I have a Toshiba AC100 computer. It used to have Android installed, but then I installed Ubuntu onto one of the flash drive partitions. Some other partitions from Android remained untouched.
They can be mounted as ext3 without problems in Android, but fsck.ext3 fails to check them -- https://bugs.launchpad.net/ac100/+bug/1046455:
root@potka:~# umount /dev/mmcblk0p7
root@potka:~# fsck.ext3 /dev/mmcblk0p7
e2fsck 1.42 (29-Nov-2011)
fsck.ext3: Superblock invalid, trying backup blocks...
fsck.ext3: The ext2 superblock is corrupt при попытке открыть /dev/mmcblk0p7
The superблок could not be read or does not describe a correct ext2
ФС. If the устройство is valid and it really contains an ext2
ФС (and not swap or ufs or something else), then the superблок
is corrupt, and you might try running e2fsck with an alternate superблок:
e2fsck -b 8193 <устройство>

Is this some kind of a well-known problem of e2fsck from Linux?
