If you want all the data on the disk eradicated, this will work. And unless you're data is so valuable that people are out there just waiting for the opportunity to apply extreme data recovery measures just to get some fragments of what used to be there, doing it once is sufficient. If the data really is that sensitive and that valuable, then do it twice. But more importantly, nothing is going to be faster than this, except perhaps degaussing the unit. Besides, it's not going to take days. It would probably be done by now if you'd started the "dd" command when you sent this mail.
