Portable Harddrive For Powerbook G4?

I have an old Powerbook G4. Do they make a portable hardrive that I can save items onto? I tried to buy one but it required two USB ports and on the G4 the USB ports are on opposite sides of the computer. The cords coming off the portable harddrive would not reach to both sides at the same time. Basically I need a portable harddrive with one required USB port or one that has two long cords coming off of it. Can you guys help?

Thanks,
Nick

G'day and welcome to the forums.

For a G4 look for a Firewire external hard drive case as G4's will not boot from USB.

Can you list me to a few examples because I'm still not sure what I should be buying.
