Hard disk failure is possibly the worst thing that can happen to your computer and it often occurs without giving any warning signs. The main cause of these failures are bad sectors.

A bad sector is a sector on a disk drive or flash memory that cannot be used due to permanent physical damage to the disk surface. This can happen due to improper handling, or if the disk abruptly loses power while it was in use, or if the disk is failing.
The typical symptoms of disk errors are blue screens (BSOD), slow computer, file corruptions, and other random errors. You may either run Chkdsk from the command line (see details) or launch Windows Explorer, right click the drive that you wish to examine and choose Properties. Switch to the Tools tab and click the “Check Now” button under Error checking. Select “Scan for and attempt recovery of bad sectors” to perform a thorough disk check.
