I had a similar problem with a used 128 Pro plus.
Bought it from a colleague with an F5 also. Put is in my camera that then said it could not read it
and did not want to format it.
tried several times in camera nothing worked.
then pulled the card and reformatted it in my laptop.
Camera was able toe read it then, did a new reformat in camera and it works flawless ever since.
seems that they are finicky.
also use the older blue cards and some are not able to do high speed work an others are.
with the orange (budget cards) I never shoot HFR because they just can't handle it
My Camera act a bit weird sometimes, now I don't have the card problem anymore but the other day I had a E95 312 error but I removed the battery and switch off the camera and it came back to normality not sure if is because the camera was brand new and need some time to break in like the new Car
