@BLPasta are you encountering the error? Backup everything that's on the sdcard in your PC first.

Free Program for backup?

No, backup as in copy & paste everything elsewhere ASAP, since you've said that "sd was corrupted" . Now Backing up your saves with Checkpoint is highly recommended.
After that format it with Guiformat as fat32 32kb cluster size (64kb if you have a +64GB sdcard), then you can check if the sdcard is faulty or not with h2testw. If it's free of errors, put all the content back, and we'll see where we'll go from there.
