If my search for a 400k drive comes up short and/or if time allows later
this week I'll work on seeing if I can ID the motor controller IC.
There are two PCBs in the drive, the top of the platter goes through one,
and the bottom of the platter goes through another. When I open it up
again, I'll take some pictures.

Is there just one PCB in the drive, or is the spindle
motor as separate
board? Can you identify the spindle motor controller IC? If not, what ICs
are on the board (and we'll see if we recognise anyof them)?
