1. The drive has no way I know of to make ac hum. If you've the same drive as the rest of us, it sends a signal via the usb to the line out. Do mp3's or cd's have hum?

2. If you are using a laptop and you run off batteries does it go away? If so it's the laptop, and was a common problem.

Radio Shack used to sell a device to eliminate hum. If it is coming from your setup.
