raspberry pi auto mount usb drive

my drive is hfsplus usb 2TB

get the usb UUID from blkid

pretty print drive locations lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL

followed this, with special attention to the order. Drive must be unmounted before running fsck.

sudo su
umount /dev/sda2
apt-get install hfsplus hfsprogs hfsutils
fsck.hfsplus /dev/sda2
mount /dev/sda2 /media/usbdrive
echo "UUID=802a74ed-8f65-3294-83d5-c4bdcf9e08d7 /media/usbDrive hfsplus force,rw 0 0" >> /etc/fstab

Since the drive was originally setup on osx, I needed to update the mount point chmod ug+wx /media/usbdrive. This allows my user to write to the drive. I also added my user to the disk group, usermod -a -G disk tod.

not sure this is needed

for hfsplus drives to work on linux as rw, need to mount drive on osx and run sudo diskutil disableJournal <drive name>.

Moving the drive back to the raspberry, chown -R 1000:pi /mnt/usb/. This is uid of the pi user.

And it works! drive is now read/writeable.
