, will allow the technology to be scaled down to 10nm without loss of stability. If this is true, Flash may still be the dominant memory in mobile devices for many years to come. Even though emerging technologies like PCM or MRAM are vastly superior to Flash in many ways, PCM and MRAM are much more expensive to manufacture than Flash. As long as Flash can remain a viable storage media there are too few incentives, and too much production costs for manufacturers to rush devices that use next generation memory into the market.

Beginners Guide to Recovering Data From a Crashed Hard Drive

Beginners Guide to Recovering Data From a Crashed Hard Drive
A beginners guide and first steps to recover data from a failed hard drive

A failed hard drive can be a painful experience for any normal user as it technically means that years of hard work, important data and personal information gone forever. The good news is that data is recoverable in most cases depending upon the nature of the damage to the hard drive. This article aims to provide first steps to the user to determine the level of damage and to take informed decisions for recovering the information from the failed drive.

  • First Steps- Relax, make sure not to overheat your “hard drive” and convince yourselves that “hard drives fail and you can recover data from them”
  • Determine the nature of failure- Hard drive failures can be classified into these broad parameters
  1. Wrong Diagnosis- Chances are bright that the failure (generally like boot failures) are not inherently disk failures but to do with other problems in your system. Best way to determine the same is taking out the drive and connecting the same with an USB as a secondary drive in a “healthy” laptop or system and check the same. If you HD is ok you should be able to operate it without any glitches. (safe to back it up at this stage)
  2. Logical Failure- There is no physical damage to the drive and the error is primarily attributed to maybe a corrupt file system or wrong formatting. It is advisable to try to give it a hand yourself to recover the data if it is only a logical failure, there are numerous softwares available to heal your drive and will cost you far less than sending your drive to the “surgeon” . Most of the data recovery softwares offer a free demo which should give you a fair idea of the recoverability. Also, it is common for these softwares to recover data and store the same in a different fashion i.e. all files of a particular extension in a single location and may take insane amounts of time.
  3. Mechanical Failure- This means one of your physical hard drive components is damaged. It is advisable to send it to the pros if is a clear case of mechanical failure as chances are bright that a whole bulk of data is recoverable by them. It may set you back a few hundreds or thousands of dollars depending upon your configuration and brand.

Now that the overall first steps of the diagnostic and recovery processes are clear, make a coffee for yourself and start out to salvage your precious data.

Securing Flash Drives within the Enterprise

Securing Flash Drives within the Enterprise

Flash drives have revolutionized the business world with their convenience and portability; however, for infosec professionals, flash drives are a dual edged sword.  Their tiny size often makes them easy to lose and their storage capacity allows massive amounts of potentially sensitive data to be stored and transported on them.

If lost or stolen, a single unencrypted flash drive has the potential to cause a massive data breach.

So how can infosec professionals deal with flash drives?

Ban them and there is the risk that productivity will suffer.  Business professionals utilize flash drives constantly for sales data, customer presentations, marketing and more.  But if they are allowed without having some sort of management plan in place they pose a very real security threat.  So, can thumb drives be managed without severely limiting their functionality and convenience?

The answer to this will vary greatly depending on your organizational policies and security standards; however, there are options for using flash drives securely.

Security Policy

The starting point should be a well written and detailed security policy; one that is explained and made accessible to all employees (for more on this, check out this article).  Clearly communicating the policy to employees and providing training is essential since they are the ones who will be carrying out and following the guidelines.  The security policy should clearly outline secure flash drive protocol and acceptable security standards (i.e. - whether BYOD is acceptable, encryption mandates, password strength, etc.).

Another point on security policies:  Review them frequently.  Technology changes quickly, so a review of your policy should be a regular occurrence.  After the review, update what needs to be updated, redistribute to your users and retrain if necessary, then schedule another review down the road.

Endpoint Security

Once you have a good security policy in place, you need a way to enforce some of the rules outlined within it.  One of the best ways is with an endpoint security application.  Endpoint security applications are available through a variety of vendors and come in a wide variety of configurations and prices.  From simple USB device control to full system control, the choice will depend on your budget and needs.

