Firstly, this assumes you have already added the partition to /etc/fstab to be automatically mounted

chown -R user:user /path/to/mountpoint
Otherwise, you can either
a) Create a group that can write to the folder, and add any user that wants to access the drive to the group.
b) Just chmod to 777 - that will allow anyone to access it.
chown -R root:group_name /path/to/mountpoint
chmod -R 770 /path/to/mountpoint
