IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base:
256986 Description of the Microsoft Windows Registry

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.

RESOLUTION

A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem.

To resolve this problem, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English-language version of this fix should have the following file attributes or later:
   Date    Time  Version      Size    File name  Operating system
   --------------------------------------------------------------
   8/9/01  7:08  4.90.0.3003  41,643  Cdvsd.vxd  Windows Me

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.
To create a registry key value for the 1394 drive:
1.Start Registry Editor (Regedit.exe).
2.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
3.On the Edit menu, click Add Value, and then add the following registry value:
Value name: Enable Q304708
Data type: Binary
Value data: 01
4.Quit Registry Editor.
