How to Format USB for Tesla Dashcam & Sentry Mode (30 Seconds)

Quick answer: Format your USB drive to exFAT and create a folder named TeslaCam. That's it.

Here's how to do it on any device:

Option 1: Let Tesla Format It (Easiest)

Your Tesla can format the drive for you:

  1. Insert a blank USB drive into the glovebox port
  2. Go to Controls > Safety > Dashcam
  3. Tap Format USB Drive
  4. Wait 1-2 minutes

Done. The car creates the TeslaCam folder automatically.

Option 2: Format on Windows

  1. Plug in your USB drive
  2. Open File Explorer
  3. Right-click the drive β†’ Format
  4. Set File System to exFAT
  5. Click Start
  6. After formatting, open the drive and create a new folder named exactly: TeslaCam

Option 3: Format on Mac

  1. Open Disk Utility (search in Spotlight)
  2. Select your USB drive in the sidebar
  3. Click Erase
  4. Set Format to exFAT
  5. Click Erase
  6. Open the drive in Finder and create a folder named: TeslaCam
Important: The folder must be named exactly TeslaCam β€” capital T, capital C, no spaces. Otherwise Sentry Mode won't record.

What USB Drive Should I Use?

For Tesla dashcam and Sentry Mode, you need:

  • 128GB minimum (256GB recommended for longer storage)
  • High-endurance rated (regular drives fail from constant recording)
  • USB 3.0 or faster

Good options: Samsung Bar Plus, SanDisk High Endurance, Samsung T7 SSD.

Avoid cheap generic drives β€” they'll fail within months.

Where to Plug It In

Model Best Port for Dashcam
Model 3/Y Glovebox USB-A port
Model S/X Center console or glovebox

The glovebox port is specifically designed for always-on recording.

Still Not Working?

If your drive isn't recognized after formatting:

  1. Try a different USB port
  2. Reboot the car (hold both scroll wheels for 10 seconds)
  3. Make sure Sentry Mode is enabled: Controls > Safety > Sentry Mode

Takes 30 seconds to format, saves hours of troubleshooting. A properly formatted high-endurance drive is the key to reliable Sentry Mode recording.
