Back when I owned a Model S, someone mentioned that Linux's ext filesystem works (for Music). I forget which version I used, but I believe it was the then-latest, ext4. Try some conservative settings on a Linux native ext4 or ext3 filesystem, and see if that works. Maybe use the "case insensitive" formatting option, if available (I forget if that's a mount or formatting option). Also, try different capitalizations if it doesn't work with the first try. You could even make a directory name for each capitalization and see which one the Tesla uses. I do not know if ext is still supported for music or for the dashcam; it wasn't documented at the time. I find this typical of Tesla: they have undocumented capabilities that they don't support. They should go ahead and support and document it.
I used my Linux system to format the USB stick into ext. I think I even selected a Linux-native partition type or no partition type (you can try both), such as GRUB or whatever the latest was at the time, but be conservative there, knowing that MS-DOS is bad so anything you get to work is probably (not necessarily) better than MS-DOS partition tables. However, I temporarily bought a shareware ext4 filesystem extension for MacOS, and that worked too. Someone with a Linux system here please confirm this works before those with only MacOS buy the shareware ext4 filesystem, because otherwise it would be useless.
My USB music stick always worked flawlessly with the ext* (I think ext4) filesystem on it in my Model S.
After a couple of hours using dashcam, it stops working. The "dashcam" icon on the main display now includes an "X" instead of a red dot.
Looks like the file system got corrupted. Plugging and re-inserting the drive didn't help. When I swapped in a new drive as the current one, the dashcam icon shows up with a healthy red dot.
Here's what MacOS DIsk Utility says:

Huh. So, I wonder if Tesla's computer will accepted, use, and automatically repair a journaled ext4 filesystem; then you could practically remove the stick in-use and everything would be dandy, I think.
There was also three fsck-related files, so the car is actively trying to repair the file system when it mounts it (presumably when it wakes up).

That's good news for my theory of using ext4 with journaling turned on
what usb drives are you using? Dont cheap out on them because dash cam recording is a strenuous activity (its constantly writing to the usb drive when the car is on) and will kill most drives. What happens when you get in an accident and find out your usb drive went co
I bought a small microSD usb adapter and using a
128gb Samsung Endurance Pro microSD.
That makes perfect sense!
The USB stick I used for music in my Model S was a known-high-quality well-working USB stick, which I then had to hunt down and specifically purchase. My effort was rewarded with a stick that I still own and never failed nor had flaws.
I'm using this USB stick (it's really tiny!): SanDisk Ultra Fit 64GB USB 3.0 Flash Drive - SDCZ43-064G-GAM46 . I bought a pair so that I can always leave one installed in the car if I ever needed to review recordings from the other.

That's the same one I used, recommended from here at TMC, for music. However, I don't think we did a lot of write-cycles using Music; are you sure it works well with dashcam?
