Ubuntu

Cannot mount usb drive. Partition Manager says partition status is "hidden".

Asked by Samir van de Sand on 2007-05-28

Hey guys,

I recently moved from OpenSuse to Kubuntu. Before moving I backed up all my data on an external hd drive (ext3 partition). Now, I've formatted my PC and installed Kubuntu. When plugging in my USB drive, it doesn't get mounted on Kubuntu. However, when I analyzing the usb drive with QTparted, it says there's a partition on the usb drive, but its status is "hidden".

Also see this screenshot: http://home.arcor.de/ar0079218227/pub/pics/qtparted_status.png

I'd appreciate any kind of help. This is very important to me, because all data of the last years is located on this drive.

regards Samir

That looks odd. The partition type is "free". This command should list the partitions:-

sudo fdisk -l /dev/sdc

What do you get?

You could also run a check on the partition:-

fsck /dev/sdc1

If you have enough space though I would "dd" the entire image onto your hard disk before you mess with it, just so that if it does go horribly wrong you have a copy of it.

dd if=dev/sdc1 of=~/backup_of_disk

Disk /dev/sdb: 251.0 GB, 251000193024 bytes
255 heads, 63 sectors/track, 30515 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot Start End Blocks Id System

fsck /dev/sdc1
fsck 1.40-WIP (14-Nov-2006)
e2fsck 1.40-WIP (14-Nov-2006)
fsck.ext2: No such file or directory while trying to open /dev/sdc1

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>

Looks pretty bad I guess. Is this partition still recoverable ?

Try these steps:
open new terminal:
tail -f /var/log/messages

then connect your USB, then look at the logs it will show you i.e (USB /dev/sdb) this is example.

then run : mount /dev/sdb /media/usb

make sure you have usb folder or your mount point.

Yours,
Waleed

Hey guys,

the problem is even worse now!

I've played around with "Disks & Filesystems" under the system settings. Now my IPod does not mount anymore!

Does anybody now I can my Ipod working again without reinstalling Kubuntu?
