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...
