IDENTIFY DEVICE command has *no* parameters.Alan was talking about ATA_16, which has to contain payload data in SCSI format for the encapsulation to work, so for a command that returns 512b the ATA_16 has to contain this as the data length. Sounds like a Mark Lord problem to me ... cc added.
.. Errr.. yes and no. Yes, because nobody else is likely to do anything about it, so I will work around the hardware bug by updating hdparm. But no, there's no funky missing data length issue there. Just a bridge chip that doesn't understand ATA_16 commands. Apparently it *does* understand ATA_12 commands, though, so perhaps hdparm will simply use ATA_12 for IDENTIFY from now on.
