abalone: i know what u mean by diffrent scan results from diffrent drive [after all i went nuts from trying to make sense of these scans.] but the point of these scans were [besides the confusion over c2 error reporting by the benq] was to find out which of these 3 drives were better @ burning cds, so i could use that drive exclusively for that purpose. since i put another 50 bucks into the 1693s, if cannot do anything other than just better scanning id rather return it and put that amount towards a 1640 instead [plus i also have that 52327s, but im not sure whats wrong with it, as the burns dont seems that gr8 anymore!]
i also know from experience that most dvd burners are not that good at burning cds, ie. nec nd-3500. as for the benq, well after the hell i went through with the 3500 [screwed up atleast 30+ discs and a whole lot of data ill never get back b4 i figuered it went crap,] lets just say im impressed.
FactFinder: thanx for the comments. but like i said, im trying to find out which of the 3 drives are better @ burning cds [i already figuered that the 1620 is far better @ burning dvd's than he 1693s.] and the reason for my posting these scans were that [experts] with experiences with these particular models for years and a good knowledge in scans [well im just beginning with the scans, but atleast ive got the hang of dvd pie/pif scans but these cd scans are totally confusing and not least because the benq is reporting c2 errors where i thought after reading countless articles/reviews that it couldnt,] could make some suggestions/comment that would help me out with cd burn quality issues.
and yeah btw factfinder, i have posted cd scans set @ MAX b4, its here http://club.cdfreaks.com/showpost.php?p=1058135&postcount=15
and thanx for all the help u guys.
