For raw sector by sector copying, yes, open both drives with '@'. But, if the drive geometries are different in any way, do not write sector 0 until the last.
(To make things faster, I usually did the 2nd sector and up for the first track by sector, and did the rest by tracks, and lastly doing sector 0).
