我删除了驱动器上的文件系统（三年前）。磁盘未格式化，因为我想恢复我的文件并且我没有 Windows/Linux 操作系统。
是否可以不格式化就应用NTFS文件系统？
注 0：
[joseluisbz@centos ~]$ sudo mount -t ntfs /dev/sda2 /run/media/joseluisbz/recover
mount: /run/media/joseluisbz/recover: wrong fs type, bad option, bad superblock on /dev/sda2, missing codepage or helper program, or other error.
[joseluisbz@centos ~]$
这不起作用。
注 1：
[joseluisbz@centos ~]$ sudo fdisk /dev/sda
Welcome to fdisk (util-linux 2.32.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Command (m for help): t
Partition number (1-3, default 3): 2

Changed type of partition 'HPFS/NTFS/exFAT' to 'HPFS/NTFS/exFAT'.
Command (m for help): w
The partition table has been altered.
Syncing disks.
[joseluisbz@centos ~]$
不幸的是，重新加载GParted我得到相同的结果。
笔记2：
[joseluisbz@centos ~]$ sudo gdisk /dev/sda

我下一步需要做什么？
答案1
是的，您可以使用fdisk或gdisk任何其他控制台实用程序，它允许更改分区类型或创建分区而无需实际格式化它。
例如对于 fdisk 它将是：
sudo fdisk /dev/sda
t (change type)
2 (select the second)
7 (NTFS)
w (write and exit)
答案2
尝试
mount -r -t ntfs /dev/sda2 /mnt
这应该以只读 ( -r) 模式挂载分区。
这假设没有对分区进行任何操作。
您可能需要执行 fsck，即dosfsck首先使用 -n 选项。
