Firstly, thank you Whappo and StormJumper for your quick responses, really appreciate them.
[QUOTE=Whappo;2223183]Just a thought: If a have a linux cd why not boot into linux, insert the DVD and see if it’s recognized. I’ve never tried xfburn so I can’t say if it finalized the disk or not. If you only have one CD drive you can download Puppy, burn it to CD, boot from it, and then you can remove the boot CD. It runs in ram.[/QUOTE]
It was actually a version of Puppy Linux that I used to burn the DVDs (NOP 4.x, can’t remember the exact version number, the USB pen drive I had it on became borked after a dodgy format). I tried doing just as you describe with a newer version of NOP (only know it was newer as it had a different desktop picture), and the disc wasn’t recognised.
[QUOTE=StormJumper;2223190]Well ISO Buster should work, have you checked to see if the discs are closed ? you can use Nero CD Speed to check that and if is not you can use ImgBurn to close it also you may even try ImgBurn to recover the data since it has no protection ;)[/QUOTE]
Discs are closed? Sorry, you’ve lost me there. I’m also fearful of making any changes to the disc before I’ve backed it up somewhere. Could it be to do with the verification process (might have skipped it)?
Backup first then extract data, that’s the plan right now. If the data is on the disc without a TOC/recognised format, can the data still be extracted (use some software that allows 1 for 1 copies of discs perhaps?).
