New problem, probably related to all the above.
My HDD (1TB) was about 70% full. While deleting a few folders I noticed the total available space was not increasing. After a shut down and reboot, the function returned to normal and I deleted some more. However, a check on the hard disk resulted in fail, error 8. There are suggestions on other sites that the HDD should be reformatted or replaced. If I have to do either, how can I get all my recordings off to an external HHD? I have copied a few files to USB in order to make DVDs and it takes ages,
