Zero issues since 42.4 with dashcam feature. Works great now.
Here’s my setup:
SIIGUSB 2.0 2-Port Hub
Samsung MUF-64AB/AM FIT Plus 64GB - 200MB/s USB 3.1 Flash Drive
Also have the 1st gen Nomad charger
I have the flash drive and the right side usb connector from the Nomad plugged into the Siig hub. Flash drive is formatted gpart and into two partitions. One for music and other for dashcam.

Haven’t read thread from beginning and still haven’t tried out our Model 3 dashcam (that’s one reason I’m reading the thread), but from a few pages I’ve read people are saying they have partitioned the drive for dashcam and video, which the manual says not to do. Also wondering if people are using the Pause function to let it stop record/writing before removing. I know on our MS Blackvue we would get corrupted files if we pulled the card out before properly shutting down.
As for the file space it can write to, while Tesla doesn’t indicate about max drive capacity other than use the largest you can, our Blackvue dashcam could only write to a certain capacity. So maybe the same is true of our Model 3 dashcam. Would be nice if they put out more info and specs on it. Probably a work in progress if they are planning to add more cameras down the road.
Remember the car will power off when in Park mode after about 15 minutes even if you are sitting in the driver’s seat.
Here’s the Manual page with the info on using the dashcam in case people haven’t seen it. Manual updated 11/12/18.

My cam works for a few days and then fails. When I mount the flash drive in Windows it says it's corrupted. After fixing the partition, there's not much left, and the files that are left are sometimes corrupted. There are some commercial drive reconstruction utilities out there that will find the files and copy them. Do that rather than letting Windows fix the drive.
It's a total mess and Tesla needs to fix it.

I've had zero problems since switching from a garbage Microcenter branded USB drive (which was handy and unused at the time, but has awful performance) to a fast but not expensive Samsung USB drive (it was about $12 or so). Have you tried a faster and/or "higher end" drive? One of the theories is that corruption happens because the drive doesn't finish writing the last write before losing power when the car shuts down.

Some quick googling seems to indicate there's no way to do the dual partition format on a Chromebook (at least on stock Chrome OS), but if you want to just format it as FAT32 for just dashcam use (not two partitions for dashcam and music), then it looks pretty simple (assuming nothing has changed too much in 4 years ... ) : How To Format an SD Card or USB Drive on a Chromebook - OMG! Chrome!

I had a lockup starting Lunar Lander and had to reboot the MCU to get my display back When it came back I had the infamous Grey X. Unfortunately when locked up there is no way to pause recording and rebooting seems likely to corrupt the drive .
If you wish to create two partitions instead of just using the one already there, your Chromebook has to be in developer mode to get access to the command line tools. Enabling developer mode requires a powerwash/reset that deletes all locally stored downloads, so it's probably not worth the effort unless you can't borrow another computer to partition the device.
I'm experiencing the same or similar issue: An issue seems to be that the \TeslaCam directory has become "read-only," that I can't undo with DOS commands.!!! With a new datastick, problem went away. But browsing SanDisk seems to reveal a similar thread. If I put into the car a DataStick with the TeslaCam directory marked "Read only", I get a camera icon with an X. With the original (and now, new) data stick, (not read-only), the camera icon has a red dot and is (presumably) recording.
Research is needed into what "turns" the TeslaCam directory to Read Only, and why we can't undo the status.
Googling the DataStick Read-only directory issue show that other folks have that problem as well.

Can you create any directories / files in the top level of the USB stick? If not, it's possible the entire device has gone read only due to write wearout though that seems unlikely unless it was either a garbage device to begin with or an older USB drive you've had around for a while. A new device should last for months at least, even if it's a smaller storage or budget device.
If it is only the TeslaCam directory that is not working, have you tried reformatting the drive/partition ?
For me several newly formatted drives worked fine until drives were full, then quit recording. Exchanged several emails with Tesla support and issue seems to lie in software not overwriting oldest recordings so as to only store last few minutes of car’s operation.

Try a different usb drive. Some of them are just too cheap and cant handle the constant writing of the files from the camera.
Confused, wouldn't those videos just be part of TeslaCam's buffer (RecentClips) and not saved as MPEG-4s inside of the SavedClips folders? No reason to have Sentry Mode on if the car is parked inside the garage. Disable as you get out of the car when parking in the garage or disable from your app remotely. Sentry Mode would be the only way I can see video files automatically getting saved.
Tesla's manual says not to remove the USB flashdrive until you have paused the recording or the files will be corrupted.

This was many months before Sentry mode was a thing.
I was just pointing out that Dash cam mode records even when you're sitting in your car listening to music.
I just thought it was amusing. Now it is the buffer that it writes over so it's not like its taking up space.
