Just one more comment (Attn: I don't know anything about the techniques of recording on a CD/DVD) As Joerg suggested in private mail, I tried using cdrecord after I had stopped hald. So on my system even without hald running cdrecord refused to write even the first sector. Switching to -raw96r mode (on a CD) did succeed but readcd -c2scan failed. Joerg said that my drive (LG GH22NS30 SATA) does not support c2 scanning. But then I wonder why it didn't get errors for all sectors (just many). I tried PLATINUM and VERBATIM media. This seems to be connected to this burner (and its predecessor LG GH20NS15) I have two PC (both AMD 64 running a recent Linux system with an 2.6.26 or 2.6.28 kernel) Both show this problem (with cdrecord only). I don't think it has to do with this recent Linux kernels since on two 32bit machines, running 2.6.26/8, as well, I have no problems though with an older (LG) burner. I managed to burn the CD with cdrskin, I mounted that CD and compared to the source directory. And the data was OK. I tried to "verify" that same CD with readcd (c2scan) and it failed with many sectors. cdrecord even failed to burn a DVD on those machines, while growisofs succeeded. NOTE, this is just the short history, no rating ! Thomas suggested to use CDCK which validated both the CD and the DVD. But unfortunately that checks timings only and therefore is only an indirect measure of quality. I wished there a were a tool which could show "near failures" on a CD and on a DVD, since I use my burner for backup purposes only. And I want to be able to access my data even several years in the future (e.g. digital photographs) Thanks for all your help and I explicitly include Joerg here, as well. I have been using cdrtools for many years now and it had worked and is working flawlessly except on this new hardware.
