My G-Drive Q 1TB is silent (dead) and is not visible on my mac. It's 3,5 years old. When I press the power on switch (on the G-Drive): -The activity lamp (on the G-Drive) blinks half a sec, but then remain dark. -The green lamp (on the external power supply) turns off. My 3 years warranty has just expired. Planned obsolescence? :-( How do I check what part is defect? a) external supply b) driver card c) internal disk Additional info: I use it as TimeMachine Backup connected with Firewire 800 to my Imac. I have tried USB connection as well, but with the same result. I have tried it on my MacBookPro as well, but with the same result. The disk inside the G-Drive Q is a 7200 rpm Hitachi produced in 2008.
