I looked up my hard drive model too (don't know why I didn't think about it before). It's a ST94011A, and it's listed as having 44 pins as well. But I'm still wondering about the differences in placement, etc.
One more thing, I've been looking at the place where the hard drive plugs in, and it is built with screws or metal blockings of some sort around the place where the pins are inserted, so that if the pins don't stick out from the hard drive, they won't be able to plug in, because the sides of the hard drive would hit the screws/blockings. Not sure how to describe it, but that doesn't look very promising considering how the various hard drives I've been looking at are shaped. For example, this
one would not fit because either side around the pins would hit the screws and you wouldn't be able to get the pins in.