You should create a whitelist (or blacklist) methodology for allowing or disallowing certain flash drives and users.  Set restrictions on what data they can and cannot access and track data access and IP range.  Some secure flash drive manufacturers can burn custom identifiers into their flash drives, allowing you to pair a memory stick to a user.  This allows for easier tracking of exactly who is accessing what.

Remote Management

Remote management is a relatively new, but very powerful, feature for securing USB Flash Drives.  Paired with endpoint security, it allows for a wider range of administrator control than using endpoint security alone.  If you have a lost or stolen flash drive, remote management applications such as Kanguru Solutions Kanguru Remote Management Console (KRMC) allows you to remotely erase it, negating any possible data breach.  In addition, Kanguru’s remote management application allows for controlling password strength, invalid login attempts, IP ranges and more.

Encrypted Flash Drives

It should be a requirement that any thumb drives used within an organization be encrypted.  Encryption is relatively easy to use and administer and it doesn’t put a major damper on productivity either, so there no excuse for not using it.  Devices with a high level of hardware encryption are preferred.  Hardware encrypted flash drives have the least effect on performance and tend to be more secure than software encrypted flash drives.

Another option to consider is organization owned devices.  By requiring employees to use company owned memory sticks with a lock down configuration it allows administrators to setup policies that can’t be tampered with by individual users.

Some other options to consider are encrypted thumb drives with built-in anti-virus, tamper resistant design and drives that can limit the number of invalid login attempts.  These are useful for preventing malware and also brute force attacks should someone without authorization attempt to access the device.

With the right combination of security policy, management tools and encryption, flash drives can be used in a safe, effective manner.

USB Storage Flash Drives. Need one

USB Storage Flash Drives. Need one?

In today’s computer oriented society, information, and lots of it, is key. Each of us creates and are accountable for mass amounts of information just in the course of our everyday lives. Just think of the number of passwords you have to keep track of to conduct normal business.

One of the hottest sectors in information storage is the USB Flash Drive. They have only been around a few years but the jump in capacity and reductions in price have been amazing. No longer do we have to carry a stack of floppy disks or even CDs. Large amounts of data can be stored in devices smaller in most cases than a penknife. These storage flash drives come in sizes from 256mb to 32gb. Even larger sizes are on the horizon.

But how can they be used,and do you need one?

They are commonly used by students these days to carry term papers,class files and research around campus. Information on these drives can be exchanged between computers and students. Even music and video files are easily stored and accessed with these drives.

USB storage flash drives are also increasingly used in business. Customer files can be easily transferred between work and home computers. Companies are even branding drives with their logo and including sales information in special sectors on the drive.

Lots of hospitals use these drives now to store patient information around the hospital. The drives can be fastened to keychains or lanyards for increased security. As many as 12,000 patient files are at doctor or nurse fingers quicky and reliably.

These are just a few of the groups who are beginning to regularly use USB drives in their everyday practices. Maybe you are among them or maybe you are among the countless other industries just beginning to find the usefulness of the drives.

Do you need one? If you do not use computers daily, probably not. But if like me you find yourself in front of a screen most every day, I’d get at least one.

How to Optimize Your Computer for Maximum Speed and Uptime

How to Optimize Your Computer for Maximum Speed and Uptime
hese easy steps show how adjusting basic settings can ensure any Windows PC or notebook not only runs quicker, but also is protected from crashes and potential data loss

Often a computer will start out life blazingly quick and stable, but over time deteriorates into a frustratingly slow machine, with system freezes, crashing, and constant error messages. These problems can likely be fixed by applying simple Windows settings changes, performing routine maintenance, and following some basic rules and suggestions endorsed by the creators of Windows themselves,Microsoft.

Free Up & Clean Hard Drive Space

Allowing the primary hard drive to become over 90% full can seriously affect performance, cause crashes, instability, result in data loss or complete system failure. Microsoft recommend using Windows' Disk Cleanup regularly to delete files you don’t need, keep your recycle bin empty, and generally hoover away digital debris. Invest in an external drive to save videos, music, photos etc. or other large files which are not needed daily.

Programs that were installed but never used are speed bumps on the performance highway, and eat up valuable hard drive and RAM space - according to Microsoft, one should visit Windows' Control Panel and remove them! Also, look for the folder they were installed to on the hard drive, as well as any icons or start menus they may have created, and delete them too. It’s good to perform a restart after any uninstall to “reset” the system and check that all is well.

Once this is done, give the hard drive a shot in the arm; running Disk Checker performs a health check of the hard drive to make sure it doesn’t have any potential problems which could cause slowdown or potential disk failure. Run the full surface scan option sometimes as well, which can take an hour or more, but looks deeper for hard drive problems. If Disk Checker reports back with serious issues, it’s time to consider replacement.

Lastly, improve hard drive access speed by tidying up the way it stores the thousands of files you store on it. Do this by running Windows Disk Defragmenter once a week, which sorts out all files into neat categories so that it can access and dish them up quicker.

Maximize Random Access Memory (RAM)

Random Access Memory (RAM) is the lifeblood of a fast computer. Every application and task uses some of your computer's RAM, so it is important to keep as much of it free and available at all times.

For starters, running 22 programs at once might look super productive, but no one would feel that way living with snail-paced performace. Close open programs that aren’t needed, which frees up RAM for speeding up the programs actually being used.

High resolution wallpapers, dancing cursors, funky noises and animated icons are really great... at eating RAM. Change the Windows theme to something less flashy, and use a low resolution background picture, or none at all, to free up some memory.

Next, desktop icons and tray icons each use a little bit of RAM even while sitting dormant on your desktop or menu bar, both during computer startup and while using the machine. Try deleting whatever icons and shortcuts you don't need, or use one or the other of each (desktop shortcuts or tray icons, not both) to save some resources.

Microsoft Windows Vista and Windows 7 can use some flash drives or memory cards as “removable RAM”. Insert the USB drive, right click to bring up its properties, and dedicate all or part of it to “ReadyBoost”, which can help speed things up. If you can, format the drive completely using its default settings (wipes all data), and dedicate the entire drive capacity to ReadyBoost, and leave it permanently in the USB port.

Finally, adding RAM memory to any machine is still the most effective way to speed up any computer, as long as you haven't exhausted this option already. A rule of thumb is that the speed of the CPU should at least be matched by the gigabytes of installed RAM.

General PC Tweaks, Updates and Speed Recommendations

Some programs, when installed, place themselves in Window’s startup folder. This means they will run every time the machine is booted up, which lengthens the start process and eats precious memory while running in the background.

If a program doesn't need to start every time the machine is booted, delete it from the “Startup” folder in the Windows program list (this does not ninstall or delete the program), and rather run it from the Start bar when needed. For more advanced options, you can completely customize a selective startup list for your computer.

To work efficiently and maximise performance, every hardware component of a computer needs drivers – and like their namesake, good ones get you where you need faster than the bad ones. Run Windows Update to check for updated drivers, and visit the websites of the hardware vendors, to download the latest drivers or repair damaged drivers. This applies especially to graphics cards and system mainboards.

Next, always have decent, regularly updated antivirus and spyware software running on your system. Without it, browsing the web opens it up to having nasty leeches, viruses and trojans, slowing it down and affecting its overall health.

Finally, by parting with a little cash, there are some good software tools that make speeding up any computer a doddle, and also ensure it stays that way in future with proactive maintenance scheduling. Many also have built-in fail-safes, in case something important gets knackered while adjusting the settings. This may be the way to go for inexperienced users, as an all-in-one solution for all the above tips, and more.

Tips on Maintaining the Hard Disk Drive

When it comes to the problem of a hard disk drive, most people would like to buy another one to replace it rather than maintain it. To be honest, it is really not a good choice as hard disk drives may waste your money and make lead to the loss of your data. Thus, maintaining your hard disk should be the most effective way. In the following parts, I would like to give you some tips on maintaining your computer hard disk drive.
Tip 1: make use of your disk cleanup. A disk cleanup can remove the unwanted files and free up space on the hard disk. With it, you can remove temporary Internet files as well as downloaded program files, including ActiveX controls and Java applets, temporary Windows files and empty the Recycle Bin. In addition, it also deletes optional Windows components that you are not using and installed programs that you no longer use. For this reason, it is also called the cleaner of computers.

