Bad magic number in super-block
I have installed linux FC3 and windows2000 on one PC like this:
Disk /dev/hda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 766 5864 40957717+ 83 Linux
/dev/hda2 10851 19457 69135727+ 5 Extended
/dev/hda3 * 5865 10850 40050045 7 HPFS/NTFS
/dev/hda4 1 765 6144831 4d QNX4.x
/dev/hda5 10851 10913 506016 82 Linux swap
/dev/hda6 10914 19457 68629648+ b W95 FAT32
I have rebooted from win to linux but grub reported error 17.
I have tried to check partition with Knopiix 3.7:
# fsck.ext3 /dev/hda1
e2fsck 1.35 (28-Feb-2004)
Couldn't find ext2 superblock, trying backup blocks...
fsck.ext3: Bad magic number in super-block while trying to open /dev/hda1
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
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
Please can you help me fix this problem?
