How can I safely erase the data from my SSD drive? I've seen a few pieces in recent days about how traditional "secure delete" programs fail to work properly on SSD drives, so what tools are available and useful?

As pointed out in a recent research article, there isn't a standard method for securely deleting data from a solid state drive. Hard disk drives have had this problem solved for ages, and can execute a secure delete by filling the space occupied by an incriminating file with zeroes or multiple writes of different characters. We'll go into why this approach and some other secure erase methods don't really work on an SSD, especially not for individual files, and then describe some approaches you might take to make sure all your old data is gone for good.
