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!

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!

I just checked and my USB 3.0 flash drive is recognized and works fine when plugged to a USB 3.0 port.

Thanks!

Edit: Nobody? Please I need help :(

I have the same problem, my USB 3.0 ports don;t see my USB 3.0 flash drive, but USB 2.0 see it good. USB 3.0 ports working with other devices like keyboard and mouse. If the flash drive in USB 3.0 port I can also see it in BIOS.
