This is the critical step that prevents the TESLACAM partition from getting corrupted and causing the dashcam to stop working. Right-click the drive and go to Properties.

On my computer, it appeared on drive I:, on yours it's likely to be a different drive letter. Find the drive letter that your USB drive appears on. Insert your new USB drive in the computer and open Windows Explorer (Windows Key + E). The Tesla will not read this file system so we have to delete it and create the partitions we want.ġ. Your USB drive probably comes already formatted with the NTFS file system. Do not use this utility to format the TeslaCam partition, this is what causes the corruption that stops the dashcam from working.

You will need the 3rd-party Fat32Formatter utility to format the music partition, as Windows cannot format a partition larger than 32GB in FAT32.

This USB drive will have all data deleted during this procedure, make sure you have moved any important files somewhere else. A decent choice is the SanDisk Ultra Fit drive, as it's physically very small, relatively inexpensive, and has good (though not outstanding) performance. I recommend a USB 3.0 flash drive, as these drives are typically made with flash memory that is faster than USB 2.0 drives. I wouldn't recommend this procedure on the Server operating systems (2008, 2008R2, 2012, 2012R2, 2016). I've only tested this on Windows 10, but it should work all the way back to Windows 7. I have not had the dashcam stop recording when the drive is prepared like this. I believe this method gets around this problem as well.

Like others, I've also had the issue where the dashcam will work at first, then the USB drive appears to become corrupted and the dashcam will no longer record. This procedure shows you how to take a USB drive and partition it into 2 partitions so that you can use the drive for both music playback as well as the dashcam feature in version 9. I've tested a lot of configurations over the past 2 days and I think I've finally come up with a method that works reliably.

It's been reported that you can partition the USB drive into two separate partitions and make a single USB drive work for both dashcam and music, but this is not the easiest thing to do on Windows. Without some type of work-around, that would use both USB ports in the front of the car, leaving you with no USB port for phone charging. I find the requirement for a separate USB drive for music and the v9 dashcam feature to be annoying.
