If it's the same problem mine had, then nothing is likely to help. If the controller on the card has decided to write protect the storage because of impending doom, there is nothing you're likely to achieve with most user accessible tools.
Get in touch with Sandisk - I found the staff to be brilliant. After a couple of emails back and forth, I had permission to drill through the memory ic on the card to protect my days, and an RMA number to return the product. Sadly I have to return it to the Czech Republic (awkward as in in the UK - somewhat expensive) - but is less hassle than dealing with many retailers.
