The appropriate ata(4) changes and extension of atacontrol(8) to support "spindown" was MFC'd (to RELENG_7) only 5 weeks ago. It's fairly unlikely that most users know this feature was MFC'd (case in point, I was not). http://www.freebsd.org/cgi/cvsweb.cgi/src/sbin/atacontrol/atacontrol.c has the details, see Revision 1.43.2.2. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
