    Hi Amanda,

    To format your Macintosch CD you need to boot your Mac using another Disk. The OS will not allow you to do anything with your system disk if you boot the computer using it. You always need to boot using a CD or another HD to be able to format or reinstall Mac OS.

    If you got the original CDs with your Powerbook you can reinstall Mac OS using them and format all the disk starting from scratch. The original CDs (or DVD) installs even the iLife apps.

    I hope this helps,

    Hi Amanda,

    I have made a mistake in my previous installation. In the first sentence is MacintoschHD not CD.

    Another point. If the Powerbook that you have bought originaly came with Panther or Jaguar and you have a CD or DVD to upgrade to Tiger, you will not be able to install the original iLife. So it will be better if you install the original one formating everything and then you install Tiger keeping the contents of the MacintoschHD.

    One other way you can do it if you have another mac handy is to boot the one you want to format as a target disk (boot it holding down the T key), then connect it to the other mac with a firewire cable.  It will appear as another disk which you can format using Disk Utility (in your Utilities folder, in the Applications folder).  This is one way to nuke it if you don't have the install disks, but then you're left with a machine that kind of sort of doesn't do anything!

    Otherwise do as above, boot to the CD (boot holding down the C key), then when it asks you how you want to install (upgrade, new install, etc) just tell it you want a new install which will delete everything.
