Cluster count too large for FAT32
    Facility: EFI$CP, The OpenVMS EFI Partition Control Program
    Explanation: FAT32 has a capacity limit on the numbers of storage
    allocation units (clusters), and this limit has been reached.
    User Action: You must specify or utilize volumes with a smaller
    cluster required number of clusters; the attempted volume
    structure is beyond the upper limits of FAT32.
