memory stick

Peter Shepard · 03-13-2007, 07:09 PM

I can't access my memory stick. I have tried to mount it using "sudo mount /dev/sda <DIR>" and get the following error

mount: /dev/sda: can't read superblock

also I 've done a "sudo /sbin/fsck /dev/sda" and get this error

fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)
fsck.ext2: Invalid argument while trying to open /dev/sda

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>

Running this command "e2fsck -b 8193 /dev/sda" gives me

Am I out of options here or is there anything on the disk that is recoverable?

what is the output of 'hwinfo --partition' (as root)
after you've plugged in the stick ?

if the first partition on the stick is /dev/sda1 for example, mounting /dev/sda won't work.

I type "sudo hwinfo /dev/sda"

and get

sudo: hwinfo: command not found

sorry,

--partition is an option to hwinfo.

Code:

hwinfo --partition

if that's not installed, try to get it or:

Code:

fdisk -l

should show most available partitions (some fancy compaq smart array controllers don't show up)
so if your usb-disk shows up as device /dev/sda and has been partitioned + filesystem created fdisk should list those partitions and you can figure out which are valid for you.

try /dev/sda1 instead of /dev/sda
