invalid FAT32 volume cluster factor
Facility: EFI$CP, The OpenVMS EFI Partition Control Program
Explanation: Per EFI FAT specifications, no FAT32 volume can
offer less than 65525 clusters, and this volume is outside the
valid range. The FAT volume is apparently corrupted.
User Action: Reinitialize the FAT32 volume with a smaller
cluster size; with a cluster factor within the required range,
or reinitialize the volume using FAT12 or FAT16.
