我有一个小问题，我的家庭服务器没有安装我的 3TB GPT。昨天一切都很好，今天早上我意识到我无法进入我的网络存储。起初我认为这是一个网络问题，但现在我意识到我的硬盘没有安装在服务器上。
HDD 是半年前使用的 3TB WD NAS 驱动器，带有 EXT4 分区 在我通过 CLI 连接到我的服务器后，我无法安装 HDD：
mount /dev/sda1 /media/test
mount: special device /dev/sda1 does not exist
所以在此之后我检查了 gdisk
gdisk -p /dev/sda
Disk /dev/sda: 5860533168 sectors, 2.7 TiB
Logical sector size: 512 bytes
Disk identifier (GUID): 39C0E260-042B-49D4-8E6E-9BC50D737FD2
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 5860533134
Partitions will be aligned on 2048-sector boundaries
Total free space is 2014 sectors (1007.0 KiB)
Number Start (sector) End (sector) Size Code Name
1 2048 5860533134 2.7 TiB 8300
看来分区是有的。
但现在 dmesg 让我震惊了：
dmesg | grep sda

我可以做些什么来恢复硬盘，或者其他一些提示和技巧？
谢谢您的帮助
