This is a Dell PowerEdge T110 II computer.
The chipset is Intel C202.
The original HDD that I removed is WD5003ABYX
The new HDD that I installed is WD5000AZLX ( I aslo tried a new WD 1TB Blue drive).
Both of the new drives are seen as SSD drives in the system.
Not seen in Windows Computer Manage / Storage at all!
I have jumpered pins 5 and 6 on the WD5000AZLX but it made no difference.
