Here is a thread from a few years ago in which MLA user Charadis does a teardown of a Rev. C module, the most useful module, since it is compatible with Wifi PC cards: https://68kmla.org/bb/index.php?threads/powerbook-500-series-pcmcia-module-rev-c-teardown.30745/

I've watched how to make a clean box in the past, and while it's certainly intriguing, it's not something I currently need right now as I'm not doing this nearly enough. But it would be a really good idea if I were to suddenly end up with a precious drive in need of recovery!

The only "website" for the AirTalk (that I'm aware of) is that original thread. If you're interested, you can leave a response to that thread, or your can DM cheesestraws directly via 68kMLA.

I will say, I had cleaned the top platter with IPA after contaminating it at one point in the restoration process. It left behind streaks (which are still there, even now that it's functioning). At one point before it began working, I had gently buffed with a microfiber cloth a small spot near...

For funsies, some footage of the drive functioning normally (mostly, till the end) from when it first started to go again:

Incredible:

Was able to copy the entire drive! Now that that's done, I will try making a proper disk image. I guess the hard drive was able to recover itself somehow with enough power cycles? EDIT: And success! Now running Disk Doctor on the drive... (Not that I expect to use this drive in the long term...)

Well lookee here! Gonna try restarting with an external to make a backup...

There are three small caps on the controller board, as you can see. I suppose they could be replaced, but that seems unlikely to be the issue, since it is still doing something.

I did not have to remove the platters at all.

As mentioned, I used electrical tape on the bumpers.

And the underside of the controller board:

Here's a photo of the underside. Looks okay to me at a glance.

How's this? Also exhibiting a new behavior. (The clacking is the arm knocking into the PLCC.)

I decided to take another video and just upload to YouTube. Here's the video:

Thanks for the reply, but as already stated, I've already dealt with the stiction and the arm is moving freely, so I know that's not the issue. Since I can't seem to upload the video I took, the arm performs a smooth but narrow scanning motion for a bit, then attempts a seek (or some other...

Hello, I'm currently trying to resurrect a Quantum ProDrive 80S that came with a Mac II I bought recently. The drive itself is not actually important to me, and so this is more of a technical challenge than anything else. I've already dealt with the arm stiction by applying some electrical...

Wonderful utility! Any chance of it working with Disk Copy 6 NDIF images in the future?

A Plus, especially a later one which has better components on the analogue board, is pretty reliable, especially if you can get a fan attachment, or mod one in. If you have an earlier Plus, and it's otherwise functioning, I highly recommend following the guidance in Macintosh Repair & Upgrade...
