Sabertooth 990fx and WD20EARS

[PetrAly]

I have new computer:
MOBO - ASUS Sabertooth 990FX
Graph. - ASUS EAH6950 DCII/2DI4S/2GD5, 2GB DDR5, 2×DVI, 4×DP, PCI-Express
Proc. - AMD PHENOM II 1100T
RAM - ADATA 2x4GB DDR3 1600 MHz CL9
SSD Disk - ADATA SSD S510 120GB SATA3/600, MLC


Everything was perfect (for two weeks) until I connected HDD 2 TB Western Digital WD20EARS.
After plugging this HDD to SATA6g (SATA3), I cannot even get to BIOS.
After JMB screen everything went dark and I cannot see even POST screen. On motherboard one LED diod lights until I shut down the computer - BOOT DEVICE LED.

JMB did not find any disk until I plugged this to SATA3g - SATAII connector. But problem still remains...

I fixxed this problem after two days of hard work

I unplugged this HDD, try another HDD and everything worked...
I found out in internet that this HDD did not work properly with ASUS motherboards until new BIOS updates

But new SABERTOOTH 990FX BIOS version 0813 from 17.11.2011 did not work.

Clearance of RTC RAM have same negative result :-(

So I visit BIOS and I cancel one function: JMB Storage OPROM.
I plugged again my HDD and after this the HDD cannot be found by BIOS...
But in my Windows 7 I can normally used this hard drive!!

Ufff....
