Help making additional Storage partition

[Ghost Hacks]

I currently have a 1TB SSHD in my laptop with the following partitions on Linux Mint 18 MATE.
sda>
sda1>swap 24GB
sda5>lvm - / 150GB
sda6>lvm - /home 325GB
sda>Free Space 500GB

I would like to use the 500GB to make a storage/backup partition but would like it to mount as a external drive does, showing on the desktop etc. Is this possible?

you should be able to just format it to NTFS / fat32 / ext4
using Gparted to do that & as sda7 on the system.

you may have to modify some settings / files if you want it to auto-mount,
- if you don't want to be always manually mounting that partition.

It's possible and pretty easy and has been covered here a zillion times, as a forum search for [data partition] would show, or better yet:

Basically: make a partition, make or choose a mount point, and make an entry for it in /etc/fstab.
