I'm not sure if this is a hardware, software or media problem, so I put it in the newbie section. I have a laptop with LG GWA 4040N, a few boxes of mitsumi DVD+RW, and roxio 6. I haven't used any of the discs for a few years and wanted to do some backups, but when I format them with drag-to-disk, all of the unformatted discs report a write error. Discs that I had formatted earlier seem to be fine, and I also burnt a few DVD-Rs recently without problem. So how can I figure out if: a) all the discs are faulty (no access to another drive) b) the drive if failing, or c) the problem is with Roxio. I am not aware of another UDF formatting tool, but have nero 6, alcohol, imgburn installed, as well as dual boot with ubuntu. Any suggestions?
