Albert, I currently only have one drive that is capable of disc quality test which is iHAS 124-19 B, and this is able to test at 12x & 16x speed only.
Matth, that's interesting, but is the transfer rate test available in Nero disc speed please? I'm sure the option is starring at me, but can't see it. I'm not too familiar with disc speed as only really ever used for the disc quality scan.
Just going through the options now and looks like it's the green line of the benchmark that should be concerned with correct? How would you interpret bad quality, or in other words how much of a drop would be considered a bad burn?
I have a strange outcome comparing the benchmark to disc quality scan across different drives. Using a known bad burn with a disc quality reading of ZERO using my iHAS 124-19 B, where the benchmark also fails to complete, using the same disc in my LG BH10LS30, it's not only able to complete the benchmark, but also with no drop in speed. If I've understood correctly, this would suggest 'good' burn.
I guess then some drives are more capable than others, where as some will happily read supposed bad burns, where as others will cry and spit it's dummy out, correct? If that is the case, this then begs the question, can any of these scans really be relied on?
