3.4   Burning Backups of CDs/DVDs

You can use DropDMG to create exact copies of CDs, DVDs, and Blu-ray discs, for example:

To do this:

  1. Go to the Configurations tab of DropDMG’s Preferences window and set DropDMG to create a read-only .dmg image.
  2. Drag the CD or DVD icon onto the DropDMG window or use one of the other methods. DropDMG; it will create a device image of the disc and save it as a .dmg file.
  1. Eject the disc.
  2. Use the Burn… command to burn the .dmg file, making sure that Burn contents of disk images is selected.
  3. DropDMG will ask you to insert a blank disc; after doing so, click the Burn button.

Tip: DVDs are faster to access than CDs. If you burn a DVD copy of an emergency boot CD, your Mac will boot approximately 25% faster from the backup than from the original CD. This can be a savings of a couple minutes.
