I just wanted to post that this fixed my problems too with ImgBurn. I'm hoping a "real" fix will come soon.
The problem only occured once I switched from IDE to SATA burner.
Before this, I "fixed" it by downgrading my SATA drivers to Windows IDE drivers, but that was causing other problems for me (couple BSOD's, and computer as a whole seemed slower).
Here are my detailed directions:
I copied the file wnaspi32.dll from \Program Files\Nero\Nero8\Nero Burning Rom, into my \Program Files\ImgBurn directory.
then I went into Imgburn, Tools/Settings/I/O tab. Under "Interface", I changed it from SPTI to ASPI.
Once I did that, everything worked great!
Relevant System Specs:
EVGA Nforce 680i SLI motherboard (nforce driver version 15.23), with latest BIOS
Nero 8
Imgburn 2.4.2.0
