Ubuntu 9.04 won't detect hard drive in usb dock device

[servelan]

Hello! I have an (what was an) external maxtor 500gig drive, which ubuntu wasn't detecting after a fresh install.. I bought a hard drive usb dock thingy for it thinking that would help..no joy. It is full of data so I want to recover it. The drive is spinning up okay.:confused:

sudo lshw -C disk shows this:

IF it's a SATA drive/dock, can't help you.

If it's a PATA drive/dock, I encountered a similar problem and had to keep experimenting with the jumper settings until Ubuntu finally saw the drive.

mount /dev/sdb /mnt
cd /mnt
ls -l

Do you see any of your data?

It's an IDE drive, was an external drive and it stopped showing up so I took it out of the casing and docked it thinking that might help :/

Possibly a stupid question, but is there anything under the usbdrv directory that you showed under /mnt?

nope.. and those three directories are all empty anyway :/

It comes up "disk unclaimed" with sudo lshw -C disk
