I have windows XP and am having the same problem with my SD card. I went to properties, tools and I did the error check. It did it's thing and said the SD card was repaired but when I put the card back in my BB and take a picture it says "file not found" and I am unable to save any pictures etc... PLUS I still haven't got back all the videos and pics that I lost when my SD card had the error. PLEASE HELP???????
