Hrmm, Maxtor 80? Quite possibly. Haven't really used Maxtor for years, so not sure. Definitely something to check out though.
Crashman is talking about a jumper that limits drives to 32or 38, can't remmber, GB, to help make it compatible with more systems. Look on your drive to see if it has that. If so, remove it. Know I had a batch of IBMs that had that problem, jumper was on by default, and since I didn't build those systems, just suggested the parts, didn't come up until later(somehow that programmer and admin never noticed they only had half the space they were supposed to. Go figure)
