I am using a Fujitsu Lifebook that is 3 or so years old. When I bought it USB 3 was fairly new so perhaps this is why I have the problem I am having. The PC came with 2 USB 2 and 2 USB 3 ports. When I use the USB 3 ports I can hear background sounds of the PC working through the speakers. There is no background sound when I use the USB 2 ports. Because of this I have the drive with my music files plugged into a USB 2 port (its very irritating to hear the background noise when listening to a song when the drive is plugged into the USB 3 port). Can I fix this via a software fix or would I need to do a hardware upgrade?
