I think these drives from Plantharddrive.com are "severely OEM" That means Maxtor will not talk to you when your drive goes out. Plus, they only have a 1 year warranty. After 1 year, you can pay 1/2 the going rate for a replacement, but only through plantetharddrive.com
This is a lot different from the fairly liberal 3 year no-quibble warranty most hard drive manufacturers offer on their own drives.
