The resolution on the SD Manage is in Gb + 2 decmil point. Wouldn’t the cam’s SD driver know the size down to the byte? The idea would be that the Free space changes after any Write. {{Equals (Value1, Value2)}} True/False
If both values are equal then the SD may be no good. I go sleep now. . .

indeed You are entirely correct there, that is a data integrity check, but I don’t know if our cameras have the ability to pull this off as I don’t know how much resource it would consume, but in going there, it seems like they would already have that capability even if it’s not utilized but I don’t know how often they do it. In my previous answer I stated Y as even after our format the card showed as full, this showed that even though the card was known to be empty the camera recognized it as full as it had not refreshed. Naturally the old adage of restarting it indeed fixed the issue but therein lies an issue as well. So it seems like if you format a card whatever memory cycle looks at that should also look at the data checks as well but I don’t know if it would or if it’s capable. This is where I lack the nurdery needed

All good discussions on SD cards.
I just think something is buggy with the hardware. I saw only one minimal issue where I had to reformat a micro sd, and that sd has been working since early 2019. I use a standard Sandisk and Samsung 32GB card without any other issues on all my v3 and v2 cams.
Again, I see it as luck of the draw of the cam you purchase. Why do some cams have SD card issues and I do not?
I could see long endurance maybe helping with continuous recording, since I only use event recording. I record numerous events in a day.
Another Wyze puzzle.

I was just thinking about this as a Wyze future enhancement. I’ve been caught finding out that my MicroSD card is dead or defective when I go to review past footage many times over the 5+ years of owning Wyze Cameras.
I think at the bare minimum, on the “Devices” screen, show a MicroSD card symbol for the cameras that the MicroSD card is actively recording. At least this would be a quick visual queue with minimal app programming.
Using the photo below as an example:
- MicroSD Symbol w/Green Dot –> Activly Recording to MicroSD Card
- MicroSD Symbol w/Red Dot –> MicroSD Card Error - Not Recording
- No MicroSD Symbol –> No MicroSD Card Installed / Detected.
The app really should send a notification when the MicroSD card can no longer Read/Write at the minimum, and the MicroSD card has not been ejected. It would also be nice if the App had a way of running a quick Drive health test on the camera (like Windows CHKDSK or Linux FSCK) that could be scheduled and report back and log bad blocks, and report if there is an increase in bad blocks detected.
