i am using Optical Quantum discs (support 4x, 6x, and 8x write) that show up as RICOHJPN-D01-67 in my drive, which is the iHAS524 B (AL2A). my first two tries with an XGD3 iso and the Burner Max fw failed. one burned successfully (at 4x OPC on) and then failed the Verify at 2112448 sectors. the second (also 4x OPC on) failed to Write at 2116736 sectors. for reference, the first layer should go to 2133519, so they failed near the outer edge of the first layer.

for some reason i decided if i could burn the disc at 2.4x, it might be less likely to error. i did some research and found that the dvd drive firmware stores a list of media IDs and what speeds they are compatible with. i found a program and modified the firmware to think that RICOHJPN-D01-67 discs support 2.4x. my first burn was successful and also passed the verify. just to be sure, i put the firmware back to normal and verified the disc again at regular speed and it passed again.

i am now trying my second disc at forced 2.4x with OPC on. i have a few questions that i would like some opinions on. first, i used OPC on just because that was already checked. c4e says OPC off when burning at 2.4x verbatims, but do you think that only applies to that disc type? or does he say OPC off because it isn’t necessary for those discs. if you burn a verbatim at 2.4x with OPC on would it still be good? it seems to me that Optimal power calibration would always be better or equal but never worse. i also read online that some discs burn better at a faster rate, or rather slower isn’t always better, but in my case it is working. do you guys think these discs would be safe on xbox live? if my burner can verify the disc no problem, then the xbox should be able to do the same thing right?
