fsck.ext2: Bad magic number in super-block while trying to open /dev/hda4



The superblock could not be read or does not describe a correct ext2

filesystem.  If the device is valid and it really contains an ext2

is corrupt, and you might try running e2fsck with an alternate superblock:

    e2fsck -b 8193 <device>
