USB disk doesn't appear in file browser

Asked by Steve Franks on 2008-08-05

I've attached an external hard disk to my Ubuntu laptop, but it isn't visible in File Browser, or System Monitor.
It is probably not formatted as a Linux disk, as it came from a dead PVR. I don't think that the drive itself is damaged.
Ubuntu does try to access it, but seems to give up. Windoz does slightly better, it says that it's a Maxstor. hard disk.
Is there any other program that I can use to examine the drive?
If possible I'd like to see whether there is any data on it, but failing that I'd like to have the 80gb as extra storage.

Can you post the outputs of 'sudo fdisk -l', 'sudo lshw -C disk', and 'lsusb'?

Thank you.

Nowhere does this ominous external drive show up.

It was connected when you ran those commands, right?!

Steve Franks (stevef48) said : #4

Yes it was connected.
When I connect it to a PC it ticks, continuously in Ubuntu, for a few minutes in Windoz.

I'm all the more certain now that it's a hardware issue.

If neither OS can access it, it looks like it's going down the drain.

The constant ticking leads me to believe the bearings are gone, i.e. it constantly tries to spin up and fails to reach decent speed.

Still, as a last resort, boot your Windows, click the 'Run' dialog in the Start menu, type 'mmc' and hit Enter. Select 'Add/Remove Snap-In' and add 'Disk Management'. If it doesn't appear here, trash it.

I think that you're right.
Thanks for all the help.
