Getting disk errors when trying to defragment the disk drive

[Zog]

I'm trying to run a disk defragment, and I get the following error:

"Defragmentation of ( C: ) has been aborted due to inconsistencies that were detected in the filesystem. Please run CHKDSK or SCANDISK on ( C: ) to repair these inconsistencies, then run Disk Defragmenter again."

I opened up a command prompt window, and run chkdsk. It had to schedule itself to run at the next reboot, so I rebooted the system. The chkdsk ran fine, and detected no errors. So after the system came up, I tried to run the defrag again, and still no dice, same error message.

I tried to locate the SCANDISK utility, but I don't seem to have it.

Thanks

Boot into safe mode. Once there, click on Start then select Run

type CMD

when the window opens type

defrag c:

and then press Enter

How do I boot it into safe mode? The message says I need to run chkdsk or scandisk, I assume defrag c: from the command prompt runs differently?

To Start in Safe Mode press the F8 function key during boot up.

You have to press it at the right time, so when it starts booting, just press it once every second or two and a message appears that it is going into safe mode.

You said you already ran chkdsk successfully so I don't understand your query.

After you are done, reboot normally.

I got into Safe Mode OK, and ran chkdsk, this time with a /f on it, like:

chkdsk /f

I got the same message about scheduling the check disk after a reboot, so I rebooted and the chkdsk /f ran. It was different this time, it at 5 steps instead of 3. Same results as before, no errors found.

After the system came up, I tried the defrag again, and got the same message yet again:

"Defragmentation of ( C: ) has been aborted due to inconsistencies that were detected in the filesystem. Please run CHKDSK or SCANDISK on ( C: ) to repair these inconsistencies, then run Disk Defragmenter again."

So this is the situation: chkdsk finds no errors, but the defragmentation program says there are errors on the drive, run chkdsk or scandisk. And, I can't find a scandisk on my system. This is Windows XP by the way.

Thanks for your help!
