SDFat Error Codes

I am having some software-side trouble getting SDFat to work on the Photon. I had it working as recently as a few weeks ago, so I know this library works. I’ve been getting a variety of error codes, and I would like to know more about what each one means.

I’ve dug through the source files for the libraries, and found some clues, but there doesn’t appear to be enough in the comment to deduce what each error means.

Does anyone have a list of what each SD error code means?
