That's just nuts.
No its not. If the disk is asked for data from such and such a sector in order to issue a stop command to a machine, IMO it has its seek time + 1 revolution to get that data under a head and read. If its spun down then it will have to also spin the drive up which may take 2 or 3 seconds. That IMNSHO is a huge error that in some scenarios, could get somebody maimed or killed. So we'll have to agree to disagree. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
