LIGHTNING UK!

Ah you can ignore that. The image changes sector form all the time and the image parsing code takes the form from sector 16 whist the drive's sector form comes from the first sector in the track. Within this image, sector 16's form is 'Form 1' and sector 0's form is 'Form 2'. This issue has been fixed for the next version.

You should have got the MKM-001-00 2.4x discs instead of those. If you don't want to waste any more, invest in a new burner that has no problem burninkg MKM-003-00.

Please read the 'pinned' thread here... http://forum.imgburn.com/index.php?showtopic=7860

A lot of Samsung / Lite-On drives now produce this error and nobody knows why. All you can do is hope that they fix it in the firmware someday. You should at least update ImgBurn though.

Seems to me as if it's failing due to this error... So your drive is producing a duff burn on the media you're using. You drive looks old to me because it doesn't support mandatory commands from the MMC specs, it's probably about time you invested in a new one.

Check for firmware updates and read this... http://forum.imgburn.com/index.php?showtopic=8000

Use additional drives when burning lots of discs and then the ones not in use will have time to cool down.

Slow speeds can be as bad as fast speeds, it all depends on the drive/firmware/media combo. The device buffer is ok to drop down lower, not all drives stick at 100% dead and the dips to 10% or whatever are probably just WOPC kicking in to examine burn quality and adjust the laser. It's the other buffer that shows if the program is able to read quickly enough from your hdd - and that's where defragging would come in. With Verbatim MKM-001-00 dye DL discs (made in Singapore) and a decent drive/firmware, you shouldn't have any problems burning. For the SL stuff I prefer Verb DVD+R's to their DVD-R's. I go with Taiyo Yuden for DVD-R.

Could be a good time for you to invest in a new drive? They're less than

Unless you're running into buffer problems (i.e. where they're not at 100%), defragging isn't going to make any difference. Defragging just speeds up the rate at which data can be read from and written to the hdd. If your disc are freezing at certain points then your drive probably isn't doing a very good job at burning them. Slow the speed down to 8x and make sure the firmware on the drive is up-to-date.

If the drive says it only supports 4x upwards then that other program is lying. 8x or 12x will give you perfectly decent burns on those discs.

Just ignore it for now, I've worked around a bug in their drivers ready for v2.4.3.0. The older drivers are ok though, as are the standard microsoft ones that ship with the OS.

Go into the settings and turn on 'Prefer Format Without Spare Areas', then ImgBurn will attempt to format using the 'Maximum Format Capacity' rather than the 'Preferred Format Capacity'.

You got a 'Write Error' code back from the drive, so it's saying it's having problems writing to the media. Are the disc made in Singapore? Verbs made elsewhere aren't as good. That drive must be getting on a bit now, have you tried cleaning it?

It's probably a bug in your drivers. Is the drive connected to an NVIDIA controller by any chance?

I gave up on Verbatim CD's a long time ago. Now I use nothing but the best... Taiyo Yuden A bus reset just means the timeout on the I/O command expired and the driver has reset the bus to recover from the hang. ImgBurn just uses a longer timeout - as you don't ever really want the bus to reset. If it does, you've got bigger problems.

As with everything 'optical disc' related, the 25GB value is the unformatted value and is using 1000 as the divider, not the true 1024. The real size would be: 25,025,314,816 bytes = 24,438,784 KB = 23,866 MB = 23.31 GB That's the *best case* senario. If the disc is formatted with what's known as 'spare areas' for error correction etc (part of the blu-ray standard), that size will be smaller still.

No, it doesn't (nor does it say anywhere that it does). ImgBurn burns as-is, because that's what burning tools do. If you want a (re)compression / (re)authoring / shrinking tool then you'll need to find one designed for that purpose.

What file extension does it have? All it means is that file extension is associated with a given program. It's not actually 'roxio' format.

Not always, no. It depends on how many cells/files can be lined up so as to satisfy the 'what makes a good layer break' criteria.

And you can't burn a 8GB image onto a 4.37GB disc.

If there's no MDS file ImgBurn will attempt to parse the image (assuming it's a DVD Video one) and present you with some LB options. You don't need to try and figure it out for yourself via that option in the Tools menu.

It's written to the MDS file.

Sounds like it's not a valid .DVD file. Open it in notepad and copy + paste what it says. If you see any mention of 'MediaType', remove that line and try again.

As I said before, talk to WD. Their flasher has to support your system and obviously it doesn't.
