Any computer modern enough to be doing ATX auto-poweroff should have modern enough hard drives that even a write behind cache is not a problem. Relize it was over 10 years ago that the spindle motor enertia was found to be enough to use the motor as a generator for the period you need to keep the drive running after power has been cut to write back the cache data. Can anyone show me a drive made in the last 5 years that fails to properly write it cache data on DC power loss? If so I'll show you a design flaw... one I know first hand that there is no good reason for. -- Rod Grimes - KD7CAX - (RWG25) rgrimes@gndrsh.dnsmgr.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
