Look at that last line.  Probably no slices will be visible until the 
integrity problem is fixed.  This could be due to the camera firmware, 
and the card might work in a separate card reader.  Or it could be an 
actual problem with the MBR on the card.  I think there is a sysctl to 
disable integrity checking, but that is a workaround, not a solution.
