In most cases, the cause is either virus related or due to a corrupted system file.

If the light is flashing but the computer is not booting up, then the problem may be software related. Check whether the flashing light in front of the computer case is blinking or not. To determine whether a hard drive has crashed due to mechanical failure or a software related problem is relatively simple.
Determining the Cause of a Hard Drive Crash These failures are very expensive or impossible to recover. Your data is being scratched right off the surface of the platters! You can often hear this damage occurring. In these cases, the hard drive platters are being scratched. Serious hard drive platter failures can occur as a result of hard drive arm failures. This may, or may not, result in the loss of some data. The hard drive will mark that spot bad and attempt to move the data to a good spot on the hard drive. Sometimes bad spots will develop during the life of the hard drive. Modern hard drives automatically mark those bad spots as unusable and do not store data there. There will always be some bad spots on the platter surface. No drive platter is manufactured perfectly. If the hard drive platters have not been damaged, a data recovery specialist may still be able to recover data from a hard drive with a damaged hard drive arm. When you hear the clicking noises from your hard drive which signal a hard drive arm failure, back up all necessary data immediately and power the system down as soon as possible. When the hard drive arm fails, there is a very good chance that it will damage the hard drive platters. This should be done in a clean-room environment, to prevent dust from damaging the hard drive. In these cases, it is usually possible to take the mechanical parts out of the hard drive assembly and place them into another identical hard drive unit. This can happen, for example, if the hard drive is subject to a power surge or a discharge of static electricity. When a hard drive physically fails, sometimes the mechanical parts of the hard drive remain undamaged. This task may require the services of a data recovery specialist. Software errors usually result from software writing data to the wrong part of the disk.Įrrors caused by software are generally much more difficult for off-the-shelf data recovery software to correct. User errors can sometimes be resolved through the use of off-the-shelf data recovery software. User errors include accidentally deleting or overwriting files and accidentally formatting a or deleting a partition. Here is an overview of some common reasons for a hard drive failure or data loss. Viruses, Spyware, adware, and Trojan horses can also cause system file corruption, resulting in a hard drive crash. Corrupted registry files or system files can also cause hard drive crashes. If the arm fails to function or the motor overheats or stops spinning, there is a chance that the hard drive will crash, rendering data seemingly inaccessible from all hard drive areas. The hard drive is a magnetic disc that spins and has an extended arm that collects data from any area of the hard drive.
#Recover failed hard drive full#
A full blown hard drive crash is generally attributed to a hardware issue. There could be multiple causes for hard drive failures. Whether the hard drive has locked up or has completely crashed, there is a good chance the data can be recovered with a variety of hard drive data recovering techniques. Hard drive data recovery is the process of recovering lost data from a hard drive when the data cannot be readily accessed through normal retrieval methods.
