Do not buy these blank cds! I bought a spindle because they were so inexpensive and now I see why. The first 50 or so only had maybe 3 or 4 failures when recording, but then I got down to the bottom 50. I had about 12 out of the first 25 of those fail, so I moved from my laptop to my desktop to see if that was the problem and the very same thing happened. I had another spindle of office depot brand cd-rs and continued to burn the same day after the Dynex had expired and didn't have one failure out of the first 15 or 20.
