Verbatim 700MB 80 minute 52x CD-R Made in Taiwan (bought April 2022 from Amazon for about $18 for a 100-pack of CD-R’s)
Audio CD of 80:53:09
Burned on Sony Optiarc 7240s (v1.04 firmware) @ 16x (with ImgBurn v22.214.171.124 on Mint v20.3-Xfce through PlayOnLinux using Wine v6.0.1 32bit)
Burned on Apr 17th 2022
Scanned on Apr 30th 2022 with Liteon 24102b @ 8x with KProbe v2.5.2 (running on Linux Mint v20.3-Xfce through Wine 32bit v4.0.4)
p.s. that’s the best disc scan overall of the about six Verbatim CD-R’s I burned recently from that same 100-pack bought in April 2022 from Amazon. the worst, in terms of total C1’s 54.6k. but overall I am not concerned as they play fine on my original CD player which has a April 1991 mfg date on it and at about $0.18 a disc it’s difficult to complain.
side note: I just scanned a generic ‘Precision’ CD-R (‘Prodisc Technology Inc’ media code), which was probably burned on Liteon 24102b at 16x I think, and that scanned quite a bit better than my Verbatim CMC Magnetics and those are old discs to as I am pretty sure those are no newer than 2004 when I bought them and that particular disc was burned May 18th 2019 and I got C1 = 19 max, 0.62 average, 2788 total and no C2 errors. hell, even my Mitsui CD-R’s which I paid I think about $50 for a 100-pack (which are probably 20 years old now or so and I still have a good portion of these left), don’t scan that good as I burned one not long ago on Liteon 24102b @ 8x, which at least that one particular disc burned recently was overall worse than these cheaper CMC Magnetics Verbatim CD-R’s I bought recently which basically comes out to $0.18 a disc vs the Mitsui about $0.50 a disc.
From a post in Dec 2006, DrageMester said… “KProbe can still be used for performing C1/C2 Disc Quality Scans on LiteOn CD-RW drives and some DVD drives. The results on LiteOn DVD drives are not reliable however, because at least the latest generations don’t report C1 errors correctly”
even with my Liteon iHAS324B (DVD burner) you can tell that does not do proper C1 correctly as it does not give the steady stream of C1 info like I get when doing it on my Liteon 24102b CD burner (Dec 2001 mfg date).
