External 1TB USB 3.0 Hard Drive works perfectly on MAC and PC when using a USB 2.0 port. When plugged into USB 3.0 port on a PC the computer does not recognize it or interface with it.


NOTE: The drive may be recognized as a USB device, but not as a hard drive in Device Manager, and may not show up in Disk Management.


Do additional drivers or software need to be installed to connect to the External Hard Drive through USB 3.0?

A small percentage of computers may require a USB 3.0 "Y" cable for the External USB 3.0 Hard Drive to get enough power.


Some PCs limit the amount of power that can be drawn from a USB port, this can prevent the External USB 3.0 Hard Drive from working properly. The "Y" cable allows the USB 3.0 hard drive to pull power from two ports and get enough power to work properly.


An alternative to a "Y" cable would be a powered USB 3.0 hub (the type that has an AC adapter that plugs into a wall electrical outlet).
