| |
Dear list,
I am looking for what the current state of USB SATA timed spindown of- disks is ata this time. I've been reading documents and mailing lists- for every possible search I can dream up on the subject. Suggested- workable solutions include (but are probably not limited to):
$ hdparm -S This seems to be the ATA way of telling a disk to spin down, and it works in some situations, but doesn't appear to work on USB attached disks under 2.6.25
$ sdparm This is suggested in a small number of locations. Most of which have examples on how to disable STANDBY on a handful of devices. I am unable to find any evidence that it can actually be used to enable power saving.
$ scsi_spin Requires the disk to be unmounted, and I can't find anything saying that this is how the world is supposed to be.-
I'm hoping that perhaps I'm missing something from this list.
I don't really know whether this is a topic for the scsi people, or the- SATA people, or the USB people. So I'm asking here instead to try and get my first hints from the parent group.
Thanks in advance,
hachi
