I’ve noticed there are speed drops during a burn with WOPC off when burning on a 1640. Is that normal? I thought WOPC would mean it would just burn with a straight line graph in CD Speed and it’s at your own risk as to whether the media can handle it or not.
The 1620 seems to commonly drop speed at the same point at 12x looking at a few graphs from 1620’s with WOPC disabled. The 1640 seems to vary from graph to graph. Some burn through with a speed drop 2/3rds through while others keep dropping at several points through the burn but still with the characteristic speed drop 2/3rds through the burn.