 

Do you know how to use the Disk Cleanup tool in Windows XP? First of all, you need to launch Disk Cleanup click Start, then choose all Programs, you will find Accessories there, including System Tools, entertainment and so on. Then click System Tools. After that, you will find a dialogue window which will allow you to select the drive you want to clean up. What you need to do is to select the drive and click OK. Now the Disk Cleanup tool will examine the drive and determine the amount of space that can potentially be freed up. Then you will get the result which files could be deleted and what amount of space could be emptied as long as internal hard disk drives is done.

 

Tip 2: check for hard disk errors. For people who are not familiar with their computer, they can sue Chkdsk.exe command, which verifies the logical integrity of a file system. Once there are some logical inconsistencies in the hard drive, it takes the required actions and repairs the file system data. How to launch disk error checking? You can double-click My Computer and right-click the hard disk drive that you want to check for errors and select properties. Then you need to choose the Tools tab and click check now option. You will find a dialogue box which opens up showing the Check disk options, and then you just need to select the options as appropriate and click Start.
Tip 3: take advantage of disk defragments. Using the disk defragment can help to keep the hard disk in good health. You can click on the particular drive and click properties, and then go to tools tab and choose Defragment Now.
Just keeping the above tips on mind, then you will find that maintain your computer hard disk drive can bring a lot of achievement for you!

Why Is Your Hard Drive So Important

Why Is Your Hard Drive So Important?

A Computer Components That You Never Ignore

From cheap used laptops. The title says it all. Although, some would argue that the processor is the most important part of the Personal Computer but still how you can use it without an application stored in the hard drive. Let’s just say that everything is equally important. Without the processor, the hard drive would be useless and without the RAM everything else won’t just work. But taking care of your hard drive is also a very important responsibility.

When you first install your hard drive, the manufacturers have their own specific tools before you install any applications. You can go to the manufacturer website and get the tools you need and you might also see some useful instructions there to improve the functionality of the Components or how to ensure that the hard drive will work well.

It is also not recommended to install your hard drive in a hot environment. Keep your hard drive cool at all times. As you use the PC component, it produces heat. And in the long run if you disregard the heat it will affect the performance of the hard drive and eventually if left unchecked could serious damage to the Parts.

To make sure that your hard drive is functioning okay, do not drop or shake the hard drive while the Personal Computer is still on. So this means you have to be careful moving the Computer or subjecting it to vibrations. The same is true with your laptop so you should be careful. But to avoid any inconvenience in the future, make sure that you regularly back up your files in your hard drive. You can backup in flash drives, DVDs or in external hard drives. But in case the worse indeed happen, there are recovery software that you could use to get those files lost in case your hard drive failed without you having backed up anything.

Once you have your hard drive going, you need to take better care for it on the digital file side. Learn to organize your files to avoid any file corruption. The damaged files could affect your Parts by created bad sectors. Also, it would be great to have an anti-virus scanner installed so you can avoid file infections which can be potentially dangerous to the integrity of your hard drive. Aside from corruption of files, sudden interruption of even simple processes like transferring of files can affect the physical health of your hard drive. The same can be said when power was suddenly cut during processing or when you were using an application. The software could become corrupted and that could be transferred as physical damage on the hard drive.

How do I put a password on my USB flash drive (thumb drive) storage device

How do I put a password on my USB flash drive (thumb drive) storage device? I just want a way to carry my files with me (on my key chain) but make sure that, if I lose the drive, no one else can access those files. Thus, I wouldn't mind putting a password on a folder and then putting all of my files into one folder inside the drive. I guess I could put a password on each individual file, but that seems like a lot of trouble.

Some USB thumb drive do not have a security feature mentioned, but if you do have it click on my computer, then click on the name of your thumb drive, the folder will open, when you see a icon folder that represent your security folder click on it and then follow instructions.

Hard Disk Errors Are You Responsible

Hard Disk Errors: Are You Responsible?
A mobile computer's hard drive is most vulnerable to movement during the power-down sequence. Use the sleep mode to avoid some hard disk problems.

