unrecognized FAT12 floppy disk volume geometry detected Facility: EFI$CP, The OpenVMS EFI Partition Control Program Explanation: One or more of the FAT12 volume structure checks has detected a volume geometry that is not recognized, as EFI$CP supports only a subset of the available FAT12 floppy disk devices. User Action: FAT12 volumes have predesignated geometries, and this FAT12 volume has an unrecognized geometry. Repair or reinitialize the target volume appropriately, or transfer the contents of the FAT volume onto one of the recognized and supported FAT volume formats (and the associated geometry). The 2HD 1.44 megabyte RX26 floppy disk drive is the most common floppy disk typically found on OpenVMS systems.
