It's a fairly typical symptom of failing hardware that any sort of bump may cause the problem to appear or disappear (consider the practise of hitting a failing TV). I think that if Adaptec had some advanced method of recognising a failing drive then they would boast about it in their marketting documents. -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
