My wife brought to my attention that our external dish network provided hard drive is no longer showing up on our recorded items....We have a lot of stuff on there....When I unplug the power and wait a bit then plug it back in I am asked if I want to reformat this device. Doing this will erase all the movies and programs that we have saved.....Is there any work around this? Some have mentioned that this happened after a software update on the 5th of Dec.
