Example Case: Stiction

This drive had stiction; the read/write elements and sliders on the original head stack are completely destroyed.

After successfully replacing the MHA with parts from a compatible donor drive, the drive was able to spin up. It comes ready and we get a full ID.

The drive reads quite slowly, after some time it gets stuck BSY, stops IDing and we no longer have SA or DA access. Resolved by uploading a compatible module 11 to RAM - the drive still runs slow but is able to read.

Edited head map in RAM, enabling just H0 and H1 to read SA modules. Built a complete module 11 from copies with bad regions. Disabling bad heads allows DE to build it's head map OK, then can revert to default head map in RAM.

H1 and H3 are good, imaged all the data on these.

H0 and H2 are weak and have a lot of bad regions, so imaging is slow.
