When I buy a new hard drive I format it to wipe all the unnecessary stuff off that comes pre-loaded and takes up space. Photos can then just be dropped to it, yes. However, since you're on mac you might consider an inexpensive little program called SuperDuper which will do the backup automatically in whatever schedule you choose. Note: drag and drop won't make a bootable disc so if you want your backup disc to be bootable you must mirror or clone your main drive.
