asus g75vw 32 gb ram 256 ssd running windows tech preview build 9879 second hard drive the original 750 gb I see in disk management as unallocated. After formatting it shows up in windows explorer with its full volume. When I reboot it disappears. When I go back to disk manager in says it needs to be initialized when I go to do that choose gpt and it says partition to small. If I choose MBR I get an I/O error.
