Hi,
Normally I'd try quite a bit myself before posting here but I'm afraid to try much since data is on the line. As far as I can tell this seems to be a software issue rather than a hardware problem, though I can't be 100% sure. I say this because both drives involved are fairly new, still...
I unplugged all the wires from the back of my computer to clean it and when I plugged everything back in the speakers are not working. Is there a specific spot that they need to be in or can they be in any usb port?
