Using new formatted paritions on linux

When setup linux on my system, I created several new partitions other than home
Once I finished installation, I found out I could only view these partitions, but not copy to them or remove from them

The reason is because these partitions were formatted by a filesystem owned exclusively by root

To change that, change the owner of the partition

mount /dev/sda4 /mnt/
chown -R khaled:khaled /mnt/
umount /dev/sda4
