Write Speed Miscompare

Recommended Posts

Why do you think I got a Write Speed Miscompare error? This log says 12x is a valid speed. The log also says 18x is valid, but the Verbatim media has 16x as it's rated speed on the disc logo and package, is that a bonus speed? Imgburn changed my selection to 4x. This only happened on one disc, others burn fine, but just wondering.


Also, not sure what "AWS" means on the speed selection means, but on another computer, I had it set for AWS, and maximum burning speed was 22x! Will/should Imgburn burn faster then the rated speed if it can? Thanks for all of your support!

Update ImgBurn.


That disc was damaged in a previous failed burn and that's probably why your burner ignored ImgBurn's 12x write speed command. Try with a brand new blank disc.


AWS is Automatic Write Speed and, if it's not configured by the user, it defaults to MAX write speed, which of course depends entirely on your burner's capabilities.

thanks. yes, a previous attempt failed, but the Imgburn window still said Status: Disc Empty, so I closed everything and tried again with the same disc. I was basically just wondering those questions, but I burn a lot with Imgburn, and rarely have an error, and the movies always play great!
