SD card, also known as memory card, is a small, portable, and functional device that may be used to expand storage capacity in a variety of devices, including digital cameras, Android phones, tablets, and so on.

However, repeated insertion and removal of the SD card, especially without safe ejection, is likely to result in file system damage or faulty sectors on the card. If your SD memory card is inaccessible or becomes corrupted and unreadable, don’t panic.

- If you insert the SD card into the card reader, but your smartphone or computer does not detect it. The words “Memory card error” or “Damaged memory card” may appear.
- If your operating system gives you read errors like “SD card not available,” it’s time to upgrade. The file or directory has been corrupted and is unable to be read.” “Error reading / writing to SD card” or “Error reading / writing to SD card.”
- If you can’t add, save, remove, or copy any files on the SD card but can view the complete contents of the SD card and get an error message that says “write protected,” it’s because the SD card is “write protected.”
