[quote name='watertails']I just got a hard drive ordered on April 17, but I have a question about it. Does it have, like, a secret USB port or something? The cable that came with it is a three-pronged USB, but all I can find on the HDD itself is for DC power adapters and a miniusb port.[/QUOTE]
The cable should have 1 mini-usb for the ext drive, and then 2 normal usb to connect to the computer.
You only need to connect 1 of the normal usb connectors if your computer supplies enough power (i.e. most USB 2.0 ports do). But, if you have problems with the drive not spinning up, try connecting both of the normal USB plugs to the same computer (the second connector is just for the additional power).
