Hi all,

I am trying to defrag my C: but when I select either to Analyse or Defrag, a message box appears stating

"Disk Defragmenter has detected that Chkdsk is scheduled to run on the Volume C:"
 Please run Chkdsk /f

What does this mean? I've never had any problems like this before and have never heard of Chkdsk/f.

Many thanks in advance,

Go to your command prompt (Start>Run>CMD) and type

chkdsk c: /f
When prompted to schedule it on next reboot say yes and restart your computer. It is a disk check similar to Windows 98's scan disk.

Check control panel>Scheduled Tasks to verify whether or not chkdsk is scheduled to run

Windows has detected that something is wrong with the file structure of your hard drive, so before defrag goes off moving corrupt files around, it wants to make sure that all files are good before it moves them around.  chkdsk is the check disk program for your hard drive. /f tells it to fix the files that it finds something wrong with.  It can't do it to your C: drive while windows is running since some files are in use, so you can schedule it to run on your next reboot before Windows fully loads.
