re-booting from an external HD?

My iBook G4 has been set to Network start

up for some time because of a faulty motherboard. Since the HD is full I`ve bought a replacement 320 GB internal HD & because Leopard is no longer available I`ve cloned the original HD to my Lacie 500 GB external HD. An old iFixit manual suggests holding down Option whilst re-starting to bring up the "Boot" menu. I`ve been trying to test boot up from the Lacie unsuccessfully. Holding the option key I`m been taken to the blue screen with the curly arrow & straight one & a symbol of the iBook`s HD but no sign of the Lacie either here or in the start-up section. The Lacie is a USB HD..Can anyone tell me how to re-boot from the Lacie??

iBooks will not boot from an external drive via USB, only FireWire. You would need to put the drive in an external FireWire enclosure, and connect that to your computer via a FireWire cable for it to show up as a bootable device in option mode.

Also, if your machine is defaulting to network boot, you should be able to resolve that by resetting the PRAM.

Thanks, i have another older Lacie external HD which i`ve dismantled but the pins on the new 320 GB HD seem to be different to those on the connector in the Lacie. I`m sure I`ve done this proceedure before of cloning my original internal HD across to my present 230 GB internal HD. The 320 GB drive I have is a WD Scorpio Blue. This was my next worry as to whether upon dismantling the iBook, the pins`d be the same. I might have to send everything to the local Apple centre though it`d be nice to know this wasn`t futile because the part isn`t compatible. I thought it was the right part according to what I read about it..?

I imagine the newer hard drive is a SATA drive, as opposed to IDE, which iBooks use. A SATA drive doesn't have pins, but instead had a solid cartridge-like board, whereas IDE drives have two rows of pins. A SATA drive will definitely not work inside an iBook...the only way it will work as a boot device is if you get an external enclosure for it that supports FireWire.

This has two rows of pins. I'll check again later but I was hyperconscious I might be bending pins if I forced it though a certain pressure is needed to push the connection on.

This drive has four pins at one end separated from the others & in the very middle there's one pin in the row above & none below..

I think the connector / pins inside the enclosure are a little different. I keep getting deja vu like I've been through this all before..!
