i've spent all morning reading through this site trying to figure out how to test the quality of my burned media, and im a little confused about the results. i've been burning mostly with good quality media at compatible speeds (8x dvd 32x cd) with predictable results. however, some of my discs give errors or stop working after awhile, which i associated to cheap media, but with the current relativity of the very term itself i have come to the conclusion that scanning is the only real way to test whether media is good or bad.
for example CMC media is generally bad, but some give very good results.
anyway, here are some of my results:
HP 640C QS12 (a HP640i drive): every dvd gives the "no additional sense information" error, with a cd this error came up about 15 seconds into the test; this is my primary burner, but i take it that it does not have scanning capability.
scanned from my 3550A this time- good media, good burn, good quality. the test reflects this; disc plays fine, no problems.
CMC - definitely questionable media, but i dont get what happened with this test. Scandisc tells me the file is ok and all the sectors are good, while running the quality test on a NEC2510A instead gives me no PIEs, 7 PIFs and a quality score of 73; i guess i can infer that the 2510 doesnt have proper scanning capability either, but whats the deal with the 3550 test?
how can i test the true quality of this media?
prodisc (fujifilm), another questionable media. a quality score of 45 isnt very good, but the PIEs are within the threshold for a good burn (<280), meaning this is decent, right? (considering this is cheap media...)
i havent had any playback problems with this or any fuji burns, both software and standalone, so what can i infer from this test?
