I am shooting nef ( or raw) images these days with my D70. They are only viewable with the Nikon view software installed on the hard drive of my home desktop computer. I am looking for suggestions on how to back up these NEF files for safe storage in the event of hard drive failure, which as we know WILL eventually happen. My thought was to use an external drive and just store them on that, but since the Nikon view software is only installed on the "C" drive I can't view the ones on the storage drive. Should I just copy them to the extra hard drive, and forget about viewing them until I want to bring them back to whatever drive has the Nikon view software installed? Another option is to just keep them stored on the compact flash memory card I guess, but not sure if that is a good solution.
