I'm running 5.x and the only way to reliably calm down my disk was to umount it. The 'trick' was to use automount and periodically check & umount it, but i thought there should be better ways to handle it (or at least i hope so :). (from: "Fun With Automounting on FreeBSD" - http://www.daemonnews.org/200202/automounting.html) Any other ideas/suggestions? How do you do it? Any help from the recent ATA/SCSI/CAM/etcetc driver? It's quite annoying when your brand new USB disk starts getting hotter and hotter cause the bloody usb case is too little and there's no air circulation/fan at all... Thanks. -- Paolo
