我的台式电脑断电了，开机后一个硬盘出现了一些错误。GUI 上没有显示该硬盘。在终端上，我收到此错误：
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdc, missing codepage or helper program, or other error.
lsblk -l 仅显示 /dev/sdc
fdisk -l

Disk /dev/sdc: 3001GB
Sector size (logical/physical): 512B/4096B
Partition Table: unknown
Disk Flags:
gdisk -l /dev/sdc
GPT fdisk (gdisk) version 1.0.3
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.

有没有什么好的办法可以修复这个硬盘？！这个硬盘上只有一个分区，数据最好不要丢失！
