I don't know if my drive is among the pickier ones, but it surely causes lots of troubles than it's worth.
I was happy burning @48X with the Ritek-made TDK 40X-certified CD-R (the so-called JS dye). After I run out of disc I went out to buy another 100-disc spindle of the same brand, and now whenever I burn @48X lots of errors appeared in ScanDisc. I compared the new discs with the old ones and they are identifical to my eyes except that the codes in the inner rim of the new ones are more transparent. Now what should I do with my new discs? Should I try my luck to buy another spindle?
