This could be because the processing engine on the card doesn't understand 16 byte commands (which are required for addressing capacity > 2TB) or it could just be a firmware SCSI emulator mistake. The best way of telling might be to use the SG_IO interface to send a read capacity 16. sg_readcap --16 should be able to do this. If you get a sensible response, chances are we should just quirk this device to apply RC16 first.
