Why would the heads come in contact with the platters on a powerfail? The arms are very rigid -- the heads only float a few thousandths of an inch over the platters -- something that I don't believe has anything to do with the platters spinning (that may *help* but I don't think the heads will contact the platters if they're not spinning) and besides -- any drive manufactured in the last 5 years will autopark on power fail... There's an awful lot of energy stored up in the spindle motor that is used to slam the heads into the parking zone... -A. _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
