I discovered recently that getting exactly the same size (I am using ATA) can be difficult, and two drives "the same size" can differ by a few sectors. I'm sure bigger is okay, smaller is not (but you might be able to fiddle with /boot and/or dispense with the swap partition. I prefer swap files anyway)) -- Cheers John -- spambait 1aaaaaaa at coco.merseine.nu Z1aaaaaaa at coco.merseine.nu Please do not reply off-list
