This article was previously published under Q188230

SYMPTOMS

When you view the drives listed in the Drives box in the Drive Converter (FAT32) tool, a 640 megabyte (MB) magneto-optical disk may be listed as a 512MB disk, and if you try to convert this disk to the file allocation table 32 (Fat32) file system, you may be unable to do so.

CAUSE

The behavior occurs because 640MB magneto-optical disks use a non-standard sector size of 2 kilobytes (K).
