Also, do I always need to cover one hole on a 3.5" HD disk when using it in an HD-capable drive? Or does the disk or the OS notice it's been formatted as DD and then treat it accordingly?
In *most* applications, the extra hole in the HD floppy changes the operating parameters of the drive itself. (There are exceptions, notably on some IBM systems of the PS/2 variety).
Of course, on a DD-only drive, the drive is blind to the extra hole. One of the things you have to keep on eye peeled for when handling a bunch of 3.5" floppies--to read the disk on an HD drive, you need to cover the hole.
