mischien booten met uw Xp cd, windows repair kiezen en dan CHKDSK /F (is niet in XP maar toch niet moeilijk.)
If your Windows XP CD does not give you the Repair (Recovery Console)
option when you boot from it then you need to download the 6 diskette
set of boot disks from Microsoft
Obtaining Windows XP Setup Boot Disks

Use these diskettes to boot the computer, starting with #1 and
inserting the others when asked to do so. When the process is
complete it will stop at the A:\> prompt and you can then use the
CHKDSK /R command as described above.
