I gave up on using CR_RW shortly after getting the unit. The problem was not the failed burns, it was the unpredictable nature of losses after the burn -- just sitting in the case. After 6 months, I would guess that I had a 30% failure rate on discs that initially read OK after the last burn. Can't have that! Kinda defeats the purpose of a backup. At least with CD-R's, although I still often get "coasters" out of the oven, once it's on there, the data seems to stay put. Admittedly, this was early CD-RW software & media (4 yr old?). Has it gotten significantly better? -- or cheaper?? How much are CD-RW discs now?
