Accidental double post

That would explain module 02 byte being zero. And with module 32 in the condition it is in, the byte the patch uses to find the starting point to clear the data was 0, so it would have tried to wipe the entire module including all of the header, and the drive would reject that write as the module id would have been zero in the header.

But both patches do make backups of the original dumps, as long as one keeps them (and in the case of running from a live CD, makes a copy to an external drive before rebooting).

The RE-LO is cleared in an aggressive way. HDDSuperTool did not do that, at least not with provided scripts.

Well this had an unexpected resolution. I took the USB board to an electronics repair place to swap the U12 chip onto the SATA board 771692. When I got it back, the drive wouldn't spin up. So I took it back to have them check the soldering and they said it was all done correctly but the drive still wouldn't spin. So I abandoned that plan, and using the ROM I had downloaded from the USB board, I contacted one of the dedicated PCB suppliers and asked if they could supply a 771692 and I would email them the ROM so they could upload it to the board. They said yep no problem, so I did that I just received the board. I reconnected it to the drive, and hooked it up to a machine and booted up Ubuntu. I wanted to see if I could still access the firmware in HDDSupertool as I had been able with the original board.

Low and behold it shows up a disk in the column on the left. I click on it and it mounts and all the data is accessible. Somehow simply replacing the board (or changing it to SATA) restored sector access. Can anyone think of the issue that could have caused that?

I was pretty clear to them about the U12 and getting the orientation right, but something must have gone wrong in the process. Anway alls well that ends well, many thanks for all your help!
