我的一个磁盘在断电后损坏了。当我尝试通过 fsck 修复磁盘时。首先，它输出“正在恢复日志”和“无论如何运行日志<y>？
按 y 后，fsck 输出：
fsck.ext4: Invalid argument while trying to open /dev/sda
当我检查 fdisk -l 时磁盘消失。
我已经尝试了很多次，重新启动后，磁盘将出现，fsck将开始恢复日志，在我按y后，磁盘就消失了。
对于我的情况有什么有用的建议吗？
以下是一些详细输出：
(anaconda3) ubuntu@ubuntu:/$ sudo fsck /dev/sda
fsck from util-linux 2.27.1
e2fsck 1.42.13 (17-May-2015)
/dev/sda: recovering journal
Superblock needs_recovery flag is clear, but journal has data.
Run journal anyway<y>? yes
fsck.ext4: Invalid argument while trying to open /dev/sda
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>
更新：sda的smartctl的输出：

答案1
几乎可以肯定 上没有直接的文件系统/dev/sda。在你惊慌之前继续阅读。
通常磁盘上有一个分区表，一个或多个分区包含文件系统。此命令将显示磁盘上的分区：
parted /dev/sda --align 最佳单位 MiB 打印
就我而言，我只有一个，在/dev/sda1.注意后面的数字。
Number Start End Size Type File system Flags
1 1.00MiB 49152MiB 49151MiB primary ext4
如果您确实需要这样做，您现在可以fsck在该分区上运行，但您不需要这样做。
e2fsck /dev/sda1
然而，在你运行任何这个之前，更新您的问题以显示磁盘故障的症状，使您相信您根本需要执行此操作。对于某些磁盘故障模式，唯一正确的响应是在磁盘完全故障之前复制磁盘。理想情况下，您将能够运行 SMART 诊断，并使用以下输出更新您的问题：
smartctl -a /dev/sda
