I came home from a visit with Jenifer and Michigan. I had a great time and her kids are the best. We had a tough time burning my SD cards. So I called Sandisk. I explained my problem and they offered me to return, them maybe they are deffective. Later that night a supervisor called to talk to me and told me to send 2 back. I just got the replacements for 7 of them and now my Apacer works.
