It's guaranteed not to. Having n extra bits, you can detect n-bit-flips and correct n/2-bit-flips (provided you use an optimal code). These extra bits can flip, too, so if you have m >= 1 data bits and any finite number n of extra bits, it's possible to have an undetectable n+1-bit-flip. -- If you can't remember, then the claymore IS pointed at you.
