Hi Kevin,
When windows is already up and I plug the Hdd, the Hdd is not recognized. I'm obliged to restart windows for that the Hdd is recognized.
I have tested the new firmware from WD, there is no change.
With the previous BIOS 26, l had no issue.
It work perfectly before and I tested my USB key and I have the same issue. Also my keyboard, I can't acces to the BIOS with F2 key but work when windows startup.
Thanks for your answer.
