Hi,

According to this document:

"SCSI / ATA Translation Standard"
http://hackipedia.org/Hardware/SCSI/SCSI-ATA/SCSI%20%20ATA%20Translation.pdf

The SCSI READ CAPACITY command should map to the ATA IDENTIFY DEVICE command.
I am not familiar with the ATA_CAM code, so don't know if we do this properly
for ATA_CAM.  Maybe Alexander Motin can chime in.
