我正在尝试做一些我认为相当简单的事情，但它不起作用。我有一个 8TB Easystore，我用它来存储媒体一段时间了（在 Windows 计算机上，它是我的 F:\ 驱动器）。我现在想通过我的 Ubuntu 服务器（Ubuntu Server 16.04 LTS）上的 plex 服务器访问该媒体。我试过了
sudo mount -t ntfs -o nls=utf8,umask=0222 /dev/sdb1 /media/external
但无济于事。它返回
ntfs-3g: Failed to access volume '/dev/sdb1': No such file or directory
ntfs-3g 2015.3.14AR.1 integrated FUSE 28 - Third Generation NTFS Driver

这让我很困惑，而且 fdisk -l 显示
Disk /dev/sdb: 7.3 TiB, 8001562869760 bytes, 15628052480 sectors

关于如何完成这个简单的任务有什么建议吗？
编辑：这是 sudo gdisk /dev/sdb -l 的结果
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: 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 15628052480 sectors, needs to be 15628053168 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 15628053134, but backup header is at
15628053167 and disk size is 15628052480 sectors.
The 'e' option on the experts' menu will probably fix this problem
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.

Caution! Secondary header was placed beyond the disk's limits! Moving the
header, but other problems may occur!
Warning! Secondary partition table overlaps the last partition by
33 blocks!
You will need to delete this partition or resize it in another utility.
