[root@lamachine ~]# gdisk /dev/sdc GPT fdisk (gdisk) version 1.0.1 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: not present BSD: not present APM: not present GPT: damaged Found invalid MBR and corrupt GPT. What do you want to do? (Using the GPT MAY permit recovery of GPT data.) 1 - Use current GPT 2 - Create blank GPT Your answer: 1 Command (? for help): x Expert 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: GPT claims the disk is larger than it is! (Claimed last usable sector is 5860533134, but backup header is at 5860533167 and disk size is 5860531055 sectors. The 'e' option on the experts' menu will probably fix this problem Identified 4 problems!
