I recently got a Seagate 4TB Expansion Desktop drive (USB 3.0) that requires an external power source. I'm not quite sure what the voltage is, but I could look if needed. Is there some sort of cord that on one end has a USB plug and on the other has a power supply plug (the round one that goes into the hard drive)? I'd really like to eliminate the external power supply and just use that kind of cord I mentioned to just plug it in to my laptop - one USB for data transfer and one for power supply.

A 3.5" 4TB drive requires more power than a USB port (or two) can provide.

A USB port cannot provide enough power for that drive.
That which you linked will only work with a Buffalo drive (i think).

Good point. But do you see any other solution? Like maybe a cord that plugs into the power supply of the hard drive and splits into two USB cables or something which both plug in to the laptop?
