Please, I really need to save the files on these two SD cards, all my backups are on them. For some reason when I put these two SD cards, (a 4GB and 2GB SanDisk) in any android phone and even mount them to my computer, I get this error, however the phone detects other SD cards perfectly fine!! It's not like I even tried rooting the phone. Someone please help me! It would be much appreciated!! (I use an Evo Shift 4G for Sprint if it helps)
