Have you tried 9.04?

I have been using 8.04 and trialled 8.10. I have just bought a
Fujifilm and found that it couldn't read the card via cable. Seems
9.04 have solved that problem in 8.04 and 8.10 whatever it is. Just
thought it was worth mentioning - 8.* doesn't seem to cope with cable
connecting with some cameras. I could use the card reader though.

Using Recuva seems a good suggestion and reformatting the SD card -
something wrong there i think.
