Start up from the Install CD that came with the iBook by holding down the c key as the computer is starting up.

Choose Reset Password from the Installer menu.

Select your Mac OS X hard disk volume.

Set the user name of your original administrator account. (Not the "System Administrator (root)" account.)

Enter a new password.

Are we talking about a FireWire drive? They are the only external drives with which I have any experience (and the only ones from which you can boot with a Power PC-based Mac).

You hook the FW drive up with a six-pin to six-pin FireWire cable. It should mount on your desktop.

Are you wanting to do clones from which you can boot, or are you just wanting to use the external FireWire drive for additional storage? You can partition and format the external drive from Applications > Utilities > Disk Utility. Choose to format as HFS+ Journaled when creating your partitions.

If you're wanting to do clones, SuperDuper! seems to be the application of choice around here, and it's what I use.

Thanks Ronda!
I was just able to reset the password of my account on an iBook G4! 🙂
