Good job you went for the maxtor. They may be slow but better chance of them not crapping up as much as that particular IBM model.
The 75GXP and 60GXP models die on you, checkout places online where america are sueing IBM cos of this.
From personal experience I had to buy a SeaGate HD as a backup, since my IBM was messing up and making these clicking noises. Also got some CRC errors while backing up files. I have the 60GXP. Hopefully send it back to IBM sometime next year, since for some reason it is working again, and so no point in sending them a working HD.
