I'm trying to format a 32GB USB flash drive to ext3 for Linux.
sudo tail -f /var/log/messagesshows me:
Jan 1 23:40:42 rj kernel:
[13773.966516] sd 11:0:0:0: [sdb] Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK

[13805.936223] sdc: sdc1
[13805.939802] sd 12:0:0:0: [sdc] Attached SCSI removable disk
And then hangs.
sudo fsck /dev/sdb1shows me:
fsck from util-linux-ng 2.16
e2fsck 1.41.9 (22-Aug-2009)
fsck.ext2: No such file or directory 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>
Trying that last suggestion gives me the exact same message. Same using -b 16384
Palimpsest Disk Utility shows:
34 GB Unrecognized
Unknown or Unused
My general question is: how can I fix the corrupted superblock and do the format?
[Apologies if this is the wrong forum for the question.]
