I went out and purchased a hard drive replacement for my xbox, but not sure I got one that will work. I bought a Maxtor 120GB ata 133 7200rpm hard drive. Does anyone think it will work or should I take it back and swap it out for a different one? I got a really good deal on this hard drive about 70 dollars. Also can you please tell me what would be the difference between ata 100 and ata 133. Thanks.
