Before using the new disk or SD card, to make the operating system recognize it, you must first write some magnetic marks to each sector on the disk, you can use the data on the disk under the Operating System. This process is formatted. Formatting can be straightforward as dividing your disk or SD card into several blocks before you can store data in it. Each file occupies a different "cell. Data cannot be stored without formatting. Currently, the SD card has been formatted and can be used dire
