OK, I have now spoken to Customer Services and I explained the problem to them. This is the conversation:
Clauber B.: Hello, thank you for contacting SanDisk. My name is Clauber B… Please give me a moment while I look into your question.
Liva B.: Hello, thank you for contacting SanDisk. My name is Liva B… Please give me a moment while I look into your question.
Clauber B. has left the chat.
Liva B.: Please be advised that SanDisk RMA policy is to replace products under warranty, once the defective product is received in one piece. We do not review data.
Dave Sibley: Thank you. I appreciate that but I do feel uncomforatable sending you this card with personal, confidential information on it. As a possible solution, would it be ok for me to cut the card into 2 pieces which will destroy the information the card contains?
Liva B.: Alright, we will make an exception for you to return the product broken in pieces.
To provide you with a sense of security, you may break the SanDisk defective device and ship it back to us.
Also, please print out and include this update so that our Receiving Department does not reject your RMA.
Dave Sibley: Thats very kind. thank you for your understanding.
Liva B.: You are very welcome.
Is there anything else I may assist you with, Dave?
Dave Sibley: No thank you. You have been very helpful.
Thank you for contacting SanDisk, and have a great day, Dave.
Liva B. has disconnected.
