I use an iBook G4 & worry a lot about backing it up. All that music, bank statements & lord knows what lost in an instant if something goes wrong. So I invested in Intego Personal Backup which is great for backing up to an external drive. But what it wont do is back up a .dmg file to CDs. It gets half way through & blobs out everytime. Can anyone recommend something to burn my .dmg file to CDs ? It is 3.5GB. Best regards Martin.
