I was copying a rom file to my microSD using an usb adapter, and after that no flashcart could load the system files. I then tried connecting that microSD to my computer (with different adapters) and it gave me this error: "You need to format the disk in drive H: before you can use it." So apparently my microSD is corrupted. All I want now is to recover all my save files and roms if possible! Please, just tell me what to do in order to solve this problem. Thanks!
