Hi @cf7 Loading the firmware might expose bad cells but wouldn’t cause the corruption. Here are a few suggestions:
To test if its a corrupt uSD card.
- Remove the uSD from the camera and test it in your workstation.
- Check the disk (uSD) with the command line C:\Windows\system32>ChkDsk X: /r Where X is the uSD card
- Format the uSD card FAT32 and un-check the default “Quick” option so it can mask out bad cells.
Note: The Format from the App is a Quick Fromat
Quick format just marks the partition as “formatted” and destroys the journal that keeps tracks of the files and their locations on hard drive.
Full format will clear files completely from the partition, rebuild the file system, volume label, and cluster size, and scans partition for logical bad sectors; that’s why full format is slower than quick format. Wyze devices must always use the FAT32 format.
- Preferable to use High Endurance cards in your device.
