Well, my last few burns from the new Litey have been better. Maybe bad media.
But I was really just wondering if burning software uses embedded info in the image file formats to make any calculations or assumptions about the burn- and if something was out of whack, whether the problem would be detected before a burn or maybe throw something out of whack later on. Because as far as I can tell, the power error in imgburn halted progress before the disc was written to, while Nero just went full speed ahead and churned out coasters with no warning.
And this is just hypothetical, but if a drive is failing and getting out of spec, wouldn't different data patterns place different electrical stresses upon the burning mechanism? i.e., a slight mechanical fault in the laser on/off mechanisms would make the drive responsive enough to burn "all zeros", but not to rapidly cycle 1010101?
