Hi, I'm trying to back up some software to disk but when I try to burn the folder over to CD I get an error message. I'm using Sonic RecordNow, could that be a reason? The error message says either to try a different manufacture or clean the disk. But the disk was straight out the case new so I doubt that is the case. My brand is Maxell CD-R 80 XL-S 700mb. I'm trying to burn over a file about 600mb. (For the record my pc has got a cd rewriter). Cheers,
