Mogens, With sg_start (in the sg3_utils package) I have tried to spin up and down an ATA disk inside a USB enclosure without success. The same command on a USB connected CD/DVD combo drive did work. Could you try sg_start on your USB external enclosure which I assume contains an ATA disk rather than a SCSI (SPI) disk and report if it works? BTW I just checked libata (for SATA disks) and it does not seem to support the START STOP UNIT command. Jeff, could that one be added? > Doesn't seem it can; if I missed it, I'm sorry.. It is hard to know where to stop with sdparm ;-) At the moment I am adding transport (protocol) specific mode page support. So currently sdparm specializes in mode pages (for all SCSI command sets) and INQUIRY information (including the device identification VPD page). Doug Gilbert
