256986 Description of the Microsoft Windows Registry
If you attempt to shut down a computer that is running Windows Millennium Edition (Me) and a Universal Serial Bus (USB) storage device and certain IEEE 1394 digital video disc (DVD) drives are attached to your computer, your computer may stop responding (hang) and your screen may be black or illegible after a delay of 15 seconds or more. If you press a key on the keyboard, your computer may shut down. When you start your computer again, the ScanDisk tool may run.
This problem can occur if an input/output (I/O) request racket is issued for the IEEE 1394 drive after the drive shuts down. Because the drive no longer exists when the I/O request is issued, the packet times out after 15 seconds.
