SYMPTOMS
If you use the /Q switch to quick format a floppy disk that was used to store backup files created by Microsoft Backup (MSBACKUP.EXE or MWBACKUP.EXE), you may receive the following error message:

Insufficient space for the MIRROR image file.

There was an error creating the format recovery file.

This disk cannot be unformatted.

Proceed with Format (Y/N)?



CAUSE
This error is generated because FORMAT cannot find enough space to create the mirror image file. If you choose Y to proceed, FORMAT formats the disk without saving any mirror information.



WORKAROUND
When Microsoft Backup uses more than one disk, it always uses the entire contents of the disk. To avoid this error, use the following command:

format /q /u :

The /U switch instructs FORMAT to perform an unconditional format of the floppy disk and saves no mirror information.

If the disk still cannot be quick formatted, use DELTREE to delete the backup file on the disk. For example, type deltree a:\*.* at the MS-DOS command prompt and then press ENTER.
