Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.
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!
