LIGHTNING UK!

Indeed it would, 8x or 12x tend to produce the best quality burns.

Do you have a USB pen? Make that bootable and just copy the asus flasher and firmware onto it. They're much better suited to such tasks than optical discs are.

Post the log please, not a screenshot. Please also include filter driver information (look in the Tools menu).

Logically, there are no 'layers'. It's just one huge disc with BD media... even though phyiscally there might be 2, 4, 8 whatever layers.

Copy and paste what you see in the log window please. No it's not DMA related.

http://forum.imgburn.com/index.php?showtopic=8000 This is why I don't bother with 'pinned' topics normally, people just never read them!

It's either the discs you're using or just that your burner doesn't support burning DVD's at all - i.e. it's a CD Writer / DVD Reader. Look in the log window and see what the device scan reports.

That's why I posted it, yes.

layer breaks don't exist on BD media. You burn each layer from start to finish.

Windows just makes up the name it gives to drives, ignore it. You are using UDF 1.02 yeah? XP doesn't understand 2.5 / 2.6 without the use of a 3rd party driver.

That shouldn't make a difference, did the log of the original burn show any 'buffer recovery' related problems?

It wouldn't make them for a single layer discs (unless 'Working' and 'Working properly' are two different things. Without the MDS file daemon tools would mount them as an impossibly large single layer disc.

Maybe you'd have more luck if you used decent discs? i.e. Verbatim DVD+R DL 2.4x made in Singapore. After that, it's probably something with your console - and this isn't the place to be asking for assistance with that.

That's because the tutorial is about 2 years old and nobody ever thinks to update these things.

It contains the layer break information. It's also used when you mount the disc in something like daemon tools. Look in the options if you REALLY can't physically stand to have an additional 2k file on your hdd.

Fill out the information on the 'bootable disc' tab.

If that .dvd file had the LB value in it, you'd have the LB visible in the 'Sectors' line and you don't. Leave the setting on Calculate optimal.

ImgBurn's full format process writes zeroes to all the sectors, so if spare areas are enabled, the fastwrite option WILL speed it up (but only on the 2nd part of the format - the zero filling, the 1st is done by the drive itself) If spare areas are disabled then the program should be zeroing those sectors at 2x or whatever without the need for you to enable fastwrite. As mmalves said, the full format only needs to be done once (or if you change the 'spare areas' option). You can see the difference in size by looking at the preferred and maximum format capacities in the disc info on the right.

Unless there's some special header at the start / end of the IMG then it probably doesn't contain the LB position at all. Suggested layer break positions come from the program being able to align the Cell / File so that it starts on an ECC block and the size of L0 >= the size of L1. That's all there is to it.

Passing verify just means it'll play / read ok in the drive you verified in.... I guess it works both ways sometimes. ie. the disc might fail to read back in that drive but will work fine in another drive, or it'll work fine in that drive and fail to read back in another one. A 2x BD-RE with spare areas enabled and fastwrite enabled would probably write at 1.9x - 2.1x. A 2x BD-RE with spare areas enabled and fastwrite disabled would probably write at 0.9x - 1.1x. A 2x BD-RE with spare areas disabled and fastwrite enabled would probably write at 1.9x - 2.1x. A 2x BD-RE with spare areas disabled and fastwrite disabled would probably write at 1.9x - 2.1x. Turning off spare areas is a better approach than turning on FastWrite - of course it does mean repeating the entire format process again though Not only that, with spare areas disabled you get to use more of the disc for actual data.

It depends on if the data is important or not I guess. A miscompare or error on a video is probably no big deal but if I was backing up data, I'd want to know it could be read back afterwards without any errors!

FastWrite should only really matter to BD-RE. Your BD-R should always burn at their rated speed. To be honest, it's not ideal having it switched on as technically it's writing in 'streaming' mode (where data can be skipped if the drive can't keep up). With streaming enabled you really need to be using ImgBurn's verify after burn feature. You'd be better off formatting the BD-RE without spare areas (another option in the settings!) which basically disables the drive from doing Write + Verify for every Write command I send it too... only this time it's because without the spare areas there's no room for the drive to automatically reallocate damaged sectors to and hence it doesn't bother with its own internal verification part.

No reason really, it just makes it more obvious when it's stuck doing that for a while - i.e. in the case of bad discs that the drive cannot reinitialise. It's less important now that ImgBurn automatically cycles the tray and brings up other messages when there's a problem in this area.

Turn on file extensions within explorer, it makes life much easier!
