I connected an 8 pin power plug into the 8 pin jumper of the hard drive and turned it on. Is the hard drive shot now?
 
The jumpers are wired to ground and to the I/O pins of the drive's MCU (the largest chip). I expect that the MCU will now be dead, in which case the drive won't spin.

BTW, what kind of "8-pin power plug" are you referring to? A floppy power connector has 4 pins ...
