RAID5 is operating but GPT has CRC error and/or is corrupt (depending on who give the error message).
I have read all of the helps I can find on this and I did what they said and it worked... once only. But for the other 3 disks in the RAID, I also get the same message and gdisk won't fix the other 3. It seems to but there is no change. Even rebooted. Still no change. I get the error from fdisk and gparted.
The primary GPT table is corrupt, but the backup appears OK, so that will be used.

It used to see it for sda, b, c and d. I did the steps with gdisk on sda. No more message. I was happy. Did the same steps on b, c and d and the error does not go away for these three drives.
I really would like to get rid of this and have a healthy and happy drives.
Thanks for any pointers on this beyond the failing gdisk.
