If anyone knows about this, I think it's Cirkutz. But personally I don't think you need this, just burn the image on a cdrw and you'll know whether your burner works. The only downsize is that I haven't been able to find any 80 minute cdrw's yet, but then again I haven't been searching too hard. Anyone know if these exist ?
Edit : whoops, didn't read your whole post. Woe unto me, I'm getting old and senile
. Anyway, I never heard of these but if they exist I'm sure one of the regulars will be able to help you.
