Hi Flashflood,

is this still in dos-Mode ?

what happens after a normal shutdown, if you boot into safeMode (F8-Boot) and then run scandisk ? you might alos look into the scandisk.ini-file to check its settings…

can you run scandisk after booting from a WIN-startdisk ?
if not, check BIOS settings/Detection of harddisk(s) and try disk-checking-tools by your Harddisk manufacturer (usually free)
