Međutim, kada sam došao do dela za proveru fajlsistema
e2fsck -f /dev/sda1
javio se sledeći problem
root@sakidesk:/# e2fsck -f /dev/sdb1
e2fsck 1.41.12 (17-May-2010)
e2fsck: Group descriptors look bad... trying backup blocks...
e2fsck: Bad magic number in super-block when using the backup blocks
e2fsck: going back to original superblock
Superblock has an invalid journal (inode 8).
Clear<y>? no
e2fsck: Illegal inode number while checking ext3 journal for /dev/sdb1
Pretpostavljam da je stvar zeznula komanda
tune2fs -O ^has_journal /dev/sda1
za kojom možda i nije bilo potrebe, pošto je uputstvo staro i verovatno je tada bilo problema da se odradi resize2fs za ext3 fajl sistem.
Dakle, moje je pitanje da li mogu nekako da popravim superblock?
Probao sam da sledećom komandom vratim opet ext3, ali ne ide
root@sakidesk:/# tune2fs -j /dev/sdb1
tune2fs 1.41.12 (17-May-2010)
The filesystem already has a journal.
Takođe sam probao i sa komandom
root@sakidesk:/# mke2fs -n /dev/sdb1
mke2fs 1.41.12 (17-May-2010)
/dev/sdb1 alignment is offset by 512 bytes.
This may result in very poor performance, (re)-partitioning suggested.

e2fsck: Bad magic number in super-block while trying to open /dev/sdb1
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>

Znam da problem nije lako rešiv, ali bilo koji komentar je dobro došao. U pitanju je particija na kojoj su filmovi, tako da nisu baš izuzetno bitni podaci, ali opet ne bih radio formatiranje :)
