as far as I understood, your burner manages the sheep test, if it burns the files and you are able to copy them back in another drive.
So, tried it with my DVD-burner benq dw 1620 pro. Though it could copy the files back to hdd itself, this didn't work for other drives
Since every CD-Burner should manage efm-coding, I tried the same in my old sony crx-140e. Interesstingly, this time I was able to copy the files back on the benq.
So, does this really mean that my old sony does SD3 !?
