I just bought a used Z800. It came with one drive installed in one of the bays for optical drives, etc. Nothing in the raid trays.
I want to put drives in the RAID trays and use those for file storage. I do not want to lose the programs and OS on the exsting drive. When I intall the drives in the trays and go into teh BIOS, it says "all data will be lost". I am not sure if that means only the drives in the trays or all the drives... including the one drive that has the OS and all my programs.
