我尝试了一些东西，但它不起作用。对于我来说，该sudo fdisk -l命令给出了以下输出：

我想挂载这个/dev/sda，它是朗科外部SSD。这是lsblk输出：

给sudo parted -l我的输出如下：

安装 ntfs-3g 后，我尝试了以下命令sudo mount -t ntfs-3g /dev/sda /media/ntfs/：
NTFS signature is missing.
Failed to mount '/dev/sda': Invalid argument
The device '/dev/sda' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
我也尝试过这个udisksctl mount --block-device /dev/sda ：
Object /org/freedesktop/UDisks2/block_devices/sda is not a mountable filesystem.
试过了sudo mount -t ntfs-3g /dev/sda2 /media/ntfs
，它说：
ntfs-3g: Failed to access volume '/dev/sda2': No such file or directory
ntfs-3g 2021.8.22 integrated FUSE 28 - Third Generation NTFS Driver

我现在能做什么？
现在问题已经解决了。我安装了gparted，然后我更改了分区的标志，它首先在msftdata上，我重新选择msftdta并关闭它。然后我看到我的 SSD 被识别，然后我尝试
sudo mount -t ntfs-3g /dev/sda2 /media/ntfs并安装了它。谢谢大家的支持。
