If you are only concerned about the data being accessed, I suggest you find a firm that has a magnectic table(the sort that grinders use to hold metal objects still) put in on that and turn it on. That will wipe any data that is on the drive.
Baring that you will just have to allow them to send it back as it's under warranty and for most firms it becomes their property after they replace it.
