Frumpy -
I can't say as this will be any help or not, as I am running OS 9.2.1 on an iMac DV 400. However...
1 - Power up iBook.
2 - Power up external firewire HD, and wait 30 sec.
3 - Plug firewire HD into iBook.
Icon of HD should appear and HD should be accessible at this point.
To put away:
1 - Drag HD icon to trash.
2 - Unplug HD from iBook.
3 - Turn off HD.
Never turn off HD if connected to iBook.
Never disconnect HD if HD icon is on the desktop.
I also would not advise using sleep function with HD attached. A nice feature of an external hard drive is that you can keep it off and unattached when not in use. This way it will be totally unaffected by anything that may happen to the main hard drive. Good luck.
