I think Seagate has taken their eye off the ball. I've just upgraded to Lion and now cannot connect to my Seagate Blackarmour NAS drive. Checked their site and their software is only up to Snow Leopard. Maybe this is also your problem. I wouldn't mind but I believe Seagate HQ is also in Cupertino. Don't they talk to Apple?OK, so this makes no sense at all. I just upgraded to Lion on a new 2011 iMac.
