You'll have to reformat the drive. You cannot delete a single partition (or P2 card data) in the camera and I don't know of a way to do it in the MAC OS. I think there are probably third party partition management programs that might let you do it but I'm not sure if that would interfere with the cameras ability to offload future cards. I usually reformat the drive after I'm sure the offloaded data is secure and backed up elsewhere in my workflow. The offload process is really just a convenience in the field for dumping data until you get back to the studio and ingest your footage. I rarely keep more than 4 or 5 cards worth of data on that drive.
