ShredIt X | Mac: How to Erase a CD-RW

Before disposing of a CD-RW or giving it to someone else, we recommend that you securely delete all the files you don’t want the next user to be able to recover. Using ShredIt X will make the CD-RW safe to re-use because it will erase the data on it so it can’t be recovered.

  • If you don’t need to secure delete the files on the CD-RW, you can use the erase function in the operating system instead. This will delete, but not erase the data on the CD-RW disk. You can find instructions on the Apple Web Site “Mac OS X: How to erase a CD-RW disc”
  • This procedure works with any CD-RW, but not with a CD-R (regular CD). To ensure that the data on a CD-R can’t be recovered by someone else, you need to damage the disk so that the data can’t be read. We recommend the following two methods:
    • Using a sharp instrument, scratch up the data surface of the disk so that it can no longer be read, or
    • Place the disk in a plastic bag and then bend the disk in half until it snaps. (The plastic bag will protect you from flying plastic shards.) If you can’t get the disk to snap, try using a hammer or mallet.
