SYMPTOMS

When you use the backup program that is included with Windows 2000 (NTBackup.exe) with certain models of USB tape drives, you may not be able to restore backups from the USB tape drive or back up to the drive if the Verify option is turned on.

You may receive one of the following error messages:
  • When you generate a catalog from the tape media:
    Unrecognizable Media
    The media in the drive has an unrecognizable format or is not formatted.
  • When you restore from a backup set:
    Required Media Missing
    The next media required in the active family is not currently on-line.
    Please insert the media:

    Name_of_backup_media, media #0

    or click Cancel to stop the current operation.
    The message is displayed even when the correct media is inserted.

    After you click Cancel:
    Drive Error
    The device reported an error on a request to mount the media.
    Error reported: Unknown error.
    There may be a hardware or media problem.
    Please check the system event log for relevant failures.
  • When you perform a backup operation with the Verify option turned on:
    Backup Utility
    An inconsistency was encountered on the requested media.
  • When you perform a backup operation and append the backup set to existing media:
    Backup Utility
    An inconsistency was encountered on the media in Name_of_drive. Do not append to this media.

CAUSE

This problem occurs if you use NTBackup with USB tape drives that use the USB storage driver (Usbstor.sys).
