Question on disc drive encoder

-> This makes me suspect the encoder mechanism. The drive uses an IR
-> emitter/detector through a glass reticule with sector markings
-> on it.

You mean track/cylinder markings, don't you?

-> the encoder was shot, wouldn't that make it hard for the drive
-> to initially seek cylinder 0 upon loading as it does correctly?

Yes. What is curious is that is slowly "steps". For it to step, it must be
discerning the reticule markings.
