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 复制代码
设备文件类型查询， 使用 root 用户执行 blkid 命令
root@w:~# blkid /dev/loop0: TYPE="squashfs" /dev/loop1: TYPE="squashfs" /dev/loop2: TYPE="squashfs" /dev/loop3: TYPE="squashfs" /dev/loop4: TYPE="squashfs" /dev/loop5: TYPE="squashfs" /dev/loop6: TYPE="squashfs" /dev/loop7: TYPE="squashfs" /dev/sda1: UUID="9f6a2add-e287-4bf7-8e71-76cde406b11c" TYPE="ext4" PARTUUID="ca890f89-01" /dev/sdb1: UUID="5B15-2493" TYPE="vfat" PARTLABEL="EFI System Partition" PARTUUID="d176220a-1c9f-4fba-9855-e24269a3dbe9" /dev/sdb2: UUID="b9bceef6-f44c-4882-9216-1d6b8ecf1e43" TYPE="ext4" PARTUUID="9798f821-a39c-4622-b367-c5f842620db1" /dev/loop8: TYPE="squashfs" /dev/loop9: TYPE="squashfs" /dev/loop10: TYPE="squashfs" /dev/loop11: TYPE="squashfs" /dev/loop12: TYPE="squashfs" /dev/loop13: TYPE="squashfs" /dev/loop14: TYPE="squashfs" /dev/loop15: TYPE="squashfs" /dev/loop16: TYPE="squashfs" /dev/loop17: TYPE="squashfs" /dev/loop18: TYPE="squashfs" /dev/loop19: TYPE="squashfs" /dev/loop20: TYPE="squashfs"
