I’ve been able to burn a full disc successfully when using the standard Nero data burning program. 1 out of 3 had errors using that method.
For Nero BackItUp3 there are two ways to backup your files:
One way is to use the Nero archive format. I’ve burnt 2 with 0 errors this way.
The other way is to keep the files in their native format. (which is the way I want to have them) This is when the majority of errors have shown up. I’ve burnt 4 and 3 had errors.
With this information, do you still think it’s a media problem?
