how long should it take?

You should be able to copy cd's in about 10 min at 8x. thats what I use usually..... if your comp is fast enough, the cd burning should be able to go at 8x no prob without failing.
I generally use Nero Burner at 8x or 12x and it copies the cd onto the HD and then burns it so It's safer.
I generally don't recomment burning cd to cd, since it tend to slow down the burning process and often ends up messing the cd up.
