. But I've seen a couple of good comments about the G-Drive from a company I am not familiar with, G-Technology.
Does anyone have experience with the G-Drive and especially with their 1 TB Q model?
Yes, I received the 1TB model for Christmas (my wife reads my Amazon wish list...) and have it working with my MacBook Pro on the Firewire800 interface. I know what you mean about the sleep mode problems. I previously had purchased a Buffalo quad interface external 1TB drive (identical specs. to the G-Drive), but whenever it went to sleep, the Mac could not wake it. The easiest way to fix it was to toggle the power switch - resulting in the "Unexpected Removal" warning - which was not a solution.
I now have Time Machine working fine with the G-Drive, and daisy chained the Buffalo unit on the Firewire800 interface (G-Drive contains two F800 connectors that allows a passthrough). The only slight negative is that the drive generates more noise than the Buffalo, but it's really not much. I located it under my desk on a hidden shelf, so that makes it almost silent.
Go for it!
