I've already had that happen so badly that I had to replace the cable. Usually I just get a mild wave in the cable from a poor wind that is put under tension. The secret to avoiding that is to never wind the cable in without tension on the line. If you have to do so, then unwind the cable well past the loose part and rewind it with tension before using it under load. Winding a cable under heavy load on top of loose wraps is a sure recipe for kinks and tangles.
The real damage I did to my cable was when it came off the self-releasing snatch block the wrong way and jammed between the pulley and the back plate. One of my two self-releasing blocks was prone to this - it has since been modified to prevent it from happening again. Normally, I would have just cut out the damaged part and shortened my cable. It's 230 feet long, and I rarely use the whole length. Unfortunately, this one happened almost exactly in the middle of the cable. Since I quite regularly go over 115 feet, I had to replace the cable.
