What is a write-protected SD card?

A write-protected SD card is an SD card that has been set to prevent data from being written to it. Users can only access and read data on the SD card but can't edit, delete, or modify files or add any data. This protection safeguards important data on the SD card from accidental edition, deletion, or overwriting.

Usually, full-sized SD cards including Standard SD cards, SDHC cards, and SDXC cards have a physical write-protection switch. How about the write-protected Micro SD cards and mini SD cards? Micro and mini SD cards rely on external adapters or third-party software to achieve write protection.

Write-protected SD cards are mainly used on cameras, camcorders, media players, gaming consoles, audio recording devices, etc.

How does write protection work on an SD card?

Most SD cards have a small physical write-protection switch on the side. You can toggle the slider between two positions to turn on or off write protection for the SD card.

When you toggle the slider to the position labeled LOCK or a lock icon, you enable write protection for the SD card. In other words, the SD card is now read-only. You can only access and view data stored on it.

When you switch to the opposite position, you unlock the SD card. Now, you can read and write to the card seamlessly.
