Let's take an in-depth look at how to clean and fix a Sony/Apple MFD-51W-03 800k 3.5" double sided floppy drive. (Also applies to MFD-51W-10 and MFD-75W-01G 1.44mb high density drive which work basically the same way.)
This is a long and in-depth video showing you exactly the method I use to bring these drives back to life.
This drive was extremely gummed up from age so needed to be disassembled and cleaned. Then, the eject mechanism was not working correctly so I troubleshoot and fix that. Finally, the eject gear stripped so I replace that.
NOTE: Camera recorded in the wrong mode -- sorry about the worse than normal picture quality.

Apple didn't anticipate the need for the drive to last 30+ years. But the amount electro-mechanical engineering that went into this thing is very impressive.

@johnpossum556 4 года назад

Perfect timing. The storms woke me up and I can't get back to sleep. Made some tea and an Adrian repair video pops up!

I am so glad that you're saving these drives from ending up in landfills. Thisnis the most humane act of preservation of classic disk drives I've seen so far. But i wonder if cheap beer would work better than IPA. A thumbs up for you. Thanks for posting this video!

You can definitely disassemble the PCB as well, it just comes out together with the motor. he PCB is held on with plastic tabs like the cover for the gears. It's just needs a little more caution doing so.

for re-inserting the retention rings, I have used something like a small tube to give even pressure around the pin when pushing it down. In particular, I am using part of an old ball point pen that had a fairly small opening but a good way to grip it. Awesome video as always.

ARRRGH! I just moved, unpacked my collection and two of my 6 Apple 3.5" 800k drives are acting up. One has a broken gear for the eject mechanism which I can easily fix thanks to this video! The other one will works fine except it will not initiate an eject when the eject button is pushed. I've taken it apart and swapped the gear and motor with the other unit and that works, so it't not the eject motor or the gearbox. I checked the switch, and tried the switch from another unit, it's fine. I also looked over the board for bad traces, leaky caps etc. and checked the connector for broken solder joints of which I found none. If anyone has experience with a drive that won't trigger the eject motor, please chime in, Thanks!

@retroattic4647 2 года назад

looks like it was in fact the motor, it's DEAD, binding and gets warm unject an eject. I pulled the gear from that gearbox to get one working drive from the 2. Does anyone know where to find a replacement OMRON motor?

Thank you very much for the comprehensive drive cleaning/repair video Adrian! I wanted to share that I used a battery blocker from ifixit which came in a toolkit to get those black rings off around 9:00 in to the video very easily. Looks like they sell them individually too if anyone would like one. I put those rings back on with steel angled tweezers since I don't have much in the way of nails. Happy repairing, everyone.

The four “pegs” on the disk tray are sleeve bearings that often seize up. You can get work them loose again by applying some silicone lubricant and then covering them with paper towel to protect it from some plyers and gently but firmly rotating them back and forth until it loosens up, then apply more lubricant

The green on the eject motor gear was definitely oxide from the brass gear on the motor shaft

@johnpossum556 4 года назад

I am not so sure its an oxide because a lot of copper compounds are that color but it definitely was some standard copper degradation. Brass being an alloy of copper, of course. On copper roofs they call it verdigris. They're usually caused by ammonia which is why I wouldn't use the window cleaner for a job like this (unless its washed off by water afterwards)

@johnpossum556 4 года назад

en.wikipedia.org/wiki/Verdigris Read about it. Acetate and carbonate, not oxide.Copper oxide is red, picture here: en.wikipedia.org/wiki/Copper(I)_oxide The other oxide of copper is black, pictured here: en.wikipedia.org/wiki/Copper(II)_oxide You should not speak so *definitely* about things you don't know. Go back to facepalming apparently you might do that well.

@benstein7506 9 месяцев назад

isopropyl alcohol has to be one of the most misunderstood solvents out there hahah. It does not sterilize and it doesn't work well as an all-purpose cleaner. It is great for stubborn scuffs, permanent marker or other foreign stains that other cleaners can't remove, but there are cases where it still isn't enough. It shouldn't be used on any rubber components as it can accelerate dry-rot with them. I also discovered that it is not the best thing to use on all plastic compounds, especially on vintage electronics, but most ABS computer plastic will hold up fine.

