IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SYMPTOMS
When you start Microsoft Backup, your computer may stop responding (hang). Or, you may receive the following error message:

Microsoft Backup has encountered a serious error in the Tape Manager. Quit MS BAckup and all other programs then try again. If problem persist, reinstall MS Backup

CAUSE
When you start Backup, it attempts to detect whether the computer contains a tape drive. If Backup incorrectly determines that there is a tape drive when there is not, the computer may hang.

RESOLUTION
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT or Windows 2000, you should also update your Emergency Repair Disk (ERD).

To correct this problem, follow these steps:

 Restart your computer.  Change the value for the TapeDriveDetected key from 1 to 0 in the following registry key:      HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\ Applets\Backup 

NOTE: If you have never run Backup successfully, the Backup key may not exist in the registry. To create this key, restart your computer in Safe mode, run Backup, quit Backup, and then restart your computer normally. You can then follow the steps above.
