The naming convention made me think:
............
You're almost correct. The reason .............
Ok. Just a check: so if I name my files: [shooting date][prefix][number (6 digits)].CR2 is that too long with risk of filecorruption or damage to the memorycard? Especially shooting AI-servo 8fps?
Do not worry, you are not changing the file naming within the camera. Camera will still name is as _MG_XXXX.CR2 or IMG_XXXX.CR2. It is only when you are transferring the pictures to your computer that they get renames. Moreover, why use 6 digits? if you are adding [shooting date] to the then 6 digits are superfluous. Are you a professional who might capture more than 10,000 pictures on a single day, ever? If your answer is no to both then 4 digits are enough, if your answer is yes to the second part (more than 10,000 picture on a single day) then 5 digits will be enough (even if you are a professional you cannot possibly take more than or equal to 100,000 photographs a day).
