You may need to install a second OS on that SATA drive then you can "mount" files to it. See "help and support" in "disk management" for information about "mounting" files to a drive.
The setup I was running was 2 IDE HDs with 2 DVD drives. Recently I bought a SATA drive to add since my board also has 2 SATA connectors. When I put the SATA drive in the "slave" IDE drive is not longer showing up. I have tried switching it with one of the burners and that doesn't work. If I connect it to the pc with my usb-to-ide cable it works with no problems. I can't figure out what I need to do to be able to run my system with all 3 drives. Any help is appreciated.
