Proliantサーバーに接続されているUSB SATAドックに4つのドライブ（2x3TB、1x4TB、1x18TB）があります。最後に、HBAがIBMディスクアレイを認識し、Ubuntu Server 22.04でドライブが認識されるようになりました。問題は、ドライブをマウントしようとするとファイルシステムエラーが発生することです。彼らはすべてデータを持っており、私はそれを失いたくありません。このドライブには、過去4年間の完全なコーディング記録だけでなく、すべての音楽制作物（ステム、オリジナルCubaseプロジェクトファイルなど）と家族の写真も保存されています。
私はプロのメニューを試しgdisk /dev/sdbてxみましたが、成功しませんでした。以下は出力です。これらのパーティションテーブルを変更してドライブを再マウントする方法についてのアイデアはありますか？ve-v

GPT fdisk (gdisk) version 1.0.8
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!
Main header: OK
Backup header: ERROR
Main partition table: OK
Backup partition table: ERROR
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.

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 5860467632 sectors, needs to be 5860533168 sectors.)
The 'e' option on the experts' menu may fix this problem.
Warning: There is a gap between the main partition table (ending sector 33)
and the first usable sector (65535). This is helpful in some exotic configurations,
but is unusual. The util-linux fdisk program often creates disks like this.
Using 'j' on the experts' menu can adjust this gap.
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 5860467632 sectors.
The 'e' option on the experts' menu will probably fix this problem
Problem: partition 1 is too big for the disk.
Caution: Partition 1 doesn't begin on a 8-sector boundary. This may
result in degraded performance on some modern (2009 and later) hard disks.
