BIOS Cannot recognize WD Caviar Green 1TB WD10EADS


May 27, 2012
I have a HP Proliant Microserver AMD N36L with 3 HDs

1X Seagate Barracuda 7200 RPM runing windows home server 2011
2X Western Digital Green Caviar 1TB - WD10EARS with pictures and videos

It was working perfectly with the AMD RAID 1 instaled from de BIOS.

But sudently, after 10 days working, It showed me a Critical Error with one of the Wester DIgital HD.

Since then the Bios cannot recognize my second Wester Digital.

But when I turn off the server for 5 minutes, the problem HD apear in the bios, but not in the OS.

I went to a repair shop and they said the HD was fine, they just formated and made a new partition. But the problem continue.

What should I do? Please Help.

ps. Sorry for my english, I´m from Brazil.
