First off, thank you Lightning UK for ImgBurn! I've been using it for as long as I can remember! I mean back in the days when it did DVD Decrypting (wasn't there a name change back then?)!
So I have two Intel based computers with iHAS 124b drives with burnerMAX firmware;
1) Gigabyte GA-Z68X-UD3H-B3 (normal BIOS), Intel 6 Series SATA, Marvell 88SE9172 SATA, i7-2600k, 16GB RAM, HP 1260i C, iHAS124b (on Marvell SATA)
2) Gigabyte GA-Z68MA-D2H-B3 (UEFI), i5-3570, 8GB RAM, Intel 6 Series SATA, iHAS124b (on Intel SATA)
Neither one of them will burn a decent XGD3 without making 5 or 6 coasters first. I've spent the better part of 2 weeks reading and trying everything! I still couldn't burn more then 2 good disc in a row. I picked up a Optiarc AD-5280S Plus put in box #2 reset the ImgBurn settings and burned a disc over the network, reset the computer that was sharing the ISO while it was burning, continued burning it 35 minutes later, and had a PI of 19/.89 and PIF of 2/.08 (Kprobe max/average)! the HP1260i with the payload performs just as poorly as the ihas drives too. I don't want to give up on my iHAS drives! So here is a list of everything I can remember trying in hopes that someone here might have the magic silver bullet!
All test have been done with both MKM-001 and MKM-003 Singapore disc on both computers with no noticeable difference.
Tried the C4EVA guide settings (with and without OPC, 2.4x/4x, with all advanced drive settings on, with OPC cleared before each burn, [5 burns with OPC, 5 without], Box #1 in IDE mode & AHCI, Box #1 with default SATA driver & Marvell driver, 512 meg buffer)
Tried default ImgBurn with settings it recommends (usually 4X with online hyper tuning disabled) for the burn.
Things I know I haven't tried
Crossflash to another model number IE 324, 624, etc.
Moving to Intel sata on Box1. This is not really an option due to the way the HDD's are configured. Both computers have the same Intel SATA controller and the drive on box #2 is on the Intel.
Stock 124 with payload

So do you guys see anything I missed trying?
