Hi, I noticed hdparm doesn't work well on external USB drives. Try a hdparm -I /dev/sda and see it fail with a "HDIO_DRIVE_CMD(identify) failed: Invalid argument". (I notice this on both a 2.4 and 2.6 kernel and with hdparm-6.1.) My question is whether this is a shortcoming in the usb-storage driver, or because of some shortcoming in the firmware of the external drive (case). Or is it because the usb-storage driver uses emulated SCSI and this is why these commands fail? I would like to get these commands to work so I can password protect these drives with the new security commands introduced in hdparm.
