Well, you may be right about the COATING but I am not so sure about the
DATA. Also, I don't know about DVD but back to the Stone-Age when most
people were using CD (I don't remember if DVD bruner was available yet), and
some of the tricks to recover the expensive (it was pretty expensive then)
CD-RW was facing the SUN light (not so sure if have to cook in the sun or
just the sun ray) for hours to erase all DATA on CD-RW to make it usable
again.
I never had problem to try myself, but few reported saying the trick
worked for them (but very few reports). so, I also agree that DVD-RW has
much better build, better scratch resistance, stronger coating etc.. but not
the data. But only guessing as I have never had any problem with regular
DVD nor DVD-RW (or CD-R and CD-RW) besides scratches on the data size that
destroyed the disc.
