The hard disk drive or the hard drive for short is a vital component of a computer as it serves as a storage device for all types of media format. As such, it needs to be maintained well and free from viruses to keep it from getting damaged or corrupted. Although data from the hard drive can still be recovered once it encounters problems, not all efforts in data recovery are always successful.

Physical damage

Damage to a hard drive can either be physical or logical. Physical damage refers to a head crash or failed motor in hard drives, scratching off of a CD-ROM's metallic dye layer and breaking of tapes. Data loss often results from physical damage. Sometimes this can also affect the logical structures of the file system.

Physical damage to hard drives needs professional repair. Experts do not recommend end users without thorough technical knowledge and the right hardware to fix the problem themselves as doing so may only cause further damage to the hard disk. Repair of a hard drive is usually done in an ISO-certified cleanroom facility as exposing the disk in a normal environment would make it vulnerable to dust which could settle on the platter and affect the read/write head resulting in new head crashes.

Logical damage

Logical damage to a hard disk, on the other hand, results from power outages. When power failures occur, the file system structures may not be successfully be written to the storage medium. The outcome of this is an inconsistent behavior such as incorrect reporting of a drive's available free space, system crashes and even data loss. Some forms of logical damage, though, can also be mistaken as a physical damage.

There are different programs available that can fix this problem. Some file systems have their own repair toolkit or utility that is used in recovering data. Examples of these are the fsck utility of Linux, the disk utility of Mac OS X and the chkdsk of Microsoft Windows.

Helpful tips

To avoid losing important data on your computer, ensure that you have a battery backup plugged into your computer. With a backup, you can still shut down your system properly even during a power outage. Another option is to use an inexpensive surge protector to prevent power failures from affecting your mother board, hard drive and power supply.
