Ercole: I don't have the same MO drive as you, but I'll tell you what I did to partition disks in my 230MB Olympus drive. I used good ol' /stand/sysinstall. If you run it, choose Custom from the first menu, then Partition. It will give you a list of drive devices from which you can choose od0 (by highlighting it and hitting the spacebar). Once you put the slice(s) on it (or "dangerously dedicate" the whole disk), hit the 'w' key to write the changes to the disk. You are then either popped back to the menu or to the disk labelling program (I forget which). In the disk labelling program you can create one or more partitions on the disk. I hope this helps.
