So I got my new toy today (pictured below). I am pumped, needless to say. My question involves the hard drives. I have 5 drive caddies, and I am not buying any more since they are INSANELY expensive. I have 4 in use and 1 free one. I decided to take the free one and pop in a 40GB generic hard drive (seagate), with NO apple firmware. Guess what, the light turned green and RAID Admin sees it as a spare, 40GB drive (see attached). So I tossed in a 500GB IDE drive, generic Western Digital Blue (again no Apple firmware) and the RAID Admin utility saw it as a 500GB Spare HD. Obviously I can't turn this into a RAID array because a RAID already exists with the other 4 drives, but does this mean Apple firmware is NOT required on the drive? I am confused by this. For what its worth this is the 2002 model of the Xserve RAID, model A1009. I would GLADLY upgrade all of the drives to 500GB drives if I knew Apple firmware drives wasn't required, but I cannot tell if this is the case or not. Can anyone confirm? I am having an impossible time finding Apple IDE drives anywhere.
