  1. Why did my USB drive become FAT32 out of thin air?


    This post is also a bug report.

    I have x86 bit windows 10 pro, latest version.

    No viruses.


    I was running a git bash command when I got an error in the command. I had just browsed around the drive normally. The error said "Unknown file system - is the disk drive corrupted?"


    I was confused, so I browsed around the drive. The folder took too long to load. Then, the error came. Unknown file system. So I clicked the "Format" button, to see that it would erase the entire drive. When it showed options you could use to format it, it showed the default was FAT32! I was confused. I knew that having a FAT32 drive on NTFS would show some .sys files. I was more wondering how NTFS could INSTANTLY become FAT32.


    I updated all drivers (it was something like NTCS family controller)

    I then updated windows as I rebooted with the new driver, to get it working.

    Now, when I boot up windows, I always get a black background, with some working GUIs, like personalized settings, and a startup program that is simply a bar. Then, personalized settings crashes and file explorer. I know this is because of a failed script, and this has happened once before. I will give an update as to when this stops.


    How did this happen?

    Are there any fixes?


    I am currently trying my last 2 options of third party programs that will keep your files while formatting.

    :)

  4. Why did my USB drive become FAT32 out of thin air?

    Unable to open files on FAT32 Drives (Do not have permission)

    Hi Chad,

    Thank you for posting in Microsoft community.

    Sorry for the inconvenience caused to you. I’ll certainly help you with this.

    I would like to let you know that Windows 10 doesn't support FAT32 formatted drives. I suggest you to take the back up of the files and format the drive in NTFS format. To do so, follow these steps:


    • Connect the USB drive to the computer and right click on it.

    • Select format and set the file system to
      NTFS(default).

    • Select click on Start to format the USB drive.

    • Now, transfer the files to the drive and check if you are able to open the files.

    Hope this will help you. Keep us posted with the status of the issue to assist you further.

    Thank you.
