# From the above output, the system has found the new hard disk partition. Device Name:/dev/sda6

# Now, you are ready to edit fstab to enable ubuntu to mount this ext3 extended partition. Back up fstab first, just in case.

Sudo cp/etc/fstab. bak

# Because the ubuntu system treats all hardware resources as files, we need to create a folder to serve as the access entry after the hard disk partition is mounted in the future.

Sudo mkdir/mnt/ext

# OK, and then start editing the fstab file.

Sudo gedit/etc/fstab
