It is a logical statement that all hard drives fail at some point of time. There are various reasons that account for a dead hard disk. There are two forms of reported hard drive failures, logical and mechanical.
There can be no better cure than prevention, i.e., to backup the data frequently, but in case of a hard drive failure, various hard drive recovery tools help with accessing data from the dead hard disk.
Why do Hard Drive Failures Occur: Logical Errors and Mechanical Failures
An operating system stores data onto logical locations or virtual addresses which are mapped against physical addresses on the hard disks. These mappings are stored in tables by the OS and are accessed when an application requires the tables. Incorrect termination of OS system files or services, viruses, applications not correctly configured, or installation of incompatible software have been reported to make these tables inaccessible by the OS for use, resulting in hard drive failures.
Mechanical or physical failures occur due to overheating of computer parts, voltage inefficiencies, mishandling of the hard drive, a corrupt firmware and media damage owing to overage or environmental conditions.
Data Recovery After Logical Hard Drive Failure
If experiencing any problems with the hard disk such as regular appearance of the BSOD (Blue Screen of Death), extremely slow retrieval of files from hard drive or regular freezing of the computer, it is time to check the hard drive for errors or failures.
The first step is to check if the problem is a logical error or a mechanical failure. Open the BIOS settings of the computer and check for the hard disk being listed there. If you can find your hard disk through BIOS, the problem is most likely a logical error.
Assuming that the hard drive is completely dead (the operating system fails to load), there are a few steps to be followed to recover the data from the logically dead hard drive.
The method being described cannot be guaranteed to work in all conditions since there can be a lot of causes for a dead or failed hard drive.
To recover data from a logical hard drive failure, one needs a working computer. Install the free application PC Inspector File Recovery. Install this freeware on the working hard drive. When you have done this, attach the failed hard drive as a secondary hard disk to the working computer. Once the BIOS detects the failed hard disk, data can most likely be recovered from the dead hard drive.
The freeware comes with a guide which displays the exact procedure to recover data from the failed hard drive. Follow those steps to recover data. If unable to recover data with the help of the above tool, switch to the next procedure.
Data Recovery After Mechanical Hard Drive Failure
In case of a mechanical failure of the hard drive, it is advisable to seek the help of a hard disk data recovery service. Mechanical failures can be found in many ways. If the hard disk is making sounds other than it usually makes accompanied with regular BSOD, frequent OS crashes, freezing of computer, and failure to recover data from a specific location, it is a good enough sign that the hard disk is getting close to a complete mechanical failure.
If the BIOS of the computer fails to show up a hard drive attached, then the most likely reason is a mechanical failure. It is most advisable to contact a hard disk data recovery service to recover the data that has been lost.
