I’ve had my LTR-52327S (Rev 2) for several years now. However, I recently noticed that I still had the original QS54 firmware on it. I just upgraded to QS5A, and WOW what a difference! Now it burns at P-CAV instead of CLV… so it takes 3.15 minutes to burn a full CD-R instead of 6.25 minutes. Although the C1 errors went up a tad… but not by much. You guys might want to upgrade for those whom still use this old drive (I just use it to burn CD-R)… but then again I just use TY CD-R’s.
Here are some scans:
