Diagnosing Why a Disc Won't Finalise

[Ninguno]

I burnt data onto a DVD-R using Nero Express Essentials. When inserted into the drive it shows as empty. However another application shows me the files I burnt on there but I can't access them. ImgBurn provides these details about the disk:

If I try to close the disk using Tools > Drive > Close > Disc, I get "I/O error! Invalid field in parameter list".

 

Is there a way I can close this disc and access the files on it?

 

I might add that this is unusual, I have successfully burnt many discs using Nero, this is the first time I've had this problem. Subsequent burns were also successful.

Try Tools -> Drive -> Close Track / Session / Disc (in that order). If it doesn't work then you should use IsoBuster to extract your files.

I have tried that already.

I will download IsoBuster as you suggest.

OK. IsoBuster allowed me to transfer the files to my hard drive and I have now burnt them to another disc, and verified the burn which was fine. So thanks for that mmalves.

 

Out of interest, were my attempts at trying to close the failed disk doomed to failure? My theory was that the disc had somehow not been closed, so my initial focus was on trying to find software that would close it and that would then allow me to read the files.
