Pisces R3 filesystem corruption?

Fri Jul 13, 2012 12:01 pm

I downloaded this image and used dd to copy it to an 8GB SD card (as I did with the Wheezy image). I then loaded up GParted with a view to expanding the filesystem. GParted reported a problem with /dev/sdb3 and would not cooperate, giving an e2fsck command to fix it.
I exited GParted and tried this command, but got:

Code: Select all

$ sudo e2fsck -f -y -v /dev/sdb3
e2fsck 1.41.14 (22-Dec-2010)
e2fsck: Superblock invalid, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/sdb3

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>
(to clarify, the alternative command also failed with the same message). Is the partition corrupt at "source"?

Sorry, ran out of time to edit. Further information, I get a kernel panic on that partition whilst loading into QEMU (I'm still waiting for the PI to arrive!).

Return to “Raspbian”
