Thanks for the help Chris! I do not quite know how, but my card works
again!

I just mapped the /dev/sda1 device (SCSI-USB device mapped the camera) to
the C: drive in "mtools.conf"

Then I tried "mdir c:". But it failed with some file system error. But it
must have done something to the device: The next time I run 

"mount /dev/sda1 /mnt/camera"

It just worked without the "bad super block" error! Now I have copied all
my images. :)

cheers Michael
