I installed a 3TB drive in my WindowsXP64 machine last year. I was having problems seeing all 3TB. I ended up using GPT for the drive and made a 2TB and 1TB partition and things were fine.
I'm moving to a Windows7-64 machine now. To my dismay, when i moved the GPT drive into the new machine, Windows7 will not read it and immediately says "This Drive Must Be Formatted". This is driving me crazy because I was trying to avoid large copy sessions across the network (old computer to new computer) so I moved all my inportant stuff to this 3TB drive with plans to just physically transfer the drive. But now Win7 can't seem to read it.
From everything i've read, it seems Windows7 should have no problem with GPT. Anybody have any idea what's going on and how to get around it?
