ECC Does nothing to prevent your server from dying in a fire after that police chase, either. However, replication is an effective solution to the problem you describe:

Whenever data is read, you read from more than one replica, and then compare them. If one of them has been corrupted, its hash won't match and you'll know it. You can then write out the correct data to the node with the error. This is very easy in systems like Riak.
