Disk Drive Failure – What went wrong?
Many things can cause a hard disk drive failure and therefore a data loss. Many things can cause a hard disk drive failure. The most common reason is some type of logical damage, such as deleted or overwritten files.
However, hard disk drive may suffer some type of physical impact damage, such as dropping the device or some other type of physical shock. The hard drive is composed of precise internal components that run at extremely high speeds and are very sensitive to this type of jarring. If you begin to hear any clicking or buzzing sounds after a bump or drop to your device it is extremely important to turn it off immediately. Continuing to work with your equipment can end up causing even more damage to the internal components of your computer.
A logical failure refers to non-physical failure. The problem occurs in the hard drive’s file structure or software rather than the actual hardware. A logical failure can be caused by many different factors, a virus, system driver conflict, human error or a software malfunction can all cause a logical hard drive crash. When this type of failure happens, imaging or cloning the computer will do no good. Do not try to reinstall Windows or run the useless operating system tools like CHKDSK because these tools often make things worse. The good news with a logical failure is that in most cases a hard drive recovery service provider such as My Data Recovery Lab can successfully restore data because there is no damage to the drive’s hardware.
In addition to impact damage other types of physical damage such as water or heat also cause serious threats to internal and external hard drives. Heat damage is often a result of inadequate ventilation. One should take care that the systems fan, usually located on the back or bottom of the computer is never blocked. Hard drive failure as a result of physical damage generally happens quickly and without warning often causing extensive damage to hard drives’ electronic parts, which are not built to withstand either element. The only way to avoid physical damage is to be contentious in the way you care for your computing system.
Firmware is the software program normally only accessible by the disk manufacturers. It is used to do low level disk testing and functions that are directly responsible for the proper functions and healthy state of hard disk. Without the firmware code, no communication will be possible between the PC system and the hard disk. Modern disks normally have their firmware codes located on data platters and also the PCB board. If the firmware area of the platter is corrupted, the drive will appear to have failed even all the electrical and mechanical components are still fully functional.
Mechanical Failures/Head Crash
If any of the hard drive’s mechanical parts fails, the whole drive will fail. The parts operate with incredible precision. Circuit boards, spindle motors, ball bearings – any of these parts are susceptible to failure. The worst type of failure is known as a head crash. In this case, the read/write head drops down directly onto the platter and scrapes away the magnetic material. Unfortunately in cases such as these data is permanently lost. Data on unaffected parts of the platters may be recoverable, but usually data are spread around the platters. This type of failure can be particularly devastating, but if the failure didn’t affect the platters there may be some hope for a recovery. You most certainly will need to consult with a knowledgeable data recovery service provider for this job!
