This drive has so many errors in MHDD that I can't wait for it to finish scanning. I wanted to recover the data, and I had an identical drive (same controller, same firmware, etc.) that is working. So I tried the other drive's PCB. No help. Same errors, starting at the same points. So I moved the heads. Same problem. The bad drive still gives lots of errors starting at 89MB. So I put the bad drive's heads in the donor drive and it reads fine (7 UNC errors on entire drive).

Anything else I can try? I'm stumped. Bad platter?

Hi,

It is hard to say you have bad media from here. It could also be FW related. Try skipping to greater LBAs with arrow keys to see if there are better areas.
If yes, U will need some spec. prog to save the data, I would probably try to make an image of the partitions needed with some good imaging prog, then try logically recover the data.
The head swapping can easily shorten the lifetime, so it is hard to make good decision in this case.

Talking about arrow keys in MHDD, I have never figured out their purpose while doing SCAN (walk through disk???, how?)

Pepe, are you in the mood to explain?
