I've had a few cards that are just annoying: there is a (Windows only)
utility from the industry consortium that "does" SD which is often
recommended and has recovered one or two for me - especially some
which appear to have an Apple Mac partition ID
SD cards - unless particularly strange physical sizes - are probably
cheap enough that you can write it off to experience.
SSD drives in SD card format - don't know.
And yes, I've a "blessed" SD -> MicroSD card adapter which seems to work
better than most of the others and a good Sandisk USB2 -> SD card holder.
It is a bit random as to what will work and what doesn't.
Just my €0.02 of experience,
All the very best, as ever,
