I looked up the problem, I have similar to another person. Except I unintentionally disconnect my external hard drive while it was in use and the was a recording going on while this was happening and worked for a little while and the recording resumed. About 1/2 hour to hour later it started doing this. Is it a "toxic" tv channel or corrupted internal or external hard drive. I did get that screen telling me to reconnect the external hard drive when I had it disconnect otherwise it would boot up OR press the clear button the remote to continue.
Is all my data lost or is there any way to fix this, can I recover this data if it is corrupted?
