Another fun place to look is word 0, bits 12-8 of ATA op xA1 IDENTIFY PACKET DEVICE. According to ATAPI-6, the value in this field "...follows the peripheral device type value as defined in SCSI Primary Commands...". Knowing the PDT should make you more comfortable in trying other commands. Once you know to look at MMC, MMC does provide further clues. I will stop there though because, as Pat pointed out, we are off topic. David Hawks
