My mac needs to go in to apple for a few weeks and the "genius" told me to buy and external drive and back up to it. I'm using Disk Utility to make a disk image of the drive in my Powerbook. Right now I am booted from the external firewire drive. I have tried twice to make a backup and it's working fine until I come back and it says "adding resouces" and waiting for a password. I enter my password and hit ok but then get an error 39. Any ideas? Sorry if this is messed up i'm in a hurry for work. L8.
