hdparm *does* try to issue the PACKET IDENTIFY whenever

Could you perhaps try and see where that ioctl() is failing?
Ah.. Okay, so that's the second HDIO_DRIVE_CMD. I'll test why the
second one is failing tomorrow.
Okay, I suspect it's failing because libata-scsi *always*
forces passthru commands to go via atapi_xlat, even when
the command itself is not a PACKET command. Doh!
I'll see if there's a sensible easy fix for it, and maybe post
a patch here unless you beat me to it.
