Planning for failure
by: Joe

A CD is only about 20% as reflective as a true signal mirror. The platters from a HDD will quickly corrode wherever you touch them and will rust. You wouldn't go rock climbing with a rope that was on 20% as strong as possible or drive a car with brakes that are only working at 20%.

signal disk
by: Tim / Nomad

A friend of mine took an old hard drive apart the other day and inside were two mirror polished aluminum disks. They were about the same size and weight as a compact disk. They have a hole in the center to help aim it also. And they would blind you.

Not that effective
by: Leif

Be aware of that a CD is not as effective as a plastic signal mirror and definitely not if you compare it against higher quality mirrors. Yes, it is free but I would not recommend a CD as your primary survival-signaling device
