It's not in disk management, or on the explorer tree, or in "my computer" It is shown in Bios, and just to be save I reloaded the drivers. Also, I've reset the BIOS, Sata is still there on sata 1 where I it was before. I had it running on idle, but unplugged from the data cable until I cloned tonight, so I don't know if maybe I lost it earlier? Fortunately I did a non destructive clone... It seems to have cloned OK because the windows screen briefly showed up with a flash of a BSOD, both in normal and safe mode. Ideas?
