There is a big difference between what third party software's can see and what the manufacturer's diagnostic can see.

If third party diagnostics cannot see it, well a number of items can be defective. If the manufacturer's diagnostic cannot see it, then its PC board is defective or motherboard line drivers have failed.

Not specifically stated - does its disk platter spin up?
