Had similar problem with the 2nd 512 MB Sandisk CF bought in Costco. I'm very upset as I lost some photos during my travel abroad. Should have asked for compensation when I returned it.
On the other hand, the first 512MB I bought in Costco works perfectly fine. I guess Sandisk does not have good quality control.
最初由 fad 发布 I don't remember they asked for memebership card, however, I always use Costo AMEX card for purchasing and they refund it directly to my AMEX.
