Fix Corrupted 1019 Memory Card RAW

I use a MadCatz 1019 memory card for my Wii. Because my brother needed it to put his massive MVP Baseball 2005 saves on for his GameCube until his new card that he ordered (same type) arrived, I put my Ocarina of Time save that I was playing onto an official Nintendo 59 card. When I moved it back onto my MadCatz, i tried playing Ocarina of Time. it said the card was corrupted and needed to be formatted. Since then I have tried dumping the card to a RAW file and have tried opening it with the Dolphin MemCard Manager but I get a "Directory checksum failed and directory backup checksum failed" error. Could anyone help me to either troubleshoot this error or take my RAW and edit it themselves to find where the corruption is coming from? This specific card has the saves of about 6 years of work so I'm willing to do whatever it takes to fix it.
