IDE interface pins broken off
Here I have an old Maxtor diamondmax plus 8 with 2 IDE interface pins bent.
I believe the drive could be OK, but when I tried to straigten the two pins... yes, they broke off :-(( It is the last (or first?) couple. How can I identify what pin numbers they have? It is the pins nearest to the master/slave jumper. Is there any chance I can still use the drive? -- regards, |\ /| | \/ |@rk \../ \/os |

I haven't had that exact problem, but in the past when I've had an obvious problem with the circuit board, which includes the connector, I've been fortunate to have another drive available that I can borrow the circuit board from. I do a temp install, grab the data, wipe the drive, and trash it. Reinstall the circuit board on the donor drive. Ideally, the donor drive will be identical to the problem child, but I've had good success as long as the donor drive is a member of the same family/series. As for can you still use it, the quickest thing to do is plug it in and check. It depends on which pins are broken. |

I've actually replaced pins by salvaging them off of an old/dead drive One of the pins is a ground and probably redundant but the reset pin may be a needed function |

It is the pins nearest to the master/slave jumper. Is there any chance I can still use the drive? http://pinouts.ru/HD/AtaInternal_pinout.shtml The IDE connector has a keying slot on one long edge, and there is a "missing" pin which is the tenth pin from the pin 1 end. The "missing pin" should be side-opposite from the keying slot in the shell. Since the pins go 2,4,6,8,10,12,14,16,18,20... that "missing pin" is actually numbered "20". Using a drive as reference here, I think that means you've busted off pins on the "GND / RESET" end. Losing a ground isn't necessarily a big deal, but I don't know the details of how 80 conductor cables are made, to tell you whether one ground is used to drive the 40 ground wires on the cable or not. If the broken ground only went one place, it might not be that important to overall function. Losing RESET doesn't sound like a good thing... I was going to say something like "just replace the connector with a soldering iron" but when I looked at mine in more detail, it's a surface mount connector. And that means the spacing would be tight, and less worthy of a "home project" than an old thruhole connector would have been. I've probably replaced a thruhole connector like that, but it's still a "swear word" experience. You need to use the solder sucker and solder wick, to clean the holes in preparation for a replacement right-angle thruhole connector. In a scene of desperation, you'd also have the option of soldering a ribbon cable right to the drive. (I would use an older 40 wire cable in that case, then cut a connector off the "two connector" end. Using a 40 wire cable, is to avoid having to figure out what to do with an 80 wire cable.) So if your connector is a surface mount one, things aren't looking good for doing a repair. Maybe you could get it off the board, with hot air, but then the fun part would be getting the new one on. If there is a high quality solder mask, it's easy. The solder won't stick to a solder mask, and masking the contacts for a surface mount connector, helps prevent solder shorts between contacts. But you really need the proper tools for the job. Just pointing a heat gun at the thing, is going to melt solder on small adjacent components. and that isn't good. A hot air rework station, you buy an adapter with the right shape, to just heat the area that needs to be melted. (Our rework station had about 20 different adapters in the drawer underneath it.) And that's how you'd get another surface mount connector properly fastened. I suppose you could always take a twisted pair of wires, make the black wire GND, make the red wire RESET, and make a connection from the motherboard to the drive, to bypass the open circuit caused by the connector. That would be yet another option. RESET may not require transmission line quality connections, so it might work. Whereas, doing that with "DD7", "DD8" and the rest of the data bus, would be much more risky. Using a twisted pair, is to try to match the impedance of the cable. Paul |

I don't have an old IDE drive I can look at, but if the solder points for those two pins are accessible, then you could split the wires on the ribbon cable, cut the two wires next to the plug, and tack them to their corresponding point on the PCB. Steady hands, pinpoint accuracy, and a tiny soldering pencil are the order of the day :-) -- SC Tom |
