Is there a consensus on this? Theoretically either should be handled by the controller (a 3ware 9500s) since this is a real life possibility, but will either event cause damage to the disk? I'd suspect that removal of the data cable would simulate a disk loss with less physical trauma to the disk in question. -- Cheers, Harry Harry J Mangalam - 949 856 2847 (vox; email for fax) - hjm@tacgi.com <>
