How to mount a HFS+ partition in ubuntu as read and writable

Make sure hfsprogs (https://tracker.debian.org/pkg/hfsprogs) is installed:

sudo apt-get install hfsprogs

If the partition is already mounted. Check in Disks utility. Simply remount it:

sudo mount -t hfsplus -o remount,force,rw /media/nameofmountedpartition

Otherwise you can mount it to your own mount point:

sudo mount -t hfsplus -o remount,force,rw /dev/sdx# /mount/point
