Yes I tried that, and it doesn't allow me, though I have an older disk image on wich I keep my safe stuff wich works very well.
The thing is that I've tried to create such a disk image on a new external firewire drive (Seagate with 300 GB storage ). When I try to create a disk image it says either that the device is busy either that the disk is to big.
What do you guys recommend? Or maybe you could tell me how can I put a safe password on a partition?
This is what I am...
