This is why I bought 200 DVD+R discs and 50 DVD-DL . Well, mostly because Netflix + dvd burner = an epic combo, but I only got the DL ones for discs that would NEED it. I really don't want to have to use DVD shrink to put an 8.4 GB disc onto just a 4.7 GB disc. (even though the program works extremely well and I am more than impressed with it) Anyway, I doubt anyone has any unbreakable files/folders that are larger than 4.7 GB. torrent folders can be broken down to single torrents, etc. And yeah, bobbias pretty much summed it up, too... While it may be nice using less discs, you're still putting all of your eggs in one basket. Remember, your invaluable data is riding on a piece of plastic with shiny piece of silver/aluminum on the backing about 10 pieces of paper thick. XD.
Scratches and data CDs do NOT go well together at all... In fact, I have about 7 or so windows XP discs burned (I claim fair use..........) simply because the windows installer had read errors on the disc (and just misplacing the CDs, or not knowing what the disc was later because i didnt care to label it)... And I'm talking about right off the spindle, directly into the burner, eject, into the other computer. Usually when I was fixing up other people's computers, I'd bring two of them, just for that reason. heh. But anyway...
