unexpected GPT bootblock data structure version detected

    Facility: EFI$CP, The OpenVMS EFI Partition Control Program

    Explanation: The specified bootblock contains what appear to be
    GPT data structures, but the data structure version code is not
    one that was expected.

    User Action: The command or request may not be able to operate
    as requested. If the target volume contains valid GPT structures,
    then the version of this tool is apparently incompatible with
    that of the target structures. Depending on the context, the
    utility may attempt to continue processing.
