I was using a DPLL. For problem disks, I used measurements from tracks
that read OK to tweak the DPLL parameters for tracks with issues, and
that sometimes helped.
The code was on a hard drive that crashed. :-(
It wasn't very fancy code, and I hadn't spent all that much time on it,
so I don't think it would be all that hard to recreate it.
