    I have some HGST Ultrastar SSD800MM SAS3 Enterprise SSD with EMC firmware
    Code:
    /dev/sg4  0 0 3 0  0  /dev/sdc  HITACHI   HUSMM808 CLAR800  C210
    

    Here is what I see with gdisk
    Code:
    # gdisk /dev/sdb
    GPT fdisk (gdisk) version 0.8.6
    Problem reading disk in BasicMBRData::ReadMBRData()!
    Warning! Read error 22; strange behavior now likely!
    Warning! Read error 22; strange behavior now likely!
    Partition table scan:
      MBR: MBR only
      BSD: not present
      APM: not present
      GPT: not present

    This is the output of the verify
    Code:
    Command (? for help): v
    Problem: Disk is too small to hold all the data!
    (Disk size is 0 sectors, needs to be 0 sectors.)
    The 'e' option on the experts' menu may fix this problem.
    Problem: GPT claims the disk is larger than it is! (Claimed last usable
    sector is 18446744073709551582, but backup header is at
    18446744073709551615 and disk size is 0 sectors.
    The 'e' option on the experts' menu will probably fix this problem
    Identified 2 problems!

    Of course the 'e' option does not help at all.

    Basically I can't do anything because the disk has 0 sectors... o_O
    Any idea how to fix this?
    I have asked to Western Digital Support if they can provide me an original HGST firmware but I have zero faith that they will...
