Hi, I'm Independent Advisor, I'm here to help you.
When your laptop or computer doesn't recognize the SD card, you may try workarounds:
- Change the SD card reader and reconnect it to your PC.
- Change the SD card drive letter.
- Update the SD card driver.
- Run CMD CHKDSK command to fix SD card file system error.
- Restore SD card data and format SD card to FAT32 (smaller than 32GB) or exFAT (larger than 32GB).
If None of this works, try connecting a new sd card and check if it's working or "Not".
It might happen that your sd card is broken and can no longer be used.
I hope it helps, let me know if you need any further assistance.
Kind Regards,
Hania.
