Tesla Dashcam issues

edited November -1 in Model S

I just bought a 64gb usb 3.0 drive from sandisk and this is what the footage looks like, what am i doing wrong i bought a 3.0 to make sure it would be fast enough and i know the tesla is only usb 2 but that doesnt really matter. Please Help, other drives have the same issue

    @Roel - First I'd try a reboot - might fix it, but I suspect not.

    While USB 3.0 is capable of being faster than a 2.0 drive, it doesn't' mean it is fast enough. The drive may not be fast enough to deal with 3 video streams. I addition, some drives are rated high speed only for bursts, but not continuous recording. Then there are counterfeit drives (with brand names) that are really bad. Here's a lot more on how to validate a drive and more on picking a suitable drive:

    At the end is more troubleshooting suggestions.

    The weird thing is is that it should be fast enough it's a real SanDisk ultra flair and it should reach write speeds of up to 60mbs

    Or something like that

    Some people have tried USB drives that consist of a USB adapter and SD card, which they claim can handle higher write speeds and more extreme temperatures than regular USB drives. I didn't notice any mention of that option in TeslaTap's article, and I can't vouch for the quality.

    I found one example on YouTube here: This configuration also has a lightning connector on the USB adapter so the video can be viewed on an iOS device, which is something I would like.

    Right repeater on S had highly pixilated frames and sometimes files of size 0kb. They replaced it.

    ‘17 S75. (Uncorked [E]AP FSD AP2.5 MCU1 Bio 16.1)
    ‘17 X75D (Uncorked [E]AP FSD AP2.5 MCU2 Bio 12.1.2)
    Grin on!

    @TeslaTap - Have you hear of, and what do you think of the pre-formatted Vteq Card Reader?

    @Hart - I haven't tried it myself, but I don't see any red flags. Should work fine, although I'm not familiar the the Vteq brand.

    @TeslaTap - Seems to work for me, but the fit for the S is awkward at best. They made it for the 3 I guess. Just was curious if you knew of any rad flags.

    So, I have installed a real SSD via a good USB connector. This should provide the speed, space, and reliability needed for all of the video streams being written.

    The SSD is a Samsung 840 SATA drive. I put that into a very low cost but high quality SATA-to-USB 3 (and USB 2) enclosure. (This is where I get them: - it can sustain over 420MB/second writing with the Samsung SATA drive when using USB 3. On USB 2 it is limited by the USB 2 interface)

    Anyway, this works relatively well but I still get occasional bad video files. I think that it depends on what else is going on.

    My Model S is older - from 2017 - so it has the older MCU1 and an early AP2.5 hardware board. I think the 3 camera streams are pushing the limits of the system as it stands right now. Maybe the HW 3 update will help with the dedicated hardware for generating the encoded videos.

    PS - I think it also helps to turn off live traffic in the maps in order to make things more stable.

    After the latest update my dashcam stopped working, the error says that I need to use a faster speed usb drive.
    I am using a SanDisk Ultra CZ48 128GB USB 3.0 that can go as 100MB/s transfer speed.
    This drive works flawlessly before the update. I reformat the drive a couple of times, but still same issue.
    Tesla support told me that the update has nothing to do with my drive, they suggested to replace it because it might had been corrupted.
    I bought another usb drive 64GB USB 3.0 50MB/s capable speed, It works for a day, then it also stopped working.
    Tesla could not give any solution to this issue until this time.

    I'm now suggesting switching to a micro SD card and small adapter. This is not much larger than a flash drive, and you can buy a micro SD card that is designed for dashcams - high endurance and wide temp range. So far these seem to work flawlessly. Here's my list and more details:

    As a bonus, you can also plug the adapter directly into your phone or tablet and view video. You do have the pick the right adapter for your phone (micro USB, USB C, or lightning).
