@Tester_1: In the thread for the BDR-212 / S12 (provided in the Summary of the article), we provide results for most CD-R MIDs at all available speeds. The maximum speed is 40x. And you are correct, I had a problem with my DW1620 until recently, and it has been replaced. The newer one scans much better. The old one is doing time in my closet for bad drives.
@ Jesse_Viviano: You are correct that there is a drive utility with a couple of software utilities that are supposed to improve error correction when playing audio CDs and DVD/BD movies. However, these utilities are only available for advanced drives (e.g. BDR-S12J), which most folks will not have access to. The error correction testing we did was done using a BDR-212D, which does not utilize the utilities. We’ll add it to our wish list of testing to do.
@ Oinker: The newest batches of CMCMAG-BA5 from MediaRange and Verbatim are much better than earlier batches and those from others (e.g. HiDisc, Maxtek). Your recent testing has shown similar good results with the newest batches.
