A formatted SD card is ready to be set up again for use in a compatible device. SD Memory Card Formatter applies the SD Association’s file-system specification to SD, SDHC, SDXC, SDUC, and microSD cards.
SD card formats
The formatter is made for cards that follow SD standards, including SD, SDHC, SDXC, and SDUC. It also supports microSD cards. Formatting follows the SD Association’s file-system specification, giving the card a format intended for use within the SD ecosystem.
Choose this tool when preparing an SD-family card for reuse or setting it up for a device that expects an SD-standard format. It handles the formatting task; it does not preserve the files already on the card.
Card detection and formatting
After a card is connected through a compatible slot or reader, the program detects it and displays card information alongside its available controls. If the card does not appear, the Refresh control asks the application to check again.
Selecting Format starts the operation and removes the card’s existing contents. Copy off any files that need to be kept before formatting, since the operation is destructive.
- Connect the SD or microSD card through a compatible reader.
- Use Refresh if the card is not detected automatically.
- Start formatting with the Format control.
Protected card regions
Some SD, SDHC, and SDXC cards contain a security-protected area. SD Memory Card Formatter leaves that region untouched, so formatting with this application does not erase or prepare the protected area. Access to that part of a card requires a separate tool, typically supplied by its manufacturer.
