Command (? for help): ^CBackups-MacBook-Pro:~ backup$ sudo gdisk /dev/disk0
Password:
GPT fdisk (gdisk) version 1.0.1
Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.
Caution! After loading partitions, the CRC doesn't check out!
Warning! Main and backup partition tables differ! Use the 'c' and 'e' options
on the recovery & transformation menu to examine the two tables.
Warning! One or more CRCs don't match. You should repair the disk!
Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: damaged
Found valid MBR and corrupt GPT. Which do you want to use? (Using the
GPT MAY permit recovery of GPT data.)
1 - MBR
2 - GPT
3 - Create blank GPT
Your answer: 2
Warning! Main partition table overlaps the first partition by 34 blocks!
You will need to delete this partition or resize it in another utility.
Warning! Secondary partition table overlaps the last partition by
4613656342287257470 blocks!
You will need to delete this partition or resize it in another utility.
