Yea so I have no clue how to explain the issue, I have a 2013 Seagate Backup Plus 3TB Hard Drive that I use to backup important data I have on a computer, but the problem is that I recently got a new laptop. An Acer Aspire F 15 F5-573-725L and the External Hard Drive doesn't work unless I plug in it into my 4-port USB 3.0 Hub even though I plug it in into a USB 3.0 drive. My previous laptop I was using was a Samsung Chronos Series 7 laptop back in September 2012 and I don't need a USB hub to plug it in into the laptop and same as a iMac 2011. I tried replacing the USB 3.0 cable, but the best I got was that it could read it for a second and then disappear. So I honestly have no clue how to fix this issue with my current laptop. Could it be the laptop? The USB 3.0 cable? the external hard drive itself? I have no clue. please help.
