If you want a set-and-forget TeslaCam setup in 2026, go for storage that is built for constant recording, not a cheap promo USB stick.

Formatting on the Tesla screen is the simplest path if you are already in the car.

You can use one drive for both music and Dashcam, but it works best with two partitions.

Dashcam unavailable usually means the car cannot read the USB drive, not that the cameras failed.

Tesla does not publish a hard size limit for Dashcam drives, but 128GB is the practical minimum if you want more than a few hours of history.

Tesla's manual calls for a USB drive that can sustain at least about 4MB per second, and many cheap drives cannot hold that speed.
