Recover The SD Memory Card Data

My SD Card is toasted.

It happened when I recorded my music video cover, a song called "Kolam Susu" by Koes Plus, but I used Musikimia arrangement.

I used to record my music performance on Logic Pro and the video on my Canon EOS M6.

I'm a multi-instrumentalist, I played music instruments all by myself.  So my workflow is like:

1. Record the drum.
2. Record the bass.
3. The rhythm guitar.
4. Guitar Solo.
5. Bass Solo, I improvised this part. 
6. Vocal.

In the middle of taking vocal part, suddenly the camera LCD went dark. I continue my vocal take because I always could lip-sync it later.

After my vocal take is finished, I grab the camera and, it shutdown by itself, uh oh...

I turned it on but it displayed a warning, something like "memory error", oh my...

I thought about my drum video record. It's always hard to "lip-sync" drum part; I have to rescue the SD Card data. And the journey's began...
