The adaptor I got to mount a 44-pin laptop IDE hard drive on a desktop machine works perfectly. It took a bit of finagling, though, since it didn’t come with any documentation, nor does the manufacturer provide any I could find online.
So for future reference, here’s a picture of both sides of a similar device:

Note that on each side of the adaptor, pin 1 is on the opposite side from where the power line goes in. This is counterintuitive if you’re guessing based on IDE drives, where pin 1 is usually next to the power.
The power line plugs in where the adaptor case has “R” and “B” on opposite sides – R is Red, positive, and B is Black, ground.
Of course, to mount any laptop drive on a desktop system, you still will have to figure out where that drive’s pin 1 is, how to set master/slave, etc.
I tried everything I could find on the net to make my toshiba harddrive
work on a desktop. It just will not work. Can you help?