I just got a Unidisk 3.5 and the disk got jammed. This video helped me take it apart to get that disk out. When I find the Lithium and Silicone I bought when I first watched this video, I will clean it like you show. Note: prior to watching this, I was able to get the lever on the right to close the door on the disk, but it was still stuck. Per your video, I removed the top mechanism (but with the disk still in, cuz it was stuck). and then I discovered a little latch on the left that was hooking the disk. It only needs to move a little bit to release, but dang it holds that disk in place very firmly and it wasn't evident to me that it was there, let alone the culprit.

@MicheIIePucca 4 года назад

working on this drive reminded me of watchmakers repair watches... while watches are much smaller, there are many intricate fragile moving parts. No doubt repairing these drives takes much time and effort. This may sound silly, but I truly believe that one needs to have a "passion" for this "hobby" to be successful, and over time that passion feeds/develops into a strong inclination that results in mastering this skill to be good at these repairs. Those with the unique personality that has this passion will never develop the inclination that comes from that passion because without the passion, you'll find yourself bored, frustrated and most likely give up. If you have the passion, it is usually accompanied with an obsession that keeps your mind works continuously thinking about how to resolve the issue, almost 24/7). Those who have this will know what I mean... those who don't won't understand :)

@KrishnaDraws 4 года назад

Adrian Black the IIGS auto eject motor seems to have a slightly different setup. The circuit is on the side of the motor, and I haven’t been able to find the openings on the housing in which to spray the DeoxIt D5 inside. Both 3.5” floppies have the same symptom, where they get “stuck” half way while attempting to eject a floppy disk. It’s been super frustrating to be so close to getting it to work but just falling short of success.

@KrishnaDraws 4 года назад

Brad Hansen I’m having the exact issue. Replaced the gear but the drive only ejects half way. I’m unable to locate the opening on the IIGS auto eject motor as it has a slightly different setup.

@ExStaticBass 4 года назад

Yeah, those posts are a pain. Try using a small socket to apply equal pressure on it's outer edge. They set better that way too because the socket isn't as squishy as we are. As for cleaning the heads. I prefer to set the q-tip between the heads and gently scrub back and fourth. It pretty much guarantees that you don't over torque them because the only force being applied is that which it was designed to endure. I would highly recommend putting your white lithium grease in a syringe because it's way less messy. Especially if you get the syringe tips for model glue that come with a cap. Hard to find but SO worth it.

Also, with regard to the pegs on the side of the upper mechanism, the guide I originally used some years back when I did this said those should spin freely, and if not just gently grip them with pliers, use some WD-40, and it should get them to spin freely again. Not sure how much that really matters in the grand scheme of things, though.

I've noticed that some lubricants applied to some plastics (can't say what for either as I've never paid much attention to it) results in said plastics disintegrating within minutes, some chemistry stuff going on there I guess, so, could be that the gear was fine and the silicone caused it to break down, personally I'd use a tiny amount of grease on those gears, less likely to cause such issues... :)

Wish someone made those gears out of metal! Fantastic job, I used to refurb the mechanisms on these drives when I worked at dealerships but never had issues with the eject motor, however that was 20-30 years ago. Nice to know how to keep them running. One thing about later Mac OS was that you could assign a particular sound for disk eject! Also the good old Talking Moose would come on and say things like, “Let me have a disk!” or “Put one of those babies in here!”, I won’t mention MacPuke although I just did, and I won’t go into a description of it, but those that remember will know what I’m talking about. Excellent video, excellent job. Only thing I’m wondering is if the PCB on the floppy ever needs any recapping.

I have a feeling that they did think about that and it was probably better to let that plastic gear fail than to have a metal gear rip into the shaft gear requiring a change of the gear and the motor/shaft assembly - the thing was spinning at a good clip when it was working.
