Bizarre speculation:
Since most 8" drives use 24V, is there a possibility that this is a 5v&12V
drive design, with the 7812 there to adapt it to 24V?

Is there ANYTHING on the drive connected to that pin of the connector that
does NOT go through the 7812?  If not, could you feed it relatively clean
12V downstream from the 7812?
