@Solla-topee so last card broke yesterday, message something like abnormal expansion capacity, after that SD broken can only read no write, it lasted 1 month and 1 week, from 128 gb is 78 full, write only on motion not continuous. Can not test that card as can not write.

Model c510w hardware version 1.0

  @Solla-topee this are all broken, one more is in camera itself, all are same bought same date same store, on 3 cameras running for over 1 year without issues, on other 3 breaking constantly, the cards get locked, can not be formatted on PC with any tool, only read

  @Solla-topee I have had the same experience with SD cards that worked fine for a few months and then are rendered usable because they're not looping and rewriting. They are completely filling the storage capacity of the card.The Tapo camera write protects the SD card so that they cannot be reformatted on a PC. Reformatting through the Tapo app - camera setting - does not work either. I have two cameras and both of them have corrupted SC cards and are useless for home security when they will not record.

please forward me any corrective action that the escalation team deem successful in correcting this flaw.

Many thanks !

In July 2025, I purchased two Tapo 3K 5MP Outdoor Pan/Tilt Security Wi-Fi Cameras. 
1. 
Firmware Version 1.3.3 Build 250923 Rel. 59794n

Model: C530WS_AB0B

Hardware Version: 2

2. 
PNY P-SDU512V32100PX-GE 512GB Premier-X Class 10 U3 V30 microSDXC Flash Memory Card

Amazon (same as Tapo cameras)

I had to delete and reinstall the app to clear the cache after formatting again did not work. 
this message appeared when logging in to the app and opening the camera:

Failed to Initialize

This microSD card has an abnormal expansion capacity. Please try a new microSD card.

Got It       Learn More

Attempted again to format. It always starts, gets 5%, stalls, jumps to 75%, then 80%, then crashes. 
Error Messages is always:

Failed to format your microSD card. Please try later. OK
 

I hope the details of my experiences are helpful in finding a solution to what appears to be a widespread problem. The problem is not found until you go to playback and download and see that it has not been recording because it overfills and doesn't rewrite over in the leading process. 

Thanks again,

Thank you for your reply. As stated previously, the card can not be formatted on a pc, nor in the camera. 
When inserted several times, the camera recognizes the card but will not format it, as described in detail previously, crashing at 80% mark. 
 

I cannot complete the H2testw because the Tapo camera write protected it and that can not be removed. I tried. 
 

I do not see where in the settings or elsewhere that I can change that aspect or see an option for encryption.
 

I have followed all the steps provided in your previous communication. I have gone through multiple attempts in Command mode on the box to remove the write protection - unsuccessfully. 
 

I did explore the suggested as cards prior to purchase in July 2025. Perhaps, I made a mistake or there was a change.
With that said, I've never had any trouble with pny cards in other media devices and brands from digital to video, security, or game cameras to quickly name a few.

Tapo camera is the outlier. 
 

I replaced the first SD card that failed after 1 month, in September 2025, with an Amazon Basics SD card. That card is still functioning well as of tonight. 

I will reexamine the list of suggested media and proceed in replacing another rather expensive 512 card. 
 

1.  I have turned on diagnostics in the camera. Can you tell me how to share that information?  The app was showing 3 recordings earlier this evening but those are not showing now. I'm hoping there may be information created in the diagnostics report. 
 

2.  Please explain why some brands are incompatible with Tapo cameras. 
Also, I do not believe it is an SDcard issue as, Victor, another poster is/was using the Kingston cards with 50% failure rate.
