I am trying to upgrade the sd card from a 8GB to a 32GB. It is on my wife's STOCK EVO 4G. I tried formating the new card, fat16, copying the contents of the old SD card to pc, and then copy to the new SD. I did copy all the hidden files, etc. When I boot up with the new card, 95% of the photos are moved to the .LOST folder. I unmounted the cards before pulling them out.
Any ideas, guides, etc would be greatly appreciated.
