I'm using 250 GB Seageate Bercudda SATA HDD

When I did the CHKDSK using windows XP it displayed the following error
(C:)

CHKDSK is verifying security descriptors (stage 3 of 3)...
Security descriptor verification completed.
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.

there are no bad sectors availabe in the HDD

then i formatted the partition C: with FAT32 and then reformatted it using NTFS and reinstalled the OS

After formatting i did the CHKDSK utility again, but the previous error was not sloved.

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

What can I do to overcome this issue.

Any one pls help me immediatly

When you re-formatted, did you actually remove the partition, or just format?

You at least need to remove partition, re boot and re-create partition.

Sometimes you need to low level format the drive.

Hope this helps

Chkdsk will mark these space as free so the file system can use it.
