I continue to have problems keeping up with this HR54. It is always on the edge of running out of space, last night showing only 6% free space. I proactively deleted many many recorded shows and it didn't seem to be gaining much ground until I deleted one 30 minute show which then all of a sudden showed me at 20% free space. That made me think about defragging like I do on my Laptop. Is there a way to defrag the HR54 without having to "Reset Everything" and then rebuild my lists and losing all of my existing recordings? I'm sorry if this question has been asked before, I couldn't find an answer. Thank You for your help!!!
