I have a 2gig Adata card from newegg 3 weeks ago. I used it in something other than my gp2x, so it was reformatted and I lost a gig, is there anyway to get this back?
this might be a silly answer (im sure your computer savy) but what file allocation table (fat) did you format it under. you should be using fat32. try again using fat32 or ntfs (not sure your device will be able to use ntfs though)
also go to properties on the card, tools tab and check now button - this will look for error and bad sectors on the card
