Ok, I searched all over the forum but did not really find an answer to this on (if there is, please point me in the right direction and I will call myself stupid for not finding it ). Here is my issue. I swaped sd cards to a 16 gig card. My 900 had problems with the card right away, I was not able to copy much on it, so I formated FAT32 under windows (I know, the develish system). Card shows but still has problems, like I can't write photos from the camera application to it. So now my real problem. I decided to put my old 2gig card back in. After I did, most of my images do not show up with preview (see attached screenshot). I did a hard reset of the tracker, but still the same. Funny as is, the last 2 pictures on the bottom of the screenshot show fine. One was taken before I took the card out and the other one after I reinserted the card. Any idea? Thanks for the help.
