Here is an A1200 shugart floppy drive that was claimed by the previous owner to have a problem with the disk write-protect functionality. The drive was given to me since the previous owner has already gotten himself another drive, and he felt that he didn't have any use for this faulty floppy drive anymore. As it turned out, there wasn't really any problem with the write protection functionality, but there was another problem with the drive instead. I took a look at the drive and found out that it was a very simple thing to repair. In the video, I'm testing the disk drive as far as I can using the drive tester program. It's of course possible to perform even more extensive tests, but that requires the use of test gear like an oscilloscope for example, which is way beyond what was needed in order to have this floppy drive fully working again. I would say that this type of failure is one of the most common ones on 3.5" floppy drives. And luckily, it's also one of the easiest failures to repair. Again, this is just a documented repair and is therefore not meant to strictly act as a tutorial. This video is also a little bit more off the cuff and more "real time" than most other videos I've posted so far. I've made some cuts to shorten the length of the video a little and remove some unnecessary things I said that really wasn't necessary for the purpose of the repair, but that's about it. As always, comments and questions regarding the repair are always welcome. The test program used in this video can be found on www.aminet.net as "DriveTest.lha".
