Need help with a dish dvr 722 and anexternal drive

after storing 80 movies on my external drive, the device now says it must be reformatted. i have d/l a linux drive reader for my pc, but it can not find a single file. I have read that these movies are encrypted. its there a reader that can help me? i dont need to save all the files, just the one that can no longer be replaced.

HOW would you connect to the movies?

well i was hoping that i could copy from the drive to another drive. then reformat the dvr drive and and copy them back.

the linux reader i have can read the partitions but no files. i am using lunix reader to read the drive.
