We could probably do with one of these to stop people asking the same questions. If you can think of anything to add to this, then post it up and I'll add it in. What is XGD3? A new disc type for Xbox 360 games. Why is it causing problems? The capacity of DVD+R DL discs is 7.96 GiB. XGD3 ISOs are 8.13 GiB, so they won't fit on. But the latest version of ImgBurn already burns the discs to 100% using the truncate option! This is true, but it's not burning 100% of the ISO. There are 2 options in the current version of ImgBurn when you try and burn an XGD3 ISO: - 1. Overburn. This tells ImgBurn to try and fit 100% of the ISO on the disc, regardless of the fact that the disc is too small. Once the progress bar gets to about 97%, the disc runs out of usable burning space and ImgBurn can't continue, so you get an error. You can then finalise the disc and most XGD3 games will still work. 2. Truncate. This tells ImgBurn to fill the disc to its capacity and ignore the fact that what you're trying to burn may be too big to fit. When the progress bar gets to 100%, what that really means is that the disc is 100% full. It doesn't mean that you've burned 100% of the ISO, as you've still only burned 97% of it as that's all that will fit on. Both of these methods give the exact same result, but if you choose the truncate option you don't have to click through several error screens. Why can't we just burn all XGD3 games using the truncate method? That method was working OK until Forza 4 came out, which features new LBA hash checks. As only 97% of the ISO is burned on the disc, the game fails these checks. More games will almost certainly use these checks as time goes on. So what is Burner Max? It's a firmware for particular Lite-On DVD burners created by c4eva that allows you to burn the full 8.13 GiB ISO on to standard DVD+R DL discs. That means that games such as Forza 4 no longer fail the LBA hash checks. Which drives does it work with? You need one of the following Lite-On SATA drives: - Lite-On iHAS124B Lite-On iHAS224B Lite-On iHAS324B Lite-On iHAS424B Lite-On iHAS524B Lite-On iHAS624B The B at the end of the name denotes that the drive has the required MediaTek chipset so it can be flashed with Burner Max once it's released. There are also A and Y models. A is also MediaTek but is untested. Y models contain a NEC chipset and will definitely not work. All of these drives are essentially the same, but the higher up models have more features like LightScribe and Smart Erase. Unless you specifically want a burner with those features, you can just go for one of the cheaper low end models. There are also other DVD burners out there that are rebranded Lite-Ons and you may already have one of the required drives without realising it. Google for info on that, cos I don't have a complete list of all drives that are rebranded versions of the above iHAS drives. Which one of those drives should I get? In terms of hardware, there's really only 2 types: - Lite-On iHAS124B Lite-On iHAS224B The 124B has the same hardware as the 324B and 524B. Similarly, the 224B has the same hardware as the 424B and 624B. You can convert a 124B to a 524B and you can also convert a 224B to a 624B, so there's very little reason to buy anything other than one of the 2 low end models. A guide to cross-flashing a drive to a higher model is HERE. I've never fitted/replaced a burner in my PC before. Is it difficult? Nope! Crack open your PC case and you'll see where your existing burner is. You may have a spare drive bay to add a second burner, or you may have to replace the existing one. The burners are held in place with a couple of screws that screw into the sides and the only cables you have to plug in are a power and SATA cable. It's a really easy job and anyone can do it in just a few minutes. What do I do with the drive once I've fitted it? You need to flash it with the Burner Max firmware. Here's the firmware for all 6 drives, the tools required to flash it, and a guide in PDF format: - http://www.multiupload.com/D3IPJY7CIW Will the drive still work for reading/burning CDs and DVDs when it's flashed with Burner Max? Yes. The burner will still work as a regular reader/writer and retain all of its other functions. Which brand of discs should I use? If you're using the current truncate method that only burns 97% of the ISO to the disc, you can use whatever discs work for you. Verbatims are recommended due to the quality, but if TDK or Memorex or whatever have always worked fine for you, then you can carry on using them. With the Burner Max method, it is recommended to only use Verbatim discs (either MKM-001-00 or MKM-003-00) as these are the only discs that burned and verified without errors in c4eva's tests, although he didn't say what discs he'd tested. MKM-001-00 discs are rated at 2.4X and MKM-003-00 discs are rated at 8X, so that's how you can tell them apart in stores or when ordering online. Personally I've always used MKM-003 discs anyway as they allow for a faster burning speed and this is also true with Burner Max as you can burn them at 4X as well as 2.4X, while MKM-001 discs can only be burned at 2.4X with the Burner Max method. Do I need to reburn all of my XGD3 games using the Burner Max method? Nope, unless the game uses the new LBA hash checks (Forza 4, for example) and you've already burned it using the truncate method. If you do need to reburn, you will have to use the original ISO or re-rip your original game. You can't rip a backup that was burned using the truncate method and create an ISO with it because only 97% of the ISO was originally burned on it. That would defeat the object of using Burner Max and your burned disc would still fail the new checks. Do I need to reflash my 360 with new firmware? Nope. You need LT+ 2.0 or above (LT+ 3.0 is the recommended firmware), but if you have that already you're OK. What's the new method for burning the discs? Check the burning guide, HERE.
