For those who are experiencing sd card problems after updating from firmware 2.2.1.1135 to the current 2.2.1.1223 firmware. I really regret updating. These are new cams and during setup, the app tells you to update, I did on the first 2 cams and had sd card not being recognized error. Through much troushooting this is what I found out: if I take the sd card out of the updated cam and put it in the cam with 1135 firmware, the sd card is recognized. Reseting the cam with the new firmware did nothing and reformatting the sd card did nothing. Wyze tech support had no solution and would not roll back the firmware as others did in the past. Here is what did work.
I did have an issue with my sd card that windows couldn’t fix. I used diskgenious to fix the card. If windows will format you sd card then don’t use diskgenious, just format with windows.
I reformatted the sd card to exfat using diskgenious on my pc, ejected the card and reinserted, As suspected windows detected an issue and suggested repair option. Repaired card successfully. Did a few more eject and reinsert to make sure everything was good with windows and just for good measure let windows do a quick format. After I was satisfied, the card was put back in the cam and formatted with the cam. The sd card is working now.
Could be finicky sd cards or firmware or both. The old firmware didn’t seem to be as finicky.
Word of advice: make sure to use the eject option when available and let Windows double check the sd card for issues by inserting/ejecting several times. Then, when the sd card is put in the cam, let the cam format the sd card. This needs to be done. The cam format prepares the sd card with wyze folders and data
Can’t comment on the issue or the cause as I don’t have one, but be aware that FAT32 is going to have very bad read and write speeds once it starts to fill up, especially on a 1TB card. It may get to the point where it cannot write fast enough, and navigating recorded videos will get very slow.
Good to know. May try reformatting later to exfat and seeing if the cam will recognize the card. I have one cam on a 64gb exfat and one on fat32. I didn’t notice any issues …yet. Was a very time consuming process to get whey in at. Wish I could downgrade to the 2.1.1135 firmware. That firmware has no issues with sd cards. If you buy a wyze cam, my advice is don’t upgrade
Have you tried formatting the card in a PC using the formatter from sdcard.org? Maybe it came with some sort of glitchy format on it - the sdcard formatter restores the card to official SD specs.
It could be a firmware issue with that particular cam, all my cams are running latest firmware and running exfat on the cards.
I believe it is a firmware issue with the current firmware . Old firmware isn’t finicky with sd cards. I did try the sdcard.org formatter. Very basic. Look at disk genius for sd card tools.
I did experience an sd card issue with the 1tb card formatted to fat32. It looked good initially but had playback error. I put a 32gb in the cam and formatted with cam. That card is formatted exfat and is good. I’m going to reformat the 1tb to exfat and see how it works. I was surprised it even worked at all since the max supported card is 256gb.
I reformatted the 1tb card back to exfat using diskgenious on my pc, ejected the card and reinserted, As suspected windows detected an issue and suggested repair option. Repaired card successfully. Did a few more eject and reinsert to make sure everything was good with windows and just for good measure let windows do a quick format. After I was satisfied, the card was put back in the cam and formatted with the cam. The 1tb is working correctly. Playback works fine now.

As stated in my first post, don’t use diskgenious if windows will format the sd card. I caused some errors while troubleshooting the sd card problems with wyze cam. As a result, windows couldn’t format or repair the sd card even with cmd. Diskgenious is a great tool to fix the sd card so windows cam format it. Saved a few sd cards.
Basic is good. The one and only goal of that software is to restore the card to “pure” SD card specs with a clean format, proper offset, etc.
The long format can be used to verify the card is in fact the size it says that it is, and sometimes even find and mark bad cells, but there are other tools that can do that too.
This goes for both windows and the cam (cam has an eject too). Powering down the cam or removing the card while it is writing will almost certainly corrupt the card to some extent.
I wonder if that 1TB card could potentially be fake or no good. Cards that large are prime targets. You may want to use something like h2testw or even just do a full overwrite format on it with the sdcard.org formatter (will obviously take quite a while).
Hard to tell if you’re recommending this tool or not but as I mentioned in another reply, I highly recommend just using the sdcard tool if all you want to do is get a fresh clean default format on an SD card. I can’t remember the last time I used anything else to format an SD card, and I even have used it with thumb drives (since they’re just SD cards in an USB adapter).
If that utility can’t do a full overwrite format and restore the card to good health, there is something wrong with the card. Using another utility to try to “avoid” the bad area by partitioning around it will just cause issues with most devices, which sounds like it did in your case too.
OK, personally I’d recommend the sd formatter before either of those two.
If it can’t format the card (try quick first, and if that doesn’t work or you suspect the card has issues, do a full), there is something wrong with the card. Diskgenius may be able to hide/ignore the errors but it will still cause you problems if they’re not properly marked by the sd card’s controller.
