What exactly is a bad sector in your hard disk?

Bad sectors are damaged sectors on your hard drive where the computer can not read or write data in it anymore.

How do Windows XP handle bad sectors?

Windows XP or any Windows Server operating systems handle bad sectors intelligently. When bad sectors occur on your hard disk Windows will mark the damaged sector as bad so that it will no longer be used anymore for data storage. If the bad sectors was used to store data, then Windows will use the spare sectors in your hard disk to store and move the data from the bad sectors to the spare sectors, of course this will happen if the data in the bad sectors can still be accessed and read by windows. In the event that WIndows can not move the data from the bad sectors you will be in to a big trouble.

This happens when your computer encounters problems that windows can not handle or to prevent your computer from more damaged caused by an offending device on your computer. This device will absolutely be the hard disk on your computer. The Blue Screen Of Death will appear either during booting up your computer or while loading your favorite programs on your computer but it all depends on when Windows will access the data on your bad sectors, If WIndows reads the data in the bad sector then BOOM!

How do we fix bad sectors?

Fixing bad sectors in your hard disk requires low level formatting of your hard drive.

If you can not Low level format your drive then its time to move on disconnect your hard disk from your computer and toss it into your trash bin and go call your local hard disk dealer and order one for your computer. :)
