you're not being very specific with your settings... which advanced lite-on only options are you enabling or disabling and what burn speeds you're running at. its best to set a relatively high buffer in imgburn and make sure the image file being burned is not fragmented and the disk drive is not in use by any other programs.
I can watch my burns in real time and tell if they're going to be crap or not depending on how the speed fluctuates.
I've tried many combinations of Online Hypertuning/Force Hypertuning/Smartburn/Overspeed in the EEPROM along with OPC and BurnPROOF in ImgBurn to no avail. Six MKM-001 crap burns and 15+ MKM-003s. Tried the supposedly foolproof LightningUK settings (Force HT on/Smartburn on/Overspeed off/Online HT off and then 4x OPC off in Imgburn) with MKM-003 in both drives in both computers with no luck. One is running XP x86 with pretty much nothing on it (MSE disabled, no internet connection, no apps running, ImgBurn in realtime, tons of free drive space) and the other Win7 x64 with no foreground tasks and little in the background, 0% fragmentation on the drive and 40% free.
The MKM-003s are usually great until the layer break, where they've spiked from anywhere between 150 up to 2000 (yes, two thousand) for PI. The MKM-001s are higher everywhere else, but spike maybe 4 percent of the way in up to about 80, then 120 at the layer break, and then have a consistently worse second layer than gradually rises to a spike of 120 at the end. Same results in two different drives in two different PCs.
I refuse to believe that I got two bad drives/two bad batches of media, but I also know the PCs are good systems. I followed the guide for flashing perfectly (run upgrade, backup EEPROM and flash, write new flash), so I don't think it's user error, either. Really not sure what to make of this.
