I am 90 % sure the drive is fine :-( - Was copying data from it yesterday.
Lent the drive from a mate to copy data, now it can't be found, plugging in and out no change - AAAHHH he is going to KILL me. Please help :-)
Here is the Ubuntu official guide to automounting USB:
https://help.ubuntu.com/community/Mount/USB
If you have Ubuntu 10.04 Lucid Lynx, maybe you can take a look at this guide here:
http://www.webupd8.org/2010/05/fix-usb-devices-automount-not-working.html
You can also try to use Disk Utility, available in the Ubuntu Software Centre:
https://apps.ubuntu.com/cat/applications/natty/gnome-disk-utility/
The link first suggested under "Ubuntu official guide to automounting USB" suggests
Disks (the GNOME disk utility) that lists drives, including USB drives. If you click a drive on the list, you can view its details, and can click the triangle-shaped button (Play button) to mount the drive.
This worked first time when a USB memstick suddenly refused to automount under Thunar File Manager. After mounting it pops up in the File Manager.
Try this also: This has something to do with the BIOS and floppy drives.

This worked for me when nothing else did. I tried:
sudo apt-get install dconf-tools
dconf-editor
sudo apt-get install usbmount
pmount
Finally I did modprobe as described in link which worked!
sudo modprobe -r floppy
sudo fdisk -l
anddmesg | tail
