I have a HD that refuses to mount with a 'bad magic number in super-block'.
[root@moe ~]# mount -t ext3 /dev/hdc /Big-Drive/
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
To get a listing of all the superblocks, I did:
[root@moe ~]# mke2fs -n /dev/hdc
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
30539776 inodes, 61049646 blocks
3052482 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
1864 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632,
2654208,
4096000, 7962624, 11239424, 20480000, 23887872
Next, I tried:
[root@moe ~]# e2fsck -b 32768 /dev/hdc
e2fsck 1.39 (29-May-2006)
e2fsck: Bad magic number in super-block while trying to open /dev/hdc
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>
Subsequently I tried the above command and substituted each of the
superblocks listed above with the same results.
Have I missed something? Is there any hope at all for my data?
Thanks for any pointers!
