Some Common surveillance Hard Drive Problems.
Three Methods:Windows
XP, Windows 7, Windows 8
Bad sectors are sections of your computer’s hard drive that
have been damaged, and have lost the ability to save and store your
data. If your computer makes grinding noises when using the hard drive,
that’s a good sign that your hard drive has bad sectors. When you repair a bad
sector, your computer will replace the bad sectors with good sectors and ignore
the bad sectors. The methods for repairing bad sectors are different, depending
on what version of Windows you’re using. (This is all falls under
common hard drive problems )
The larger your hard drive, the more sectors there are to
check, and the longer this process will take. Start this process when you won’t
need your computer for a while, such as overnight.
Windows XP
Close all of your open programs and files. Windows XP
can’t scan or fix a bad sector if that sector is being used by an open program
or file.
Windows XP uses a system utility called Chkdsk to scan for
and fix bad sectors.

Choose a
hard drive to check for bad sectors. In the Explorer window, in the
sidebar, right-click the hard drive you’d like to check for bad sectors, and
then click Properties.
The C:

In the
Properties window, click the Tools tab.
In the
Error-checking section, click Check Now.
Choose the
Check Disk options you’d like to use. In the Check Disk dialog box, you
can have Check Disk fix file system errors it finds and recover bad sectors.
If you’d
only like to scan for and fix bad hard drive sectors, make sure
that Automatically fix file system errors is unchecked.
Click Start. Windows
will start checking your hard drive for bad sectors and will fix any that it
finds.
If you
have any open files or programs at this point, you’ll get an error message
asking if you’d like to schedule the disk check when you restart your computer.
If you click Yes, it will restart your computer and perform the disk
check.
Review
the Chkdsk report. When it’s done.
