I've only gone back a few weeks to get the list started and will try to post more as they roll through. Feel free to add to my list.

Thanks for sharing these, Luke. Seems recovery from DM drives is not as hopeless as generally believed/claimed.

Great Job.

But can you also share the difficulties/problems of head swap?

I believe I've read that finding a compatible donor is especially problematic, that you can't just select a donor based on traditional label-printed parameters (plus head map). Is that true? Any insights to share?

There were no problems with the heads swaps. Matched model, serial, p/n and site, changed the heads, move adaptives (if needed) and clone.

I agree. Compatibility isn't so much the issue as much as heads actually surviving the swap / first power on. I've had a few where as many times as I replaced the heads it would ID one time, work for a couple minutes, then go right back to the click of death. Seems the heads are just uber delicate ( which may explain the high failure rates as well).

Though there do seem to be more cases popping up now with media cache and other firmware issues. So perhaps as they are aging more are failing gracefully instead of catastrophically.

Who knows, a few years from now these may be the cash cows that feed us all.
