Hi Guys This is my first attempt on G4 although I have been following you for a couple of months now. I am new to MAC and have a G4 400 to which I have added a 250gig drive as part of an upgrade to a multitrack recorder. It installed and formatted with no problems, but....... the system sees it as a 130gig drive, is this a similar problem to the Windows based machine and what software/information do I need to sort out the partition problem. Thanks for all your other useful information Alaric London UK
