Copying files with "Roxio Restore" on XP - system hangs if any other app tries to access DVD drive. And left a corrupted file on /dev/hda1 - /mnt/WinF, ext3.
On boot in Linux, "check forced" "try manual fsck" at some point, and it was taking a looooong time - thought it hung. So, booted with Mandrake CD1, "rescue" at boot prompt, got a shell, mounted the root partition, edited /etc/fstab to comment out mounting /dev/hda1, deleted the corrupted files, booted normally. Then man fsck, gave
fsck -t ext3 /dev/hda1
The filesytem still had errors.
Corrected the errors when it asked, finished in around 15 minutes or less. Phew!
