Outcome: STABLE provides Read-Only Access on Linux
First take your portable drive, format it on your macbook using the HFS+ filesystem, complete, unmount and disconnect.
Next go to your Linux machine, in my case Ubuntu 10.4, and install hfsplus
sudo aptitude install hfsplus
Connect your portable drive and voila, it's automatically mounted on your linux desktop.
