Cd contents

I have copied a cd’s contents to my HDD. But when I try to run it, I get a message saying Original media not found. Anybody got any ideas please.

The simple answer is what you copied are the .cda pointer files.
They are only a small file & not the audio file that contains the musis.
Try EAC ,
Or dBpoweramp CD Ripper (free after trial).
Or CDex .
What you will get as default are .wav files usually.

EAC takes a bit more setting up .
