你好世界，
我是阿什温寻求帮助，在我的 Ubuntu 系统上恢复和安装加密的外部硬盘。情况如下：
背景：我最近尝试使用 LUKS 加密方法加密我的外部硬盘，这是从旧笔记本电脑中取出的西部数据硬盘，方法如下：RedHat 的网站。加密之前，我能够通过 /media 文件夹安装和使用该驱动器。
问题：加密后，驱动器停止安装，尽管连接时它会提示我输入密码来解锁。
解密尝试： 解决安装问题后，我解密了驱动器，但问题仍然存在。
重要信息：
以下是 的输出lsblk：

这意味着它检测到我的驱动器，但不允许我使用主分区
另外，运行fsck /dev/sda3会出现以下错误：
fsck from util-linux 2.37.2
e2fsck 1.46.5 (30-Dec-2021)
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/sda3
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>
Found a dos partition table in /dev/sda3
要求： 我需要帮助来恢复和安装加密的外部硬盘，且不丢失任何数据。分配的数据尚未被覆盖。
笔记：
我在整个过程中一直使用 sudo。所有数据都需要安全地检索，不能有任何损坏或丢失。我很感激任何有关此事的指导或帮助。谢谢！
编辑：
在我昨天拔掉电源之前，我一直在关注lsblk
