V3 sd card not recognized after power off or reboot

  • Check the disk 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 Wyze App is a Quick Format

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.
