KIWIIANO Appears to work, but I ran into fish-hooks. My MacBook's TM ext drive initially refused to mount when plugged into a G4 iBook running Tiger. When it did mount and I successfully instructed the MacBook to access it via Airport and ethernet, TM started to recreate the backups from scratch then ran out of room. It's a nominally 160GB drive to back up a 120GB internal with about 84GB used. T
