To look at files on the PC, are you removing the microSD card, placing it in an SD card adapter, and inserting that into the PC card reader slot? If so, try this alternate way of looking at your files on a PC.
- This procedure eliminates the use of the SD card adapter and the PC card reader for viewing folders and files on the A119's microSD card.
- Record some files on the A119 and verify that they play back in the camera.
- Leave the microSD card in the A119 camera and, using the supplied short cable, connect the camera to a USB port on the PC (preferably a USB 3.0 port). When you do so, the A119 screen will turn blue and display the message "Mass Storage". Don't do anything to the A119.
- Now look in the PC Windows Explorer for a new drive (mine shows up as "USB Drive E:"). This drive should now display your A119 microSD card folders and files.
- When you disconnect the camera, best practice is to use the eject procedure available in Windows, as you should be doing for the card reader or any USB memory storage device.
If this doesn't show anything different, my last gasp advice after trying a different computer would be to try loading the latest firmware (A119S Firmware Version 2.2) from the Viofo Website Support page here:
http://support.viofo.com/support/solutions/articles/19000047224-viofo-a119s-car-dash-camera-firmware. Probably will help only if your firmware has somehow become corrupted. Manually default your settings using the menu selection "Default Setting" immediately after loading or reloading firmware.
