Before you send it back here is a couple of things to try.

1- If you are using a Window OS go to the device manager, click on Universal Serial Bus Controllers, then from the drop down menu right click on each USB hub/properties/power management and unclick allow the computer to turn off this device etc. With this on (a check mark in the little square) allows the computer to shut off USB ports, thus stopping anything plugged into it to stop working.

2-With a small screwdriver take apart the BiaB external hard drive case. pull out the hard drive then plug it back in and reseal the case. Make sure you do this with the the unit unplugged from the computer. Sometimes the unit gets jarred around during shipping and the drive becomes loose and has a bad connection. I have had to do this a couple of time myself.

I hope this works and good luck.

When you are at the checkout line and they ask if you found everything say "Why, are you hiding stuff?"
