Lacie External DVD-RW Power Supply

[kearneyc]

Hi guys,

I purchased a Lacie External USB DVD-RW with no power supply. I am able to build a power supply to run this unit, but am unable to find the voltage requirements and pin assignments. I have been able to ascertain the ground pin connections but not the other two pins. Anyone who may be able to help, please have a look at www.megavolt.bravehost.com, for a diagram of the power supply plug. The model is Lacie DVD±RW DL Designed by F.A Porsche

If you have a unit like this, and are able to measure the voltage with a multimeter, could you please let me know the voltages present at the two pins, with reference to the two ground pins.

Thanks in advance for any help that can be given,
Chris
