USB 3.0 HDD not recognized on USB 3.0 port but works fine on USB 2.0 ports Tags: USB3 Storage Windows 8 USB Port Hard Drives Last response: August 27, 2014 4:48 PM in Storage Share Warskin August 27, 2014 10:40:19 AM Hello, Hello, I’m having a problem and I hope I can get some help here. I recently got an external HDD USB 3.0 (Seagate expansion). When I plug it on a USB 3.0 port on my computer, it isn’t being detected by windows 8.1. Disk management doesn’t see it either. My bios detects it as a USB hard drive (after I updated it). The thing is, my HDD is detected without any problem by Windows when it is plugged on a USB 2.0 port. I know my USB 3.0 work fine as they detect USB keys and such. I looked online, did all the tricks with power management and what not, but to no avail. Now, my HDD works on USB 2.0 so I can still use it, but I was looking forward to USB 3.0 speed especially since this is a HDD for backing up pictures and music and stuff… Any help would be greatly appreciated. My hardware details are below. Thanks! __________________ BItfenix Ghost Corsaire 750W PSU Intel Core i5 4430 @ 3GHz Asus Z87-A Kingston Hyper X 12GB DDR3 1600 MHz GTX 550 Ti Win 8.1 64 More about : usb hdd recognized usb port works fine usb ports Reply to Warskin WyomingKnott a c 306 G Storage August 27, 2014 11:27:45 AM Does the USB 3.0 port recognize _any_ USB 3.0 device, or only USB 2.0 devices? That could help us narrow it down. Reply to WyomingKnott m 0 l Warskin August 27, 2014 12:13:06 PM WyomingKnott said:Does the USB 3.0 port recognize _any_ USB 3.0 device, or only USB 2.0 devices? That could help us narrow it down. I'm pretty sure I have tested it with another 3.0 device, but since I have a doubt, I will check again when I get home. I have a USB key that is 3.0. I will report back in a few hours. Thanks! Reply to Warskin m 0 l Can't find your answer ? Ask !
