Check the settings in the Finder's preferences, and whether the Disk Utility is able to see or repair the drive. If it still won't show up and doesn't need repair, click here and follow the instructions.
Assume you are trying to connect via USB? Powerbooks don't put out enough juice on USB to power many devices. So, some won't even power up, and some may power up and still not be recognized. There are a few solutions:
1) Get a power supply for the external hard drive
2) Get a powered USB hub that your hard drive would plug into
3) Get a special USB cable that has two plugs to use both Powerbook USB ports
4) Connect via Firewire. With a Powerbook, this is preferred, because you can boot from a Firewire device, which you cannot do with a USB-only device.
