No one likes the experience of a hard disk crashing. In just seconds, a lifetime of work can be gone leaving you in tears and with a huge problem.

Hard drive crashes are identified as either logical or physical. Logical crashes are caused by a virus, file system or software error. On the other hand, physical crashes are those caused by heavy impact on the unit, a strong magnetic field passing around the computer or a mere voltage fluctuation.

A logical hard disk failure is when the data becomes unreadable due to a virus, corrupted software, or a faulty file system. Physical crashes, on the other hand, can be caused by a number of things such as fluctuating voltage or a scratched or broken hard disk.

However, it is still best to leave the recovery to the experts, firms that are into this type of work. To recover the data, sometimes, a combination of the two areas (logical and physical) are acted upon.

When recovering data from a damaged drive due to logical error, one needs a working computer installed with the software needed to diagnose and repair the hard disk.

For logical disk failure, there are a number of utility tools. These tools scan the hard drive for bad sectors and move the data on the bad sectors to good sectors. Virus removal tools are also used to detect the presence of a malicious attack. Most operating systems such as Leopard, Windows, or Linux come with a variety of disk utilities that you can use to recover from logical errors. NTFS, ext3, and XFS are newer file systems that also guard against disk failure.

For physically damaged hard disks, special electronic equipment are needed to save the data. Devices that detect electromagnetic forces are used to save data from the remaining good sectors.

A number of online guides are available to the user bent on saving his./her data.

Aside from data recovery advice, the writer also frequently publishes information on the car audio system and the cordless expandable phone system.
