and SCSI tape drives). It also can list VPD pages including
the device identification page.

Nice! Just got it and tried on an external usb disk.
One feature I could use, probably others as well:
Could you add the ability to spin down/up a scsi disk?
I'd really like this for exteral (usb) disks.
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).
