attempting to read FAT table table sector sector

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

    Explanation: this message is usually reported in conjunction
    with other messages, and is typically displayed when there are
    errors reading the File Allocation Table (FAT). These errors are
    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. (The FAT table display is
    zero-based, and the sector display is the relative sector within
    the FAT.)

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