defrag

[cumber46]

hi iam trying to defrag my hard drive but keep getting message chkdsk is scheduled to run on this drive please run chkdsk can anyone help?

Have you run chkdsk ?

[cumber46]

yes have run chkdsk but still unable to defrag

Open the Run box then run the command

chkdsk [drive:] /f

For example: chkdsk c: /f to check and fix errors on c:.

If the drive is locked by the system or some processes, you'll need to tell checkdisk to check the drive on next reboot.

have run chkdsk as above on reboot but still unable to defrag

Just a thought ....if your HDD is nearly full, you may hit probs with defrag, as it needs space to move files around, during the process.
It needs at least 15% free space and on some drives, as much as 25%, especially if the drive is small.

Well, your drive has more serious problem(s) than I thought :) such as bad sectors/clusters. This indicates the file system on that volume (drive) is in an inconsistent state due to data corruption or sudden shutdown of the system (causing the dirty bit to be set).

Try this command instead:

chkdsk [drive:] /f /r

The /r switch is to tell chkdsk to locate bad sectors and then recover readable information.

yes have run chkdsk but still unable to defrag
try in safe mode.

hi looks as i have solved my problem re defrag found this on another site it may help some else. run msconfig go to the boot.ini page and select safeboot
let msconfig reboot for you chkdsk runs(and so does the boot defrag). after you end up in safe mode let mscofig set you back up for normal start up i was then able to run defrag i hope it helps someone

The /r switch of chkdsk I mentioned above will clear the dirty bit set by the system due to inconsistencies found on the HD without the need to switch to safe mode.
