SYMPTOMS
You may receive the following error message when rebuilding a catalog using Microsoft Backup for Windows (MWBACKUP.EXE) if you are using the last disk of the backup set to rebuild the catalog.

Invalid Volume Information Block Detected. The component cannot be used.



CAUSE
This error message may occur if the backup set was created using the BACKUP command from a version of MS-DOS earlier than 6.0.



WORKAROUND
To correctly restore the backup set, you must use the RESTORE.EXE command from MS-DOS versions 6.0 and later. For information on using RESTORE, type help restore at an MS-DOS command prompt.



MORE INFORMATION
This error is not generated when using MS-DOS versions 6.0 and later Microsoft Backup for MS-DOS (MSBACKUP.EXE) to rebuild the catalog. Backup for MS-DOS correctly determines that the backup set was created using the previous MS-DOS BACKUP command and displays the appropriate error message. Also, if any disk other than the last disk is used to rebuild the catalog in Backup for Windows, then it too correctly determines that the backup set was created using a previous MS-DOS BACKUP command and displays the appropriate error message.

Additional query words: 6.00, 6.20, 6.21, 6.22 BACKUP.EXE
