I just called Sandisk and they say they have a new card version that corrects the problem. 1-866-SANDISK (726-3475)Sandisk Tech says that the new package will show that the card is made after March, 2013 (don't know if that includes March, but probably does), and it should be corrected. Some older than late 2012 reportedly are ok.  Who knows.They even say that they will provide a free UPS return label.Of course, you are taking a risk as to whether the problem is really fixed, so keep backups.  I don't know what I would do.
