SD card won't open, windows card prompts to format

[coolcommando54]

I recently went on a month long expedition to malaysia. My friend had a gopro and has 64gb worth of footage he gave me, along with other cards. This card however now refuses to open, and I get errors such as:

 

G:\ is not accessible.

The volume does not contain a recognized file system.

Please make sure that all required file system drivers are loaded and that the volume is not corrupted.

 

I'm pretty sure he has it backed up but I definitely want to save this if I can. I gather that formatting it like one of the prompts I get would delete everything? What can I do to save it?

Try to use recuva or some other software to try to get the files from the sd card.

Formatting clears the card, so dont do that.

Just installed recuva and it says it can't scan because it's unable to determine file system type.

Ok, then the card somehow got corrupted. Is there a way in recuva advanced options to choose a filesystem?

Not that I can see.
