• If you see the black screen on your system, which is having an error message that says, "SD card is not accessible. The file or directory is corrupted and unreadable,". This is enough as a hint that your SD card is corrupted.
• You know your SD card is corrupted when the photos in the SD card are missing. If you are unable to get your pictures, you know where the problem is.
• When you are using an SD card on a PC, it is detectable properly and still brings the message "SD card is not formatted. Do you want to format it now?". This brings you the clarification that your card is damaged or corrupted.
• Another symptom could be when you try to look for the SD items in your system or camera and can't copy them. Furthermore, an error message comes saying the disk is "write-protected," and then your SD card is damaged.
• The SD card doesn't let you add, remove, or save anything in it when it is damaged or corrupted.
• When you try to use the camera, and it turns completely black. When the SD card seems to be so slow, it's time to understand that your SD card is not healthy enough to work properly.
• Another error message on your system could be "Read/Write error on SD card," and no folder in the SD card opens. This denotes that your memory card is not able to be read by the system.
