If you want your data CD's to work flawlessly with every burner and to last long, don't use CD-R's that I say I don't recommend.
The plain Sonys that don't say "COLOR MIX" on the packaging are made by Lead Data and are the lowest of low quality, producing killer amounts of C2 errors at every speed.
