Heh, im a complete newbie to error analyzing on discs, and im trying to help the out by providing information on how effective plastic cleaners (such as novus and plexus) work on dvds and cds when backing up. However i dont know how to use kprobe, all i was able to find were posts explaining what an error is, i dont know how to interpret this data to the forums, can i have some help as to explaining how good scans from kprobe are? Any guides, tutorials, explanations, etc etc.

This should help you on your way…
