SYMPTOMS

If you have two removable media in the computer (for example, floppy disks or magneto-optical media) that have non-unique volume serial numbers and similar files, you may receive the following error message:

STOP 0x00000023 (Parameter1, Parameter2, Parameter3, Parameter4)

Back to the top

CAUSE

This behavior occurs because the FAT file system driver recognizes the two media as being identical. However, because there are some differences between them, you receive an error message.
