Hi all, I have just installed Leopard on this Powerbook. Everything is working ok except the 2 usb port unable to powerup USB external hard drive. USB mouse works perfectly on both ports.

When I plug in the external hard drive I could hear ticking noise, on a side note the external hard drive work perfectly well on other machines running Win-XP and another Macbook.

Any idea or tips welcome.

Many thanks in advance.

You had already started a thread about this machine. You could have just added more info on the other thread. Is it a 12",15", or 17" powerbook? Also, its been a while since I've looked at a powerbook. Is there usb ports on both sides of the machine? I can't remember.

The Powerbook G4 have only 2 USB ports

It is likely that the single usb port is unable to deliver enough power to spin up the drive, let alone allow it to be accessible to your OS. I would suggest maybe using a powered USB hub, or sharing the drive from another computer over the network.
