Hello,

Thank you for taking the time to share such a detailed description of your experience, and welcome to the community.

First, we would like to clarify an important point: since the 32 GB microSD card can be detected, formatted, and used normally on your TC47, this indicates that the camera itself is functioning properly.

Regarding the two 128 GB microSD cards that could not be formatted, we kindly suggest the following：

Ensure there is no physical damage (e.g., bends, scratches) on your SD card.

    1. Make sure both the camera and Tapo app firmware are up-to-date.

    2. Power off the camera, reinsert the SD card several times, then power on the camera and try again to format the SD card.

    3. If the SD card was previously encrypted in another Tapo camera, insert it back into that camera and disable encryption: Tapo app > Camera's Device Settings > Storage & Recording > Local Storage > Encrypt microSD Card > Decrypt.

    4. Insert the SD card into another camera or a computer with an SD card reader. Check if the SD card can be formatted/recognized by the computer/another camera.

   5 Use third-party software such as H2testW to verify the SD card integrity:How to Spot and Test a Fake Micro SD Card

For more details, refer to this FAQ: What should I do if the SD card cannot be formatted/recognized?

If the problem persists, please provide the SD card test result to us.

Best Regards

Thank you for providing the methods to test the sd cards.

With all these methods, the sd card is genuine and not defective.

I also would like to clarify an important point. This card can be used in another camera, ICSEE brand model A32 without any problem. This also prove that the card is genuine and not defective. 

You have not explained why your TC47 camera can detect a cheap and fake sd card but rejected the expensive and genuine card. 

Please review your TC47 camera software and I strongly believe that your software needs improvement. 

I am willing to send this card by courier service to you to prove that it is a genuine card.
