Windows uses a base-1024 to calculate capacities while Mac uses a base-1000, e.g. in Windows, 1MB = 1,024K kB = 1,048,576 bytes, while in Mac, 1MB = 1,000K kB = 1,000,000 bytes.
Why is free space after formatting within between the SD Memory Card Formatter and macOS Disk Utility or Windows Drive Properties dialog?
The SD Memory Card Formatter formats the card without consideration of the operating system’s own file system driver. Once the formatting completes, the operating system’s file system driver mounts the card and creates hidden directories and files for its own purpose. The difference of free space right after formatting as reported by the Formatter and as reported by the operating system’s own dialog comes from those hidden directories and files creation.
You can enter 11 ASCII characters or 5 characters in Japanese double-byte character.
Quick format deletes all the file/directory entries by initializing file system parameters of the card, but it does not delete the data written in files. Overwrite format deletes file/directory entries by initializing file system parameters of the card (same as with Quick format), and erases all data by overwriting the user data area completely. The Overwrite format takes more time to complete than the Quick format method.
