I'd like to be able to make little-used SATA drives spin-down when idle for X minutes, and ideally then spin back up on access without timeouts or errors. Much like my USB-attached drives will do on their own. This is for drives that are used infrequently (eg, backup disks).
Something like SCSI's "camcontrol stop" would even be helpful, so I could script a "start" before any access. I couldn't find anything similar for ATA.
I looked through APM and ACPI docs as well as googled around without finding anything disk-specific. Anyone know if what I want to do is even possible?
(this is under FreeBSD 6.4-RELEASE though 7.x advice would be helpful too)
Thanks for any pointers
