 I’ve spent all day wiping the hard drive,installing Windows Home 32Bit (after having other problems with last O.S.) installed all the MSI Utilites,drivers,software and hardware,then I shut-down,and hooked up my SATA WD 500GB HDD. I looked in the BIOS and it showed both drives…74GB Raptor Sata5, and WD 500GB Sata 6 in the Bios.

I went to hardware wizard clicked on “already installed hardware” and chose WD500 GB HDD, it said it was working perfectly/

I then went into DEVICE MANAGER and saw the two drives in DISK DRIVES, but when I go into the Windows Explorer Folder and look under MY COMPUTER, all I see is the one 74GB raptor,where allmy apps are on.  I need this 500GB for storage. I must have a brainfart and too tired to realizre if I missed a step in installing this second HDD.  Please Help.  Thanks!

Have you tried a different data cable and/or have you tried disconnecting & reconnecting the one that you have?

A cable’s metal contacts can become oxidided thus forming an intermittant resistance to the proper flow of electricity.

'Same approach for trouble-shooting misbahaving RAM and expansion cards: remove & re-seat them.
