Chkdsk is a utility that searches for problems and errors on a computer’s disk volume and attempts to fix them. It looks for things like lost clusters, bad sector problems and directory errors. If you're running into some problems on your system and you have not made recent changes to your system, running the Chkdsk utility may help to find and resolve your problem.

Sign onto your computer as an administrator. You need to have administrative rights in order to run the Chkdsk utility.
Click the Windows "Start" menu, type "cmd" into the Search field at the bottom of the menu and press "Enter" to open the Command Prompt.
Type “chkdsk c:\ ” (without the quotes) at the Command Prompt to begin the Chkdsk utility. Replace “c:\” with the letter of the drive for which you want to run the Chkdsk utility.
After the "chkdsk c:\" command insert "\f" to fix errors on the disc volume or "\r" to recover bad sectors. For more Chkdsk DOS commands visit the Microsoft website (see Resources).
Right-click the Windows “Start” menu and choose “Explorer” to open the Explorer file management system.
Select the hard drive letter for which you want to run the Chkdsk utility. Right-click on the drive and select “Properties."
Click the “Tools” tab. Under the Error-Checking section, click the “Check Now” button. If you have User Account Controls enabled, a window will pop up asking permission to continue. Click “Continue.”
Decide if you want Chkdsk to “Automatically fix file system errors” and to “Scan for and attempt recovery of bad sectors,” and click “Start.”
Chkdsk will not run if your computer is in use, therefore it will request you to schedule Chkdsk. If you click "Schedule Check Disk," it will run the next time you boot your computer before Windows is actually loaded. Turn off the computer and then turn it back on.
