Apologies if this has already been asked and answered before.

My 8.10 USB Boot stick, which I had been using for several weeks, has become unreadable and I need to get some data off it. Also, I'd like to know how I can prevent this in the future.

The stick is a 4gb PNY Micro Attache. It worked perfectly until a couple of days ago, half worked for about a day (stupidly, I did not concentrate on getting data off it!) and now it won't boot at all or even appear as a drive under Windows or Ubuntu.

If I do tail -f /var/log/messages and then plug it in, I get the following:

and then nothing after that. lsusb takes a long time and finally gives me this:

I installed it using [System]->[Administration]->[Create USB Startup Disk] so is should be set up so it doesn't hammer the drive shouldn't it? Having said that, the drive only cost me about £15 so it may not be that robust.

Any suggestions how I can get the data back from this stick and how to avoid the same problem in the future (maybe I should keep another stick for the data!)
