I had very bad experiences with old lead data's CD-R's as well... the old "Silver Blue Professional" discs, 16x speed discs.. they were a nightmare!
Only one word: DATA LOSS. they didn't seem to last longer than a year! without being used a single time.. :o :o
Still got 2 empty ones lying around, can try them for audio but the chances are very small that my HIFI can read them properly 'coz it hates the old "Silver Blue" dye-types... it had probs with the old Verbatim pastels 40x rated (TY which are great for data) too. :eek:
Don't burn any important data on these ones unless you got a backup! :bigsmile:
