It worked before the upgrade.

I use this USB stick for short term backups, so it would be nice to solve this.

The filesystem is probably corrupted. Try it on a Windows machine and run
scandisk on it there.

Comment 2 Daniel Peterson 2007-11-25 21:56:20 UTC

RESOLVED:

well, the filesystem had become corrupted.
I reformat the memory stick and it works.

Sorry, I did not check the filesystem before the format so I could be more 
precise about the error.

Well, it works!

Thanks all
