Hyperdrive makes these. http://www.hypershop.com/HyperDrive-s/119.htm A shell costs $99. Install the drive of your choice, up to 1TB. Internal rechargeable battery with good capacity. One version will serve as an external drive (of sorts) for the iPad, so you can dump your SD cards to the Hyperdrive, then move the images to the iPad for minor editing and display (e.g., to share with your fellow travelers or with the villagers you are living with.) If you have enough cards, don't reuse them. The Hyperdrive provides a primary back-up and the iPad provides a secondary backup. stan -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
