Dear ubuntu-uk,
Hopefully I document this right:
# What I expected:
I have this USB drive with an encrypted partition. I have been using it
flawlessly for more than a year. With my Ubuntu computer I believe at
some point gnome-keyring saved the password and unlocks it
automatically. So we where able to view the files with no problem (two
separate users). I was able to do the same with a separate computer with
an ubuntu derivative. It was "a done once forgot how I did it" scenario
following these instructions: [1]
I am on ubuntu 14.01
# The problem:
The other day I tried the same but it does not recognize the drive.
$dmesg give me the following:

# What I tried
Looking up a solution found this bug report [2] that seems to have been
fixed? Several versions ago.
The mention using the blkid command but I am not sure what it does and
it requires root. Man page says the command will tell me the file
system but I am guessing gnome-diskutility does that for me?
Any more pointers would be great as I really want to get to the files.
