I've had a look at the drives this morning.
The MFD-51W-10 is a complete loss, sadly. It turns out that the cable going to the top head has been ripped, so therefore, thats a complete loss.
The MFD-51W-03 is looking the best of all, this morning I pulled the head assembly out and had a look at the spring, and it was exactly as Franklinstein said. I moved it up a couple of notches until it was back to normal, and the head is now installed in the drive again. Disks insert/eject without a problem, and the head now goes all the way down, though it doesn't seem to read any disks. I've attacked it with a cotton tip dipped in isopropyl alcohol, so we'll see if that makes any difference.
The SuperDrive is looking a bit better, I've had a play around with it, and disks now insert/eject properly, but the head assembly looks like its had it...no matter what, I can't seem to get the top head to pull down like normal.
