Hi hope someone can advise. I am looking at external firewire 800 drives. Can I partition the external into two volumes and do the following? One volume will be used as a Cloned Boot Drive of an older macbook. The other volume with be used as a Time Machine Backup of new Macbook. If the above does work, is it possible to have a setup (disk space allowing) where the Time Machine Back includes the mounted volume of the cloned boot drive? I assume (perhaps wrongly) that time machine can backup mounted volumes such as another external drive. I have been looking at the Imoga Max Mini and Ultra Max. If anyone has any experience of these, or any suggestions for other externals feel free to add your experiences / recommendations. eSata might be useful, but then that all depends on how quickly thunderbolt adapators/hubs come out - and wether these come out before consumer thunderbolt drives. Thanks.
