Before having applied power, you might have wanted to look up some 
components and buzzed which of the pins that the power pins went to, or 
looked at any voltage conversion tanks for clues to the supply in and 
outputs before applying power in any way.  It might just be that Molex 
had cheap connectors that week, and you fried the thing completely 
(sorry to be down, but it is a common connector)

Hopefully it is just that it needs the extra voltage.  Weren't some of 
the 8" drives triple voltage?  it might have 5, 12, and 24 on 4 pins as 
another guess.
