    What error message did you get when you tried the "create partition primary align=1024" command?

    Windows 7 doesn’t recognize 2 drive letters for multi-partitioned usb drives. I think that didn’t become available until windows 10. I tried doing this on a windows 7 computer and it errors trying to create a second primary partition. I even tried using a third party app. It’s a no go unless you’re on windows 10 (no go for me anyway)

    Thanks for the update. I wonder if anyone has tried Windows 8 or 8.1?

    No kidding.

    I still see the Mac Vs Windows wars raging on the internet and the usual charge that Mac users are dumb toaster users. Joe reminded me that the overwhelming majority of Windows users are frustrated toaster users until an expert happens along to hold their hands while crossing the street.

    @SomeJoe7777 - Why didn't you do the format in DISKPART as well?

    Code:
    select partition 1
    format fs=fat32 label="Recording" quick

    Thank you for the help. I used the procedure on my SanDisk 64GB Wireless Stick. The dashcam works and I do not even have AP. But I have the hardware. (Ordered the car w/o Autopilot option)

    I don't remember exactly but I am on Win7. :cool: Maybe I can just start all over and just make it all one big partition?

    That is what I have read...though this process was getting around that some way. :confused:

    I know, right? Isn't it ironic that the Mac manages Microsoft's legacy file system better than Microsoft...?

    I wanted to make sure that the default method of formatting was used, just in case DISKPART does something different. It probably doesn't, but I don't know that for sure.

    Yes, you can make it one partition, although I would try a small partition -- use size=16384 or size=32768. We don't know what bugs are in the Tesla's FAT32 file system driver, so a smaller partition might work-around any potential issues. For this first version of the dashcam functionality, we don't need a super large partition anyway.

    The other method would be to try and partition and format it using a GParted live CD. That's about the only tool that I might trust to format it correctly.

    MS has deprecated that software in favor of ntfs. That is the MS way: Their newer stuff is "better" (and you should upgrade) because the old stuff does not work very well anymore ... A person living in the MS universe understands relativity.

    Indeed. Or a *nix. Really, anything these days except Windows

    As others say, that is a great piece of work. I did almost the same thing, however I did not find the need for a 3rd party formatter. I was able to do everything by using the Windows 10 Disk Management program and used it to create the Fat32 partitions. So far after a week, it works fine. Again, nice job and clearly you took lots of time to do this.

    Amazing and detailed write up.
    I have to ask a dumb question: is it not possible to use a USB splitter so we can use one USB port for both music and dash-cam?

    Almost. It was deprecated in favor of exfat. The reasons behind this are somewhat technical, but essentially FAT (including exFAT) are for removable devices and NTFS is for fixed storage. Obviously you can use NTFS with removable and you can use FAT for fixed storage.

    From a non-user perspective I like FAT because you can trivially parse the file system by hand. Even decoding the timestamps isn't that bad. NTFS... well, its an over designed object oriented file system that you need tools to do much with. But it is really cool and does things you cannot do with a FAT file system.

    Yes, you can do that. There are several small 2-port USB hubs on the market that will let you use 2 flash drives at the same time. I just wanted a cleaner solution.
