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.

Open My Computer. Double-click My Computer to open it.

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: drive is often the hard drive.

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.
