chkdsk /f doesn't fix anything. How to fix it then ?

[Thor_Sevan]

Hi again !

I just got this little but strange problem with win2k. I just did a chkdsk/f in windows and it found errors and asked to reboot.
I say yes and rebooted. During boot process, it does chkdsk but then suddenly the computer restarts. I remember doing chkdsk before and it should not restart. THen, during windows again if I do chkdsk it find errors. Here they are:

C:\WINNT\system32>chkdsk
The type of the file system is NTFS.
Volume label is New Volume.

WARNING! F parameter not specified.
Running CHKDSK in read-only mode.

CHKDSK is verifying files (stage 1 of 3)...
File verification completed.
CHKDSK is verifying indexes (stage 2 of 3)...
Index verification completed.
CHKDSK is verifying security descriptors (stage 3 of 3)...
Security descriptor verification completed.
CHKDSK discovered free space marked as allocated in the
master file table (MFT) bitmap.
CHKDSK discovered free space marked as allocated in the volume bitmap.
Windows found problems with the file system.
Run CHKDSK with the /F (fix) option to correct these.

So even if I run chkdsk/f.. it doesn't fix anything ! What could cause this ?!
Using win2k everything up to date as usual.

Thanks !

probably arent any problems with the filesystem. When you start the chkdsk it looks at the MFT bitmap and when it is running chkdsk, near the end, it compares it to what it originally saw and if it finds a difference it'll give you this error. Now a difference could be caused by corruption but is more likely caused by something writing to and changing the disk during the chkdsk. If you run a chkdsk during a reboot then it'll lock the drive so nothing else will change it, if it find no problems at this time then your fine.

Also, you can run a chkdsk /r rather than a chkdsk /f for a more thorough check if you want, but I'd bet money on your filesystem being fine.

CHKDSK discovered free space marked as allocated in the volume bitmap.

If you run chkdsk on a mounted volume that's expected, filesystem data in memory may not always be exactly what's on disk because it hasnt been committed yet. If you run it from Recovery Console and get the same results, then you might have a problem.

Ha ! THanks !

I did a chkdsk again with no program running in the background and it found 0 errors 😉

Everything is fine again !
