Hi AxshunJaxun
thanks for reply, my BIOS version is F.27. Driver version for WD HDD is the last one, I had checked it and reinstalled a few times, there is no yellow triangel in device manager. BTW after I connect HDD I am not able to use driver upgrade due to there is reply from manager due to it tries to read CD partition on WD, then I am not able to even restart laptop, it is running a kind of inner aplication.
