My TEAC CD-W540E, which has previously worked wonderfully is now making coasters and won't burn >24X using Nero 5.5.x or EZCD 5. I have run Nero CD Speed several times, and the drive starts at 20X (as it's Z-CLV), steps up to 24X OK, but then slows and then steps back to 24X, not 32X as it should. It remains at 24X for the rest of the disc. It will make a coaster when burning a data disc with either Nero or EZCD. However, I successfully burned a data disc using Feurio using Z-CLV, and I believe the burn stepped through both 32X and to 40X. The burn should look like this , but the last 2 steps aren't there.
I have never had any problem running all 3 burning programs with Win XP (and I do the same on a Win2k machine at work). I have done 2 things recently that may have brought on this problem. I updated the firmware on the drive from 1.0H to 1.0K; however, I have since changed it back to 1.0H and the problem persists. Perhaps a more likely culprit is that I updated my EZCD from 5.3.x.x to 126.96.36.199. I have generally disabled DirectCD, as I have heard that it can cause problems, but I don't think there was any choice in the upgrade to selectively install only some options, so it is now installed; if there was, I missed it.
Any suggestions, other than completely uninstalling and re-installing all burning S/W? Can I just uninstall DirectCD? I seriously doubt the drive or F/W is the problem, since Feurio seems to operate correctly. I can certainly provide more system info if needed.
