I'm wanting to use my Pi as a dashboard camera and I'm wanting motion to save its files to the usb but it doesn't have permissions to save to it. The usb is currently FAT32 so I can plug it into a Windows PC and see the files. If making it ext4 will fix this I'll do it. The motion daemon needs to have access to the usb without a user logging in as the Pi will be headless. I have tried setting user to nobody in the permissions but I get Operation not permitted errors, even running as root user.

Any help will be appreciated.

You need to set the mount options when mounting the stick to allow the motion user to write to the USB stick.
Try these fstab options
/dev/sda1 /opt/yourmountpoint vfat -o umask=000 0 0

  • Did everything except for the -o and it works great. Mounted it to /media/USBNAME but had to create the directory there first
