Look at the numeric scale on the left. That is what tells you how hight the errors are. Notice how yours in the second one goes up over 400 in the first graph? Notice how rbrtpl’s only goes up to 8? yours it crap, his is very good. Same for pif, his is much lower. While it doesn’t nesasarilly make a burn unreadable (you can have kind of a lot of errors across the whole disk but if they do not spike up too high in one spot, the disk still may be readable), look at the number of errors at the bottom. pi 2,197,997 pif 5842 on your second one. On rbrtpl’s, pi 14,884, pif 55.
The book standard allows for 280 max pi and 32 max pif. Due to variations in equipment, mass production, the fact that these drives are not professional scanning equipment and the push to competitivly get equipment out cheap with burners, dvd players, disks, whatever, a disk that is a little under those limits may have some playability problems or may play just fine. It is perfectly reasonable to expect burns substantially under those limits, but yours is obviouslly over them. rbrtpl’s scan is very good by the way. If it had gone up to 40 pi, it would still be just fine, but why not shoot for the best (the nec’s are good drives so you can shoot for the best). Personally, I require under 20 pi, under 3 pif (on k probe which has a lower pif scale) on my own burns to consider them good and continue to use that media, but you can easilly go over that and still be fine.
One more point. Stop thinking in terms of brands when it comes to disks. Download dvd identifier and start thinking in terms of media codes. The disks rbrtpl is using are are mcc004. It just so happens that verbatim 16x+r are just about guarenteed to be mcc004, but with most brands, thats not the way it works. They may be several media codes from the same brand, format and speed. Even though mcc is manufatured by mitsubishi (the parent company of verbatium), there are other brands where you can find mcc media too as they sell to other companies.
mcc004 would be an exelent choice of media to try, but I don’t think anyone has any on sale this week (might want to try micro center if there is one near you or see what is on sale online, check the bargain basment). Being on sale makes a drastic diffrence in price at the retail stores (many stores sell 50 packs of verbatium for 40$ but sale price is under 15$). check this thread
Circuit city has nexxtech on sale for about 7$ per 25 and if you know how to identify them (see the thread), you can get mcc02rg20 (same as verbatium 8x-r) though some are reporting getting mcc03rg20 (same as verbatium 16x-r) even though the package says 8x.
Does anyone know how the nec 3550 does with -r media? My nec 3500 does just fine with the ones circuit city has. there is a scan posted in that thread of the 8x stuff on a disk that was burned 7 months ago and scanded just the other day. I have no idea about the spike at the begining because they do not burn like that for me but it was the only disk handy to scan (maybe it is because the disk is scratched up)but still the spike only goes up to 40 pi (not 400).
Fyi, rbrtpl, sorry to talk about your post instead of letting you talk about your own scan, hope I didn’t offend.
