I think my Sandisk Cruzer 32G u3 stick died when I plugged it into a medion cassette tape to mp3 ripper (but I can't be sure).
Now it just presents itself as a dumb old memory stick (with no CD and all my data gone).
I took a dd backup of the stick and ran various recover tools to find continuous files but nothing is recoverable.
What is worse is that the CD partition has shrunk to zero and all attempts to put it back run without error but make no difference.
The CD size always reports as 0. I wonder if the problem is because the partition count is 0x01 but I don't know how to change that.

lpinstaller would not recognize the drive.
After formatting it as a single partionless drive, lpinstaller did recognize it.
However it was not able to install the u3 launchpad or re-create the cdrom device.
