I've been stuck at 2.89 GB for that past half an hour. Brand new drive; got it because the old one had an "invalid node structure" and whatever reformat, repartition, disk repair, etc. wouldn't work on it. So now with this new drive, a FantomDrives Gforce Megadrive that I got from newegg sounds OK. It automatically formatted when I asked Time Machine to back it up (OS Extended Journaled Case-sensitive). Using USB 2.0. Any tips/suggestions/insight on what might be going on? Thanks.
