I've been having some problems with getting an USB drive to appear. First I connected it to my Ubuntu laptop and the drive appeared and I could format it with the ext file system. Then I moved the drive to another computer that is also running Ubuntu and the drive won't appear in GParted or other tools. Could you recommend a way to proceed? Thanks
UPDATE. Here's the output from $ dmesg | tail
