I think what you are suggesting is some sort of thing whereby you could have the USB from HDD into the separate power source and then on from the separate power source to the receiver for the signal. I've never heard of such a thing.
Some external HDDs want a little too much power and/or the USB ports don't provide enough. I have an external HDD which came with a USB cable that has miniUSB on the end that goes into the HDD and two standard USB plugs on the other end (one is looped off the other).
The idea with this is that both of the standard USB plugs provide power, but just one of them carries the signals. Then I just plug both of the standard USB plugs into USB ports on my PC. It does the trick and may solve your problem. If your receiver has two free USB ports you might not even need a separate USB power adapter (these are readily available though - e.g. amzon, ebay.)
