Media write error, But

I suddenly started getting this error. They are rather cheap DVDs (not my choice) so I just grabbed another one but it failed in the same place. Gave up on the junk and tried a good quality one. Burnt no problem.

So just for a laugh I tried another one of the el cheapo ones, same error.
Except this was during a simulation. How can anything detect a media write error during a simulated write to write once media?

Remember that when media is being written, whether during simulation or during the real burn, there is no read going on (at least not a read in the normal sense of reading back the data). That is why you have to separately specify a verify operation if you want to actually check what has been written against what is on your hard disk.

(Golly, I just realized that DVDA doesn't have this option -- at least I can't find it. First CD or DVD burning program I've ever seen without it!!).

Anyway, back to your question. The error is an error reported back by the device (the DVD burner). If the media is bad, the laser mechanism won't get sufficient reflection back from the media, indicating an absence of "stuff" (technical term) on the recording surface.
