Mark, AFAIK, you can boot from any attached HD that the iBook will recognise (and obviously it will need to also have a functioning OS installed). The differences between models of HD's and Cases are mostly one of looks, performance (this is where the oxford chip counts=faster than others for transfer rates), amount of space and cache, type of comms connections (i.e. USB, Firewire and soon USB2) as well as price. The only difference the OS makes about what volume to start from is in system prefs under startup disk. Or you can use a keyboard shortcut to determine what system to start from at boot time. I've not tried it but I imagine that one could even start from a network volume (i.e. ethernet or airport...anyone tried this?) HTH, Cheers, Richard --
