Derek, I hate to beat on the dead horse/SD , I hope you are using a low level formatting, i.e., the option took at least 7 to 8 min, right, as long as NOT the quick format. What does it say on the HP format, after low level format? You have to shut the program and re-start in order to read it correctly. If the reading is NOT approx 31G, the low level formatting is NOT working, or it does NOT work on your card. From your ebay link, 100% positive feedback from 568 customers. I did a random check, of the 1st 10 feedbacks, 8 of them returned the SD said it did NOT work, gave a + feedback as they eventually received the refund. Interesting, so the working rate for the card, is at most 20%! Apparantly, the 100% feedback is for good communication and fast refund, NOT for the card [FEEDBACK cut] I think I will take a pass. Edit: I have NEVER seem such a 100% positive feedback!!! It is a joke! bun
