Maybe you want to try interfacing the HDA from a modern drive, with
unknown embedded servo patterns, etc, to the electronics from an ST506. I
don't think that's totally trivial.

OK, I have an ST412 (maybe an ST506, it's one of the early ones) where
the hall effect sensor in the spindle motor has failed. Now, it should be
possible given a moderate clean room to dismantle the heads and platters
(and that's the only way that spindle motor will come out), but then
what? It was put together with a press, there are probably ferrofluid
seals on the shaft, etc. It's not going to be easy to take apart and get
togerther again. I know I don't have the tools to do it.
