Kate in answer to your question, there can be a problem in moving a drive like that from Mac to Mac. Some macs require special little files, called Enablers, to work properly. Within the range of Macs that can run OS9 (let's say), there are some early ones with SCSI on the motherboard but no USB or Firewire, others (more recent models) with USB only, still others with USB and Firewire; it can be a mess. In theory it can work, assuming a model-specific enabler isn't required and all extensions required by both machines are in place.<br><br>John<br>[color:red]I don't need no steenkin' signature!</font color=red>
