HDD 未被正确识别

直到几次重启之前，我的 500GB 硬盘运行正常。

lsblk

sdc1 是我想要的。

然而，尝试安装它

sudo mount -t /dev/sdc1 /media/usr/HDD2

给出

mount: can't find /media/usr/HDD2 in /etc/fstab

所以我跑

blkid /dev/sdc1

得出

/dev/sdc1: PARTUUID="0000814a-01"

sudo fdisk -l 也没有提供更多信息

Disk /dev/sdc: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes

但它肯定被系统识别了（截图链接）

所以我迷路了。

编辑1：

ls /media/usr

HDD2 HDD1 My Passport extHDD

然后

sudo nano /etc/fstab

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name   #devices
#that works even if disks are added and removed. See fstab(5).

sudo fsck /dev/sdc1


fsck from util-linux 2.26.2
e2fsck 1.42.12 (29-Aug-2014)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdc1

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
 or
    e2fsck -b 32768 <device>

是的，看起来磁盘已损坏。如果之前可以正常工作，则可能可以恢复它，并且可能如 @psusi 所建议的那样，运行testdisk可能会完成这项工作。

sudo apt-get 安装 testdisk

然后

sudo 测试磁盘 /dev/sdc1

我没有坏掉的磁盘来测试它，我也不知道它会对你造成什么影响，但它宣称自己可以检查和恢复丢失的分区，至少听起来是对的。祝你好运。
