Hello,
I have two problems since I bought my nuc.
I use it with an external USB 3.0 western digital elements 1To disk.
I installed latest Nuc versions software : bios version 28, USB 3.0 controller version 3.0.0.33, up to date windows 7 64 bits,
First problem :
When I switch on NUC with hard disk plugged in : it is not detected (when the NUC boots, the HD led remains on and not blink, and my disk is not available in windows. If I unplug and plug it again, it's still not detected. If I plug an USB 2 key it's OK).
If I restart nuc (with windows menu at the login page) then at the "INTEL NUC" boot screen, led on hard disk blinks and it's now detected an available in windows.
So I always have to switch on and restart my NUC to use my HDD.
I uninstalled USB 3.0 controller : no more problem at boot. My HDD is available just after boot without restarting windows.
So It is not a material failure but probably a driver issue.
This problem doesn't occur with bios version #22.
Second more annoying problem :
Randomly, NUC losses connection with HD. Not only after a sleeping time.
I tried several bios versions, several USB 3.0 controller versions (2.x, 3.x), with no intel USB 3.0 controller (then with default microsoft usb driver I suppose) : the same problem occurs.
I have to unplug and plug the HDD again to see it again.
What can I do ?
I have no more ideas to test...
