ubuntu mount hfsplus partiton

sudo apt-get install hfsprogs

Next, mount or remount the HFS+ drive; commands need to be as follows:

sudo mount -t hfsplus -o force,rw /dev/sdx# /media/mntpoint

or

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

Finally, if the drive was improperly unmounted or has otherwise become partially corrupted runfsck.hfsplus (provided here by Jayson) as such:

sudo fsck.hfsplus /dev/sdx#
