How to fix the external drive keeps disconnecting?

I am connecting an external hard drive to read stored data files from it. I am connecting via USB to one of the terminals on the rear of the Mac Mini. My problem is that after about 5 minutes of using this 'connection', I get a message saying that it has been disconnected. The hard drive is still physically connected and powered up but I can no longer see the icon for the external drive within Finder and in order to be able to go back and read files on the external drive again I need to turn it off and turn it on again. I did not have any problems with the external drive before when using a PC. Does anyone know the cause?
