I have two hard disks that were part of a RAID-5 array. Our company policy states we need to low level these drives before sending them back to the manufacturer for the RMA. I attached them to a windows box with a SAS to SATA cable and a SATA to USB cable. Windows sees the disk under disk management, but cannot initialize it. I've tried under linux\parted magic, but it doesn't see anything at all. How can I format these disks?
