upgraded to Ubuntu 11.10 - cannot see Samsung external drive

Asked by frank foster on 2011-10-19

I have upgraded to Ubuntu 11.10 from 10.04. After upgrade I can see a Freecom external drive and it mounts automatically on start up. However I cannot see a Samsung external drive would be was visible and could be mounted before the upgrade. I cannot see this drive in Disc Utility or file manager.

With the Samsung external drive not plugged in, please run this command in the Terminal (open a Terminal with Ctrl+Alt+T, paste the command in, press enter to run it, and if prompted for your password don't worry that you don't see anything happening as you type it in):

dmesg | tail; echo; df -h; mount; sudo fdisk -l; sudo parted -l

Then plug the drive in, wait between 10 and 30 seconds, and run that exact command again (you can bring the command back up in the Terminal by pressing the up arrow key).

Then select all the text in the Terminal (Edit > Select All), copy it to the clipboard (Edit > Copy), and paste it here.

Disk is detected on USB bus, and partition table can be read.
Could you run commands (with disk connected) :
   sudo blkid
   ls -l /media

frank foster (theturrets) said : #4

I ran the commands and this is the terminal screen. Still can't see the samsung drive.

What is disk /media/4AA4-03AA ?

frank foster (theturrets) said : #6

delance, thanks for looking at this problem. The drive I could not see was my business backup drive which I could not live without for a week. I have de-installed Ubuntu 11.10 and re-installed Ubuntu 10.04. I can now see all of my drives and I am working normally again, using the same hardware and USB connectors. When I next upgrade I hope I do not get the same problem. Thanks again.

Since this problem is (at least for now) resolved for you and we cannot really continue working on it because you don't have the system that was affected, please mark this question as Solved. You can do that at https://answers.launchpad.net/ubuntu/+source/gnome-disk-utility/+question/175260. You don't have to indicate any particular answer as being the solution, and you can always reopen this question later if you want and are able to work on it again.
