 try red pins first, and if they not work, try yellow pair

Recov servo mean you can not read the platters.

 To fix, I shorted the PCB to get terminal access...drive still was BSY. Then, forced my way to edit model 93, uncheck all boxes and saved to the drive.

Drive would still read very slowly (about 1MB/second most of the time), with errors. It was definitely at the end of its life. But, we were able to target the data with DDI and mirror only the used data sectors, getting a full 100% clean recovery of the user's data.