Hard drives store data in files on most computer systems. As Andy Coates (2008) has pointed out, a hard drive contains a rotating platter which has a magnetic coating. Data is stored and retrieved by a read/write head which is positioned over one of the platter's numerous circular tracts. The rotation of the platter positions the appropriate data storage area under the read/write head, and the data is transferred.

Recovering From Read Errors

A Cyclic Redundancy Check (CRC) is stored with every data chunk on the hard disk. A CRC is like a sub-total, a checksum in computer jargon; but the CRC is calculated by a complex formula, which minimizes the chance that multiple errors would allow corrupted data to be accepted. When a read error is encountered, the computer system rereads the data; and most read errors go unnoticed by the user.

Hard Drive Write Errors

If data are incorrectly written to the hard disk, the computer will later refuse to accept the adulterated information. Multiple clicks are often heard as the system attempts to retrieve bad data. A corrupted file cannot be used, but several services are available to help recover the damaged data.

How Do Hard Disk Errors Happen?

If a laptop or notebook is jarred from the side while it is in the act of transferring data to the hard disk, the write head can be displaced onto an adjoining tract (Anonymous, 1994). The drive will continue writing data, but in the wrong place.

If the displacement of the write head occurs over an empty portion of the hard disk, no damage is done. However, if the write head is moved over a previously stored file, the older file is corrupted (Anonymous, 1994). The error may become apparent only when the computer attempts to retrieve the ruined file.

I Don't Whack the Computer When I Press Save!

When a user clicks the save icon or closes an application, the computer writes data to memory rather than to the hard disk. This information is transferred to the disk as time allows; but some data usually needs to be stored when the laptop or notebook is turned off. Consequently, several seconds are needed; and during this short interval, the computer is most vulnerable to hard disk corruption. Once a user has started the power-down sequence, he should not move his computer until that sequence has completed.

But I Have To Move My Laptop/Notebook Right Now!

Emergencies can force a user to relocate his computer. A supervisor says, “Follow me and bring your computer.” A toddler gets into; well, what doesn't a toddler get into? The 30-seconds to let the computer completely power-down is simply not available.

Closing the Lid Options

In Window's Control Panel, the user can select what actions the computer takes when the lid is closed. This writer advises placing the computer into the sleep (not hibernate) mode. The sleep mode is simply a low power state, and nothing is written to the hard drive. The user can select whether a password is required when the computer is brought out of the low-power mode.

In conclusion, some hard disk errors can be avoided by having the computer enter a low-power state when the lid is closed. This allows the computer to be moved quickly and safely. Hard drive errors can also be minimized by making certain that the computer has completed its power-down sequence before it is moved.

Solid-state drive and hard drive which is more popular

With computer technology is always evolving, trends come and go. In the computer age, many people are struggling, the latest and greatest technology will soon be considered the standard. Most computers these days have HDD (hard drive) hard drive, but a new competitor is emerging SSD (solid state drive). Technology is always changing the direction of the flow, it may be more common hard drive with the new SSD. 
Price and storage space

 

Because SSD drives now far less than expensive counterparts. You can buy for about $ 100, 1 TB hard drive. The same $ 100 will only get 64 Gigabyte solid state hard drive. If you want to have a larger SSD than with a huge storage space, you will spend 300-400 U.S. dollars, if not more of a TB's is 10,000 gigabytes.
Reliability and speed of hard disk drives
SSD is considered to be far more than their hard counterparts reliable. This is because the SSD has no moving parts, on the contrary there are many moving mechanical parts. This helps to impact performance. As the most solid state 1500 grams or more units, which means that if you do not accidentally delete your computer or laptop hard drive should be fine. Hard disk drive has a much lower impact ratings. As for the speed of the SSD hard drive kick ass. See themselves, here is how big the difference is really a YouTube video.

 

Now that the hard disk drive type has its own advantages and disadvantages. If you are looking for low-cost drives, there are plenty of storage capacity, hard drive is the way to go. If you do not mind spending the extra money to a lot of speed, solid-state hard drive is your alley. Please make sure your computer needs to consider for your machine before purchasing any hardware, always must be made by a professional installation parts.
Computer technology is always changing, so it is a great idea to keep the current trend. Maintain their own knowledge, is the best way to find your computing needs.
