Message "failure data transfer system"

Hello everyone.
Does anyone have an idea for my problem?
Thanks to those who will be willing to help me.
Best regards.

Hello gigi38,
"I record TV shows without any problem": OK. How do you know that?
How is it connected?
To the TV but with what cable?
Is your TV connected to a box? A rooftop antenna?
You need to check the sources, from the TV (TNT?, Box?, Antenna?...)

"but I no longer have access to the library": What do you mean by library?
Are you sure about the source to read the media from the player (DVD, DVD-R...) to select on your TV?

"this message appears "data transfer system failure"": On the TV? Yes, of course!
Best regards!

Hello txiki and thank you for your response. Yes, the recordings are being saved very well, because everything was working properly 5 minutes before. There is this message that appears "system data transfer failure." To remedy this problem, I am told to cut the power and restart, but nothing works. For the connection, it’s a SCART cable. The library is the list of all my recordings. I can see this list appear for a fraction of a second before the fateful message appears. I remember that once I had the same problem and I fixed it by making a one-minute recording, and everything went back to normal, but right now, there is nothing to be done; no solution to my problem. As for the source, yes, it's the hard drive. I would have liked to copy some recordings from this library to my computer, but when I connect the hard drive to my computer, it’s impossible. In any case, thank you for your help. Best regards.
