    What it says: repair the disk manually and reboot. This does not mean
    reinstalling Debian.

      fsck -y /dev/hda3

    should fix almost everything (-y means answer yes to all questions,
    which you ought to do). Afterwards, look in {partition}/lost+found for
    any disconnected files that fsck may have recovered.

    You go ahead any way. You're in single user mode and no other processes
    are going to be changing the partition.
