Bad 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 too old. 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.
