Error 02 is a bit different since I can't do anything with the memory cards currently either in camera or on comp. I am going to go pick up a new card reader and another card just to see if either fixes the issue.
If you're in West L.A. you can stop by my studio and play with it there. We have a shit load of cards 256 & 512's. Sometimes re-formatting on a Mac seems to clear shit out. When we go to Raleigh N.C. we take 400 CF cards, and I reformat them on a Mac, then each of 12 photographers formats their bunch again before they shoot, to make sure nothing in their camera will make it go ape-shit before the shoot. My boss has a bunch, and may be able to figure out what it is.
