将 /dev/sda1 对应的 /media/w/9f6a2add-e287-4bf7-8e71-76cde406b11c 目录内容挂载到 /mnt/sda1 目录中，使用 sudo mount /dev/sda1 /mnt/sda1 命令

注意
这样挂载完以后的目录，电脑重启后挂载的内容就没有了，需要重新操作，解决方式如下
使用 root 用户在 /etc/fstab 文件中添加一行内容 /dev/sda1 /mnt/sda1 ext4 errors=remount-ro 0 1 这样电脑重启后挂载的目录依然还在。
root@w:~# tail /etc/fstab # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> # / was on /dev/sdb2 during installation UUID=b9bceef6-f44c-4882-9216-1d6b8ecf1e43 / ext4 errors=remount-ro 0 1 # /boot/efi was on /dev/sdb1 during installation UUID=5B15-2493 /boot/efi vfat umask=0077 0 1 /swapfile none swap sw 0 0 /dev/sda1 /mnt/sda1 ext4 errors=remount-ro 0 1
设备文件类型查询， 使用 root 用户执行 blkid 命令
