Caviar Green WD20EARs-00MVWB0 start and stop

[matinciel]

Hi,

got a problem with a 2TB mentionned disk.

Proc : core i7 920

Motherboard : Asus P6T

RAM : G.Skill - triple channel - 6x2048Mo DDR3 PC12800 - CL9-9-9-24 - 1.5V - F3-12800CL9T-6GBNQ

Windows 7 64bit pro

System drive OCZ Vertex 2 120GB

Power : Seasonic M12-600 V2.0 600 watts

Graphics : GTX275 + GTS250

Other drives:

1x Caviar Green WD20EARs-00MVWB0 start and stop

2x Samsung HD103SJ / HD103UJ

1x Velociraptor 300GB

Problem :

I boot up, no problem I have acces to the caviar green. Then sometimes, the disk shut down (just this one, I don't know if it is realy a shutdown) no more acces to disk.

In disk management the disk disappear.

Right click : rescan disk => sometimes, the disk reappear for a while.

As Liloo said in the fith element : "Please help".

I check Data Lifeguard diag  SMART status PASS

Quick test PASS

Long test : FAIL (too many bad sector but the disk has "shutdown"

Thanks for reading.
