How long should Boot Camp formatting selecting drive take? I'm trying to install Windows 7 using Boot Camp Assistant. Now the boot camp is on task "Formatting the selected drive" and it has been going on three hours and it is not even on the half way. How long this task should take normally, or is this normal? Or is task frozen somehow?
The formatting should only last seconds. The behavior which you're experiencing is not normal at all.

I would cancel the installation and verify the disk.
