  • Question
    What if my CD was formatted to be compatible with a CD player? I can't delete the data on the disc, and I tried the steps above, but it won't work.

    When you "finalize" the CD to use in other players, it is no longer re-writable.
  • Question
    Can I rewrite on a CD that I purchased with content on it?
    Community Answer

    Depends on what type of CD you have purchased. CD-R can't be rewritten while CD-RW can be rewritten.
  • Question
    My "erase this disc" prompt has turned gray. How can I fix this?

    If you have a CD-R, it doesn't work. You need a CD-RW in order for this to be re-written.
