Sorry about that. I can see I made a huge leap in assumption here. Ok, the /F option is used in the CHKDSK command to fix "errors on the disk". Use use this option do this:
Click START and then type CMD and hit enter. You should have a dos window. In that window type CHKDSK/F. You will get something like this:
Code:
C:\Documents and Settings\Owner>chkdsk/f
The type of the file system is NTFS.
Cannot lock current drive.
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)
Press
Y and enter. Once you do this, the next time you reboot the /F option will be used to automatically run the CHKDSK for you.
Hope that helps.
Good luck
