I have aset of backup discs and was trying to copy them with nero,but it keeps coming up problem with reading disc have tried a few of them and it is always the same I don't use nero often and would like to know what I am doing wrong am using the cd copy on nero do I have to use a different programme

it could be the discs are knackered m8 or the cd reader is knackered. try putting them in a writer to read as they might not have been 'closed' when burned originally
