Some further notes: Since I no longer have a Plextor drive (which came with special software for bit-accurate DAE), I'm using "Exact Audio Copy" to extract the WAV files from the audio CDs. The program generally works well, except that it seems to be oriented entirely toward "ripping" commercially-available CDs. It continually compares the checksums of my tracks with entries in a remote database, and its responses depend on whether there's a match between my tracks and anything in that database; of course my tracks are never there, except for an occasional "false positive". I wish that I could turn that feature off, but I don't see any way to do so. It also results in the checksums of my tracks being added to that database, which only increases other peoples' rates of "false positives".
Apparently the only tech support for EAC was on a Yahoo user forum, but it is closed now because Yahoo has left that business, and I don't see any replacement for it.
--I used to be concerned about the "timing problems" that the program reports, but am less so now. After one extraction had slowed down noticeably and five or six such "problems" were reported in one track, I cleaned the disc, renamed the extract file, and ran that track again. This time the extraction happened at full speed, and only one "timing problem" was reported. I then did a binary file comparison with the previous extraction, and it was bit-identical throughout.
