I read the other thread about the 4 and 8 GB cards and ordered an 8GB. I install it and run the card format utility and my 8320 only recognizes 3.8GB available space. OK, I can live with that, but the 8320 will not recognize the card as the storage device for the camera. In fact, I can't get it to "find" the card. I have done a format, reformatted, and pulled the battery three times to re-do the process just to make sure that I had not left anything out.
