[The command is defined in SBC, MMC and > RBC.] Hi Douglas, After our previous discussion on USB/Firewire start/stop, I asked on our dk LUG for info on external interfaces, but found none that seems to implement the needed SCSI functionality. Too bad, would've been great being able to spin an external drive down/up as needed. I think I read somewhere that one ATA disk (HItachi og Fujitsu) can do something similar automatically (i.e. adhering to a timeout), once configured to do so, using MS-based utils. Dunno if those/similar are available for *nix. -- Kind regards, Mogens Valentin 2.6.12 rocks. I love the Conservative governor (not Arnold).. -- bird603568, on linuxquestions.org
