I believe I said, "... CD-RW media is usually only readable ...". Isn't your "... often only..." close enough to "usually only"? Chuckle, chuckle. However, in my very limited experience, I have yet to find another system that would read a CD-RW disk created on my present system (TDK CDR8432) or past system (BTC drive, as I recall), but my experience is certainly not all-encompassing nor definitive nor absolute. I've never had two systems with identical CD drives + CD-burning software such that I could ascertain transportability of a CD-RW media between the two, but I expect it would work. Regardless, I stand by my recommendation that, in general, one should not consider CD-RW media secure or transportable. It is sort of handy, though, isn't it? :-)) Tom
