     Some C-64 games produced drive gyrations that were kind of gross.

     Apple II game protection was, mostly, less noisy. It's hard to say
whether or not playing lots of copy-protected games would have messed up
Disk ][ alignment because so many disks were routinely cracked and saved
without the protection.

     The worst effect of protection was that, too often, it ended up
bombing your originals. Origin's "Tangle Tales" is a good example of
using copy protection which seemed guaranteed to eventually eat its own
diskettes.
