I have a DVD problem, but different from IndyGunFreak's in that I can't remove a DVD drive. XP won't boot if I remove one, or both, of the DVD drives plugged into the secondary IDE controller. This one really has me stumped. The setup: MSI Neo 4 Platinum motherboard AMD 64bit 3700+ CPU 2gigs RAM NVIDIA GeForce 9800 GTX+ video adapter XP Pro SP3 C: - IDE primary, OS and boot D: - IDE secondary, master, DVD SL burner E: - IDE secondary, slave, DVD DL burner F: - SATA Raid 0 - striped drive for games, game maps, CAD files G: - SATA Blu-Ray burner (UDF 2.5 drivers installed so XP can read the Blu-Ray disk format using Explorer). I have a DVD drive with problems (tray won't open, then it won't close, etc) in another PC so I thought I'd remove one of the DVD drives in this system and replace the failing one in the other PC. I really don't need three optical drives in this XP box anyway. That's when the problem appeared. If I remove either D: or E: XP will hang and won't finish booting. Normally I get the XP splash screen with the scrolling blue dots, then a black screen for a second with a cursor/hourglass in the center, then the XP screen comes back and it continues on. With either of the DVD drives removed it hangs at the black screen, forever. The SATA Blu-Ray drive has no effect, it can be connected or not connected and the system boots up fine. I spent about three hours yesterday trying every possible configuration of slave/master, using both jumpers and cable select, or even no drives at all on the secondary controller and it won't finish booting if I make any change to the current setup. I changed the BIOS so boot order is hard drive, USB, Floppy, with no CD to make sure it wasn't looking at the drives at boot time. But it will only boot with the SL drive as master (D), and the DL drive as slave (E) otherwise it hangs on the black screen. I can't remove either one, both, or even swap them as far as slave and master. I'm stuck, anybody have any ideas?
