Ill try to sum this up as simply as possible in chronological order.
1.) SD card dies
2.) New sandisk card formatted
3.) Old data extracted and placed on new card file for file
4.) New card loaded works perfect
5.) Attempted monthly nandroid backup and pulled error 31.
I know standard protocol is to format the card but i see no need to since it was already done. Is there a way to reinstall nandroid so that it will work properly again?
