Yet another look at some faulty floppy drives! This time we encounter some different problems and I show how to use Test Kit to align the heads.

i love the rain noise
Just want to say thank you for this video, it has helped me diagnose a tricky fault.

dude youre becoming the internets foremost floppy expert. I've already fixed a floppy drive with your older video. next thing should be using a scope for alignment and diagnostics.
Thanks, I thought about getting the scope onto it in that video, I saw no point though - the software there on the Amiga is better than trying to do it with a scope imho. Might be useful for another drive on another system though.
@@GadgetUK164 Exactly, I have a Commodore CBM 8050 Dual Drive Floppy Disk that I have to fix. Thanks a lot for these videos.
Nice job. I needed to do a lot of what you did fixing up my old IBM laptop drive. I found taking that top plate that the top head rests on, out of the drive. Made aligning the top and bottom heads much easier. After you do that, the top and bottom heads sit on top of each other and you can clearly see if they are aligned. You just need to get your head in there with a good bit of light.
Wow amazing video which taught me alot. i have 3 drives that are behaving strange with lots of read errors on 80 % of my disks..and since im quite a noob on fixing stuff like this i never dared to try and fool around... but this video gave me really good tips on what to check for. many many thanks gadget!
@@godslayer1415wow...i..don't really know how to respond to this.. but apparently you didn't read what i wrote...about floppy drives.. or you are a troll trying to f**k up peoples diskcollections..shame on you!
The patience of a saint :)
That's some really sweet work being done here. Thanks a lot!
Wow - thanks for sharing Captain. Absolutely highly interesting (definitively the best Video I've came across so far) - 01:17:41 well worth invested time! Really really love it how far you go into the details - exactly what I need for my drives. And yes, any suggestion what kind of grease you're using yourself?
Molykote EM-30L is what I use!
This video and the previous one you did about another damn 235 are by far the best and the most in depth I've watched on the topic. Your perseverance is admirable. Can you please clarify what you mean by "adjusting the PCB" for the track 0?
Yes, that PCB (on the first model drive in this video) has elongated holes (not circular) - and the screws can be loosened allowing the PCB to slide one way or the other, and since the track 0 sensor is on there the alignment from track 0 follows with that movement.
Great work gadget! I have the same problems with some teacs and epsons, spent hours, maybe i give them another try. Didn't know there were ball bearings on the top of the spindle, i have one drive which i think is missing the ball bearings.
Nice - I love people like you going into details and even disassembling that little switch! And yes, thanks for the hint about the rain (already thought you're cooking some Popcorn in the background ;). May I ask what camera you are using? (Excellent Focus)
Thanks! It's an old Samsung (NC10 I think?)
Great one! Enjoyed the fix, thanks for posting!
Thanks =D
Scored a "broken" A500 for cheap years ago with a bad floppy detect switch. I couldn't fix the switch so I just bodged a leaf switch into the mechanism that closed when a floppy was inserted.
I had a drive with those 2 switches that weren’t working. Did the exact same thing but when attaching the bottom transparant piece it sprung off. Never found one of the springs again 🙁
Super movie !! 🔥🔥🔥 !! . It's a pity that 20 or 30 years ago we didn't have access to RUclips and such knowledge and specialists. ps: can the chip memory (2Mb) in the Amiga 1200 be replaced with a larger one (8, 16 or 32 mb - and faster with faster access)? has anyone tried this? does the addressing go through the AGA integrated circuit or through the ROM?
The 2MB Chip RAM limit was never passed by released Commodore hardware. You can get around it in emulation, and maybe the Vampire (with AGA chipset replication) it technically might be possible... What you can do on the 1200 is add a load of ZIII local Fast RAM to a CPU card. eg. TF1260 or TF1230.
@@GadgetUK164 Yes. I know. I also have a winUAE emulator. But I always thought that emulation was a blind crew. It's nice that there is WinUAE because it allows you to test many things, but we have to solve old problems from the past (we have to solve Commodore's problems). and we only need a few things to be happy. we need a new motherboard for Amiga fully compliant with the standard and new elements such as USB, network card, new sound card, graphics card with many connectors, and new solutions. without emulation if possible. the most important thing is to go one step further. that's why I asked about the 2 Mb limit to bypass it. If there was more memory on the chip, it would be possible to do more and faster.
what kind of grease do you typically use for floppy drives?
As i know molykote em-30l 🙂
Greetings where do you find the jumper settings for compatible Amiga floppy drives? cheers
See this link for info about the compatible drives:- jope.fi/drives/computolio/
Hi. The bit you removed 13-14 minutes in, I've managed to clean ok, but when I was attempting to reassemble it, one of the tiny springs when flying and I have looked everywhere for it. Are these replaceable?
If you can find a spring small enough! You might be able to find one on another FDD - or in a "spring kit" designed for watches perhaps....
@@GadgetUK164 Thanks I've ordered a spring so fingers crossed. I appreciate your videos. Really helpful! thanks!
@@GadgetUK164 Hey.. Not much success with replacement spring, can you still get the sensor switch itself?
ive recently got my a1200 out of the loft after 30 years had steve recap it at amiga passion. but im just gettin it back in a new case and afaik i dont have a working mouse hdd and i remember why it got put up in the loft in the first place my fdd corrupted all my disks i did treat it pretty badly back then im not gunna lie lol . my issue is i know no other person near me that owns any amiga stuff to test "known working stuff" so im stumped do you fix joe publics floppy drives im based in the uk ?.
Sorry, I cannot offer customer repairs! Amiga Passion, you could try Mutant Caterpillar! www.mutant-caterpillar.co.uk/shop/
Very nice video - I have never recalibrated floppy drives just yet :) - I heard the 1.76HD drives from A4000 is even more painful ?
Thanks Stefan =D
Yeah so i thought maybe I'll get around to fixing some of my floppy drives. How hard can it be? Now i know the truth. I wish i had your patience
For that head reattachment to the metal carrier I wonder if Kapton Tape would do the trick? 🙂
Kapton tape has really poor adhesion!!! Even the good stuff is nowhere near as sticky as something like sellotape =/ I think its deliberatly designed that way - to avoid leaking sticky residue on the components / board etc when used!
"This one goes to 11"
Thanks lol =D
11/11
Store the drive with a disk in!
Great idea!!!
Are Amiga floppy drives becoming so scarce it warrants spending all this time to get them working?
No, but as you should know by now - Most of what I show on my channel isn't worth the hours when you compare to cost of just buying "a working one". I dont care how long something takes to fix when it's part of a retro system.
@@ButterfatFarms what's the point of you?
@@ButterfatFarms another reply which adds nothing to the conversation but a poor attempt to inflate your sorry ego.
@@ButterfatFarms and in rey to your original feeble attempt to try belittle people with your delusional grandeur superiority. There comes a point in all retro machines where a time comes that what would have been for the scrap heap starts justifying the extra effort to salvage as numbers become less and less.
I was asking Chris, not you, had it come to the point where spare floppy drives where so expensive or hard to come by, that this effort is becoming the most viable option.
When I want to ask you a question I will @ you.
