I'm hoping someone can tell me what I seem to be doing wrong with my K1. I've had it for almost a year now and decided a month ago to clean up all the books in content manager and deleted pages upon pages of books. I went into Buffalo two weeks ago and turned on whispernet and all of the books have shown back up. When I try now to delete these books I'm not even given the option while in Content Manager. I'm offered only move to kindle memory, even move to SD card isn't highlighted as an option. The books show that they are Amazon vs. Kindle so I'm not sure if that makes a difference. I'm afraid to reformat because alot of the books I have on the kindle were free downloads that are no longer available. Any suggestions would be greatly appreciated. I posted this over on Amazon too but I think kindleboard users tend to be more helpful with answers instead of critical.
