SYMPTOMS
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.
CAUSE
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.

After you install this hotfix, you must create a registry key value for the 1394 drive to enable the fix that resolves this problem. WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.

- Start Registry Editor (Regedit.exe).
- Locate and click the following key in the registry:
HKEY_LOCAL_MACHINE\Enum\Scsi\_1394_device_subkey_
To determine the correct registry key, examine the DeviceDesc value in each registry key. The correct registry key has a DeviceDesc value that contains the name of the affected IEEE 1394 drive, as displayed in Device Manager, for example:HKEY_LOCAL_MACHINE\Enum\Scsi\Pioneer_DVD-RW__DVR-103_1\Sbp2&sony&pcva-drw1&lun0&0800460300252a2200 - On the Edit menu, click Add Value, and then add the following registry value:
Value name: Enable Q304708
Data type: Binary
Value data: 01 - Quit Registry Editor.
