How to display Errors found and Repairs made by CHKDSK

• To run Chkdsk in read-only mode, at the command prompt, type chkdsk, and then press ENTER.
• To repair errors without scanning the volume for bad sectors, at the command prompt, type chkdsk volume:/f, and then press ENTER.
  
  Note If one or more of the files on the hard disk are open, you will receive the following message: Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)Type Y, and then press ENTER to schedule the disk check, and then restart your computer to start the disk check.

  Windows Vista & Windows 7
  You can launch CHKDSK using two methods (the former being the easiest):
  
  Graphical Interface:
  
  Open the Computer option from the start menu, which will display all of the drives available to scan on your PC:
  
  
  Then, right click on the drive you wish to scan for errors and select Properties:
  
  
  Now click the Tools menu, then Check Now under the error-checking section:
  
  
  You have several options within the check disk tool. It is always recommended you leave the "automatically fix file system errors" box checked, as this repairs and problems found. If you want to perform a deeper scan, tick "scan for and attempt recovery of bad sectors". This second option takes longer, but is worth doing if you suspect a drive problem. Once you are configured, click Start:
  
  
  If you try to check a disk that is currently in use, you will receive a message asking if you wish to schedule a scan. Accepting this will perform the scan next time you restart your PC:
  
  
  Good Luck!

Go to the Windows Command Prompt. You can do this by clicking first the Start button and then clicking the Run button. After this, type "cmd" in the Open text box and press Enter.

View the displayed Command Prompt screen.
If you want CHKDSK to run in read-only mode, type:
CHKDSK c:
If you want CHKDSK to fix errors and not to check bad sectors, type:
CHKDSK c:/f
and press Enter in the Command Prompt.
If you want CHKDSK to run thoroughly; that is, fix errors, find bad sectors in your hard drive and recuperate still readable data, type:
CHKDSK c:/r or
CHKDSK c:/p and press Enter in the Command Prompt.

Initialize the properties of the hard drive you want CHKDSK to run. Open My Computer. Right click your mouse on the drive in which you want CHKDSK to run. Click the Properties button and click the Tools tab. In the Error-checking box, click the Check Now button.

Set up the Check Disk options by checking one or both check boxes displayed. These are labeled "automatically fix file system errors" and "scan for and attempt recovery of bad sectors". If you want CHKDSK to run in read-only mode, do not check either box. After this, click the Start button.
