It's funny you should mention this. I've spent the whole weekend trying to do this to my BIL's 7950UB.
He has a 40GB fujitsu HDD in an original transcend casing. The transcend casing works mostly without any external power, just off the USB. However, there is an additional wire supplied with this casing, where one end is USB and the other looks like the end of a power adaptor. On my mac powerbook, I need to use 2 USBs to power it. I'm guessing this is because of the current limiter on the USB port.
The very first time I powered up the 7950UB (At home using a 3A 12V power supply) I connected this casing to it. It spun up perfectly and worked like a dream. Till I disconnected it. After that, no matter how many times I shut down or started, the HDD would go
tick-tick-tick but not spin up fully, indicating a need for more current.
It did the same thing in the car. WOrked perfectly the first time we powered it up. But later, no matter how often we even disconnected the power, it did not spin up again.
The pioneer manual states that it can handle mass storage upto 250GB. It also states that the current limit on the USB port is 500mA. I'm guessing it's wither borderline or insufficient.
I have now found the perfect solution.
I'm going to power up the HDD using a USB cigarette lighter adaptor as well as the USB from the 7950. I am assuming this will work well.
