wonder if anyone can help, my optical drive (DVD-RW) has vanished from my computer, device manager, etc, the IDE and power cable are both securely in, the IDE is securely in the motherboard i did however install a second hard disk in RAID 0, can that have anything to do with it, motherboard is gigabyte P35-DS3R and the hard disks are plugged into the gigabyte SATA2 0 and 1 if that makes any difference, thanks for any help
