My 4TB Solid-State Drive (SSD) isn't working with my A329/A329S/A329T series dash cam. What do I do?Updated 20 days ago

This typically occurs when the solid-state drive does not have the correct file format, partition table layout, or partition map for the dash cam, and the dash cam is unable to format the drive itself.

To get your VIOFO dash cam to recognize the SSD in this case:

Windows

1. Open Command Prompt as an administrator.
2. Type diskpart and press Enter.
3. Type list disk and press Enter to view all disks.
4. Type select disk X (replace X with your SSD's number) and press Enter.
5. Type clean and press Enter to erase all partitions.
6. Type convert gpt and press Enter to convert the disk to GPT.
7. Type create partition primary and press Enter.
8. Type list partition and press Enter.
9. Type select partition 1 and press Enter.
10. Type delete partition override and press Enter. This removes the reserved partition.
11. Type list partition and see if there is only 1 partition left, named as primary.
12. Type exit and press Enter to close Diskpart.
13. Unplug the SSD from your computer.
14. Plug the SSD into your VIOFO and format it on the device.

Mac

1. Format the SSD using Disk Utility, choosing the exFAT file system.
2. After formatting, unmount all volumes from the SSD, then launch Terminal.
3. In Terminal, type diskutil list and press Enter to view all disks.
4. Type sudo diskutil eraseDisk -noEFI exFAT NONAME /dev/diskX (replace X with your SSD's number) and press Return.
5. Once the above command is done executing, eject and unplug the SSD from your computer.
6. Plug the SSD into your VIOFO and format it on the device.
