Subject: sdparm cannot start or stop SATA disks
Date: Fri, 29 Jul 2005 20:47:51 +1000	[thread overview]
Message-ID: <42EA0957.9010408@torque.net> (raw)

Putting this post on this list might head off
more (private) emails on this subject.

sdparm uses the START STOP UNIT SCSI command to start
and stop (spin up and spin down) SCSI devices.
Currently libata does not implement that SCSI command.
[Hopefully Jeff contradicts me.]

Has anybody seen a USB or 1394 enclosure that implements
START STOP UNIT? [The command is defined in SBC, MMC and
RBC.]
