How to forcefully unmount a disk in Linux?

In the Linux system, you can use the umount command to forcefully unmount a disk. To force unmount a disk, you can follow these steps:

1. display disk usage in a human-readable format

df -h

1. Locate the mount point corresponding to the disk that needs to be forcibly unmounted.
2. Use the “umount” command to unmount the disk, for example:

umount -l /mnt/disk

In the command above, the option -l indicates a forced dismount of the disk.

It is important to note that forcibly uninstalling a disk may result in data loss or damage, so it is recommended to back up important data before performing this operation.
