Called Apple and THEY couldn’t help either (after asking me if i tried everything -which I had) So I bit the bullet and bought DiskWarrior for $128 and crossed my fingers. MNT_EXPIRE (since Linux 2.6.8) Mark the mount point as expired. You can issue command umount -l with that partition and the unmount will be done after the disk operations gets finished. I've tried to force an unmount, but it doesn't seem to work: $ umount -f /mnt/data $ umount2: Device or resource busy $ umount: /mnt/data: device is busy If I type "mount", it appears that the directory is no longer mounted, but it hangs if I do "ls /mnt/data", and if I try to remove the mountpoint, I get:

Windows assigns each volume a drive letter such as C: or D: and the file system for each volume is a tree of directories sitting below that drive letter. MNT_FORCE (since Linux 2.1.116) Force unmount even if busy. This is a special option in umount, in case you want to unmount a partition after disk operations are done.

Even tried terminal, and force mount on terminal and it’d give me the whole try Read Only mount –also didn’t work. The configuration file /etc/fstab contains the necessary information to automate the process of mounting partitions. Related Read: NFS Mount Options in Linux I modified your comment just in case a curious reader tries running your command. The file systems in Linux, macOS, and other Unix-like operating systems don’t use separate volume identifiers for storage devices in the way that, say, Windows does. In this tutorial, we are going to see how you can mount and unmount drives on your Linux system. In this tutorial, we learned different options available when you are unable to umount in Linux and Unix style system. In this tutorial, we will learn how to mount (attach) a drive in Linux with the EXT Linux file system, FAT or NTFS using mount … I don’t know why you would have a mount point in the /root directory. This prevents you from writing to the drive, and thus prevents you from changing what might be actively used by another OS, which in turn might corrupt the entire other OS upon reboot. Which mounts the drive as read only . On Linux, mounting drives is done via mountpoints on the virtual filesystem, allowing system users to navigate the filesystem as well as create and delete files on them.

You would prefer to use the -r option (sudo mount -r /dev/sda2) to force read-only mode. If you have any questions or feedback, feel free to leave a comment. All mentioned force umount option explained should work on all Linux distribution like Ubuntu, Mint, etc.
