Thanks Steve, First, about partitionning disks, i was told to split my HD into 3 distincts parts: 1 OSX;2 OS9 system disk;3 OS 9 Audio disk.... Is that a clever solution to adopt, supposing that i don't have any external HD at the moment ? Fortunately my IBook boots into 9 and i am personnally looking for a Motormix remote control (already tried it...Amazing!!!) Now, considering i would buy an external firewire drive (thanks for your suggestion), do you know if 40Go firewire drives exist (cos i've never seen any in France). To conclude, you're not not the first to tell me that stuff about PT6, so thanks for confirmation. Regards
