my vantec nexstar hard drive enclosure (NST-350) power supply died so i cut the cord and attached a molex connecter so that i could plug it in to my computers power supply.
wiring from nexstar is white = +12v
green = +5v
black = ground
bare wire = ground
molex wiring is yellow = +12v
red = +5v
black = ground
black = ground
hope this helps someone else
also found WD external drive pin out. There are 3 wires on the WD cable:
1 with a solid white stripe (+12)
1 with a dashed white stripe (+5v)
1 solid black ( ground )
