Hi G-Tech Support. I have a 4TB G-Drive with 2 Firewire 800 and USB 3.0 ports. When I format my 4TB G-Drive using the Firewire port in Mac OSX as Mac OS Extended Journaled, format is successful. Then when I switch to using the USB 3.0 port, my Mac would show a message the drive needs to be “Initialize” or formatted. Or vice versa, when I use the USB 3.0 port to format the drive as Mac OS Externded Journaled, format is successful. When switching to Firewire 800, I get the message needs to be “Initialize” or formatted. My problem is similar to this guy https://discussions.apple.com/thread/4561330
Another note, I also have another G-Drive, 2TB also with 2 Firewire 800 and USB 3.0 and the G-Drive works fine. Regardless if I formatted the drive on either using the Firewire or USB 3 ports, the 2TB G-Drive’s Firewire or USB 3.0 works Ok after formatting. Can anyone suggest a solution?
Below are more Info to help fix the problem
