Tak jsem se zkusil prokousat dál, ale bez úspěchu. Zkusil jsem přes gdisk odstranit partition, vytvořit novou se stejným začátkem a poté jsem chtěl opravit backup GPT a zkoušel jsem to i mnoho způsoby v různém pořadí ale nakonec se stejně nepodaří zapsat a ukončit gdisk. Přikládám postup s příkazem verify, kde se dopracuji k nulovým chybám, ale stejnak se nepodaří zapsat a ukončit, už fakt nevím... Omlouvám se za megavýpis, často jsem vypisoval nápovědu, ale aspoň je vidět, co jsem dělal.

root@vmware:~# gdisk /dev/sdc
GPT fdisk (gdisk) version 0.8.1

Warning! Disk size is smaller than the main header indicates! Loading
secondary header from the last sector of the disk! You should use 'v' to
verify disk integrity, and perhaps options on the experts' menu to repair
the disk.
Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.

Warning! One or more CRCs don't match. You should repair the disk!

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: damaged

****************************************************************************
Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk
verification and recovery are STRONGLY recommended.

Command (? for help): v

Caution: The CRC for the backup partition table is invalid. This table may
be corrupt. This program will automatically create a new backup partition
table when you save your partitions.

Problem: The secondary header's self-pointer indicates that it doesn't reside
at the end of the disk. If you've added a disk to a RAID array, use the 'e'
option on the experts' menu to adjust the secondary header's and partition
table's locations.

Problem: Disk is too small to hold all the data!
(Disk size is 5860531055 sectors, needs to be 5860533168 sectors.)
The 'e' option on the experts' menu may fix this problem.

Problem: partition 1 is too big for the disk.

Problem: partition 1 is too big for the disk.

Warning! Secondary partition table overlaps the last partition by

You will need to delete this partition or resize it in another utility.

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!

Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT).
Warning! An error was reported when writing the partition table! This error
MIGHT be harmless, but you may have trashed the disk!

A prostě to skončí tím, že jsem si mohl po.... disk a konec. Nevím už.
