Hello people!

I have a IBM SAS drive, MODEL: HVC103030CSS600, 300GB 10K RPM and he doesnt detect in SAS controler when the drive inicialize. It spins and ear the heads calibrate but he doesn't apear when the controler is detecting before Windows starts.
When we enters in W7 i can see the drive in Winhex but i can't acess it, gives me error. In R-Studio i see the drive but when i try to make a scan the drive doenst let me select any options in the tab...
Anyone have a same problem with this drive? Our know something?
My question is: The problem is in the PCB? our something else?

Thanks in advance experts
