ahhhhh........ now that's over I bought 1 x raptor 150Gb, 3 x Samsung 1Tb. The raptor and one of the samsungs won't even initialize and the ther other two samsungs wont format. And when i woke up this morning the other Samsung has reproted a fatal hardware error to disk utilities What's the chances of the macpro stuffing the drives as I put them in or do you think they all could have been damaged during shipment (unlikely)... maybe the box was dropped by the courier? Was formatting does everyone use? Mac os extended (journalled) for boot drives and mac os extended for data drives 2008 Mac Pro so i'm using the GUID formatting table Q2. If i want to make a bootable copy of my system drive do I have to format it 1st as aMac os extended (journalled =) drive 1st before running carbon copy cloner?
