I am looking for a hard disk device to store raw images ( Canon .cd2 ). As the Compact flash card just cannot hold enough for a trip, and multiple cards are expensive. Is anyone aware of a device, 20 or 40 MB that works well, supports raw, accepts compact flash and usb to the pc. I don't care for a device that holds video, audio, etc. Just a good, reliable storage for raw photos.
If you have experience with something like this I would love to hear from you.
