Regarding how much the HD draws, these are the electrical specs: Electrical Specifications Current Requirements External Power Specifications (optional) DC Input Voltage 5 VDC, 1.0A http://www.wdc.com/en/products/products.asp?driveid=261&language=en#jump99 which is funny since you just said that USB2 could only provide 500mA. > > I would be grateful is you do clear me up these details so I can think > > about what to do next. > > Test a USB2 Stick. > > m > Thank you for your explanation. :-) It seems I'm out of luck, no USB2 stick to try this out but I'm pretty sure you're right. Same thing happened to another guy I found online. It seems I could use http://www.wdc.com/en/products/accessories.asp?prodid=170 for this to work but again I'm out of luck since it's out of stock. Oh well, it seems I'll have to be happy with USB1 right now.
