If it's anything like the Sony MP-F63W-72D for the 1000HX, the pin out
is the same as a regular floppy except for the pins expecting the
power.  The power pins are using what on a regular floppy are the
signal ground pins.

Tracing the connections:
3,5,7,9,11 = +5v
13,15,17,19,21,23,25, 27 = power ground
29,31,33 = +12v
