How do I know if my SD card is not working?
In almost all situations, the SD card is damaged because the file system is damaged or the Master Boot Record is corrupted. The file system and Maser Boot Record are like bookkeepers to your SD card.
What is Master Boot Record?
The information in the first sector of a hard disk or removable drive is known as the Master Boot Record (MBR). It specifies how and where the operating system (OS) of the system is stored in order for it to be booted (loaded) into the computer's main storage or random access memory (RAM).
When you access your SD card from any device, the device operating system will access the files through the SD card File system and MBR. Hence either of them is damaged, and your SD card will be marked as corrupted or simply inaccessible.
Here are a few signs which confirm that the SD card is damaged or Corrupted. Prior to considering the following scenarios confirm the memory card reader status. Only after confirming that the card reader is properly working, consider the following situations.
- Unreadable SD card while trying to access the data saved on it. An error message encounters stating, cannot read from the devices.
- SD card will be displayed as a RAW drive. (SD card will be displayed in the windows explorer but in the details, it will be marked as RAW)
- Windows Explorer will display a Blank SD card or an Unsupported file system.
- Format error after inserting the card into PC. Either Computer will prompt a box asking you to format the SD card.
These are a few of the most common signs that say that your SD card is damaged. However, there are a few complex and not so often memory card errors. Which are:
- CRC errors while copying data from/to a memory card.
- Memory card with “SD card won’t format on Windows” error
- SD card will not be displayed even on Windows explorer or will not be recognized on the computer
