drive error reading FAT sector sector, attempting retry

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

    Explanation: this message reports a device error reading the
    File Allocation Table (FAT). This is ominous. If multiple copies
    of the FAT are present, there will be an attempt to read the
    required FAT data from the same sector within an another copy of
    the FAT.

    User Action: Attempt to copy all user data off the FAT volume, as
    it appears the FAT volume is failing.
