Salut,
Am urmatoarea problema:
/dev/hdb nu se mai monteaza (s-a boot-at de pe /dev/hda)
Cred ca cea mai buna descriere a problemei e data chiar de output-urile
care urmeaza
(scuze pt. lungimea lor).
Poate aveti vreo idee de cum as putea sa recuperez datele de pe
harddisk.
Multumiri,
Andrei
main:~# uname -a
Linux main 2.2.17ext3 #1 Fri Nov 17 10:28:22 EET 2000 i686 unknown
main:~# e2fsck -v /dev/hdb1
e2fsck 1.18, 11-Nov-1999 for EXT2 FS 0.5b, 95/08/09
e2fsck: Attempt to read block from filesystem resulted in short read
while trying to open /dev/hdb1
Could this be a zero-length partition?
si la fel pana la /dev/hdb8
main:~# e2fsck -v /dev/hdb
e2fsck 1.18, 11-Nov-1999 for EXT2 FS 0.5b, 95/08/09
Couldn't find ext2 superblock, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/hdb
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>
.......acelasi rezultat si pt. -b 8193
Iata si log-urile de la boot:
