Hi, I have just purchased Lite-on 1693 (and a CDRInfo registration ) and started some testing. Not a bad drive I think, though definitely not the best. But I was taken aback by this issue: burning on Verbatim 52x CDs gives these results in Kprobe:



Those C2 spikes appear on every CD i burn, +/- the same possition and value. I haven't tried another brand yet, because I don't have any at my disposal at the moment. I tried burning at 16x, 24x, 36x and 40x - always approximately the same result. What could cause these spikes? Burner? CDs? Sorry if this is some triviality, I am a beginner in this area and this is confusing me quite a lot. And another interesting picture. The same cd in CD Speed:



No C2 errors at all. Any help or advice is welcome

Ignore the spikes. Its a bug of the drive's chipset. This happens all the time. Nothing to worry about.

You can remove them if you like by right click on the graph and select something like "remove highet spikes/values".
