If you are having difficulty with viewing and updating your Log Box, saving or viewing WRL log files it may be due to a problem with the Micro SD card, and formatting the Micro SD card may correct the problem.
If you are able to see the Log Box in Windows File Explorer as a USB drive (as shown below), you should be able to format directly while the Micro SD card in inserted into the Log Box.
If you are unable see the Log Box in Windows File Explorer you will need to use an external card reader to format the Micro SD card. In this case you will need to remove the micro SD card and format it using a USB card reader and your desktop computer.
- Remove the Micro SD card from the Log Box v3
- Insert the Micro SD card into an external card reader connected to your PC
- The Micro SD card should appear in Windows as an external hard disk (see image above)
Regardless of whether you are formatting the card in the Log Box or an external card reader, the steps are the same as follows:
- Right click on the micro SD drive in windows and choose 'Format'

- Under 'File system' select FAT32
- Leave all other default settings unchanged
- Click Format
- Once formatting has completed you can remove the Micro SD card from your PC or card reader, and re-install it into the Log Box.
