Is it necessary to Format the SD Card?

If you do not have any important data, reset your memory card on the phone. Please be careful if you have important data. Back up your data to the computer.

What is the difference between CF and SD cards?

SD cards use their own protocol that will expand up to 32GB over 2GB with the release of SDHC (there were several 4GB SD cards, but not very compatible) and then support up to 2TB with the release of SDXC.

Form Factor Differences

The microSD form factor has a lower maximum capacity and does not have a write protect switch.

Performance Classes

There are different performance classes and cards can be produced in any grade, regardless of size.

Manufacturer Speed Determinations

Even within the same manufacturer, labeling may not tell you anything about the natural differences between form factors. For example, SanDisk may have developed a card in MicroSD format that is faster than the fastest cards on the SD card and labeled both "Extreme".

The Structure and Production Process of Cards

Don't think of these cards as the same, delicate pieces. The exact opposite. There are big variations in the output produced and the process is about efficiency and recovery.
