I just purchased a HP 8100 internal ide cd-rw (it's exactly the same as the sony crx100e) drive on that auction site that starts with an e (please don't kill me). The auction description stated that he knew that it was broken, so I knew what I was getting myself into, buy I bought it anyway with the hopes that I could fix it or that one of the geniuses on this board had run into the same problem before.
The seller said that the drive had been working perfectly for the past year and that he tried to open it one day, but pushing the eject button would not open it, thus the drive can only be opened by manual ejection, which is really a pain. First, I took off the top of the drive so I could see what was going on internally. When I hooked up the drive and pushed the eject button, its led flashed 50 times very quickly in a row and then ceased to flash (I'm assuming that this is what it would do when it's opening the drive, but I've never seen a working one, so I don't know). Then, I pulled the tray out. Upon pushing the button again, it flashed as before (what it would do while it's closing, I think). If, however, I move the gears by hand to move in the tray while the light is flashing (so the drive thinks that the tray is closed), the spindle will start to spin as if it were reading the disc). I don't really know what's going on here, but my guess would be that the motor is burnt out (especially because the motor has the same smell that a power supply that I once fried did). If this is the case, can I cut the tray motor off of my 4x cdrom that I never use and resolder its power connects to the cdrw drive to make my drive happy? How would I do so? Upon looking at the motor, there are no red or black wires emerging from it, even though it otherwise looks exactly like the motor from my 4x drive. Right where the motor sits on the other side of the pcb, in fact, there are 4 solder spots, of which only 2 appear to be used, and by which are printed on the pcb the words "tray in" and "tray out". I've got a pic of the motor (incase you could figure out the voltage / specs of it by the label) and of the solder spots at

If the fix is not just a simple soldering job, does anyone know of a vendor that sells the internal circuit boards of these drives? HP won't sell me just the part, they're gonna charge me $155 to fix the drive (3X what I paid for it). . .
I greatly appreciate any help that you could give me.
Thanks,
Shawn
