I only ask because I've just added a second SCSI HD to my system and it exhibits similar behaviour, although it never fails to start. The original disk is an IBM Ultrastar 2ES U/W and that spins up as soon as the power is switched on but the new disk, IBM Ultrastar 9ES U/W, doesn't spin up until the SCSI controller probes it (I thought I'd forgotten to connect the power lead the first time I powered up after installing it). The SCSI card is a Diamond Fireport (NCR/Symbios 53c875 chip). It seems strange that one disk spins up immediately and the other waits until it's probed, but since it always spins up and works without problems I've never bothered investigating further. > -- > riko > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message -- FreeBSD - The Power To Serve http://www.freebsd.org My Webpage http://www.users.globalnet.co.uk/~markov _______________________________________________________________ Mark Ovens, CNC Apps Engineer, Radan Computational Ltd.
