Hi,
Since I Update my NUC with the last bios driver (0027), my external HDD (WD My Passport Ultra 1To) is not recognized by windows 8.1 but when I reboot the NUC, the HDD is recognized by windows. The problem is on all port.
I have to reboot the computer for that the external HDD be recognized by windows.
Sorry for my bad english.
Regards
