I just saw something weird and I was lloking for input. I had been testing a number of external cases so I was using CDSpeed's create a disc with simulate dwriting. Most drives performed as expected on this media and I was running most tests at 16X to stress the through put. I ran some TYG02 on my NEC 4570 at 8X and got essentially a flat line at 8X.
They I ran some MCC 03RG20 at 8X and saw a drop half way though the burn to 4X where it stayed till the end of the burn. There was no other CPU or buffer activity to cause this and prior to this the MCC had been tested at 16X and made it well past 13X.
Does the burn strategy for 8X really call for a drop to 4X on this media?
