Hi all.  I've just built a new pc and everything seems to have gone swimmingly so far, until I plugged a USB 3.0 hard drive into one of the two USB 3.0 ports on the front of the machine.

 

I hear the noise of the hard drive being recognised by Windows 8.1, then again after a few seconds and repeats until i remove the drive.  I noticed in My Computer the drive letter appearing and disappearing.

 

I then plugged the same HDD into a USB 2.0 port alongside the problematic 3.0 ones (the front of the PC has 4x USB ports) and they all recognised and mounted the drive ok.

 

I plugged the same HDD into a USB 3.0 port at the rear of the pc and again, mounted fine.

 

I then plugged an iPhone into the problematic USB 3.0 ports and it mounted fine, as did a USB 3.0 Stick.

 

Finally I plugged in a USB 2.0 HDD into the problem ports and it mounted fine.

 

So it seems one particular drive has an issue with 2 x USB 3.0 ports that I cant replicate with other ports, or hardware I've tried?

 

Any ideas?

Check the front panel connections for the usb 3 ports to make sure they are in the correct location and firmly seated. Next make sure that any driver needed for the usb 3 ports are installed from you mobo's website.

Ill check it when I open the pc up tomorrow, seems weird all other devices are working on those ports, and that hard drive is working in the rear USB 3.0 ports though?

That did the trick! Rearranged the cabling slightly to give a little more slack in the internal USB 3 connector and now the drive stays connected. Thanks!

 

EDIT: Maybe I spoke too soon. While it started connected and I could access it, I can't disconnect it with right click on the USB icon. Windows just reports a problem ejecting the USB mass storage device.  I have no windows open using the HDD so its not being accessed manually.

 

EDIT 2: Now going back to My Computer its behaviour is the same as before. Constantly showing up then disappearing again.

 

Weird, the first time I connected it, it worked.

Try using USBDeview and then locate the particular external drive from list. Right-click the device and choose Disconnect Selected Device. If not, use Uninstall Selected Device then try inserting the card again. If USBDeview requires you to be administrator, relaunch or run again by right-click 'run as administator' in order to complete the steps given. Otherwise, if not resolved then it might be a hardware problem or connection or a driver update install is needed.
