Yes, your drive says it can't read several parts of the disk. Most likely causes are dirty or scratches, followed by a bad pressing at the manufacturing plant.

If cleaning doesn't help, and it's a new disk, consider getting it replaced.

Thank you. Ive had them awhile and there is no scratches on them and they look clean. I will try giving them a clean incase its something i can't see on them. Think its too late now to get them changed.

Thanks for your help

I have given it a wash and now its working fine. Thanks for your help
