I found this

Scandisk is used to check the file system for any problems. This utility is found on Window 95, 98 and ME systems. On Windows NT, 2000, and XP you can use Checkdisk, (chkdsk).

Occasionally your Windows PC might crash and leave a file partly created or saved, or some other problem might occur so when you run Scandisk is attempts to fix the problem, therefore reducing the likelihood of developing a serious problem in the future.

Scandisk/chkdsk is worth running every few weeks to ensure nothing is wrong, as the file system is a delicate structure. If there is a problem with it, in a worse case scenario you might lose the entire contents of your hard disk, which includes your documents and Windows installation.

The ScanDisk utility is located here...

Start > Programs > Accessories > System Tools > ScanDisk

Chkdsk can be run by running a command prompt, then typing in 'chkdsk' and the drive letter... for example ' chkdsk c: '. This will check the drive in readonly mode, fix fix any errors add a ' /f ' to the end, and reboot.

Try to run this prior to running the Disk Defragmenter
