I don't think you can do any real harm clipping them around any wires, unless it's a wire you actually want to carry a high frequency signal on.  Sometimes they work, sometimes not.

For a hard drive supply cable(4 wires) I would clip one around all four wires and slide it around to see if there is a place along the cable that cuts max noise.  If the cable is long enough I might try wrapping it back through(same way it came in) and see what that does.

I don't think I'd try putting one around the data cables.
