    Hello,

    Whenever I attempt to format the SD card with guiformat, I get the error below:

    Error:
    Failed to open device
    GetLastError()=32
    The process cannot access the file because it is being used by another process.

    SD card: SanDisk 128GB Ultra SDXC UHS-I (not MicroSD)

    I've already tried a few things but still get the same error:
    1. Format at 64KB
    2. Format at 32KB
    3. Start in Safemode and Format
    4. Tested in another computer with an integrated SD card reader
    5. Tested with a SD to USB adapter (it's a no name brand but should work as I've used it in the past).
    Some side notes:
    1. The card is readable and I can write to it.
    2. I tested using Windows to format and it was able to format without issues (in exFAT)
    Currently in process of using H2testw to check authenticity of the card. Will post results once complete.

    Update: H2testw completed and looks like the card is real.

    Any help is appreciated! Thanks in advance!

    Open disk management (Windows), check if it's showing there. If it is, format it through that.

    Yes, it does show up there and I have formatted using that but it can't format in FAT32, which is why I was attempting to use guiformat to do it for me.

    When I build recalbox for Pi3, I have similar issue and this always fixes it for me.

    Authenticity was confirmed or?

    I've already formatted using Windows but it's in exFAT now, but FAT32 is needed.

    Just to see if it's fake or not and if it is fake, possible that it may be causing the issue even though it seems unrelated.

    I always get that error. What to do is to go to This PC > Right-Click on SD card drive L:\ > Format... , normally re-format as exFAT or NTFS so it kills any random processes in it, run that program again then format to FAT32.

    Hmm I think I already tried that but I'll keep that in mind for the future if I need to do it again. However, I was able to format into FAT32 using another program called "MiniTool".

    In case anyone has the same issue, try this program: http://www.minitool.com/

    Thanks all for the responses!

    use h2testw to see if it's fake. it will write over the entire card, then verify the data. that will tell u if there's a problem.

    I already ran h2testw. I updated my first post with my results. Looks like the card is real.

    I just read the post u made about whether it was real or fake. sometimes u have to format the card in windows, then fat32gui. I've had this problem before, and that's what fixed it. it would say the device was being used by another program (error) when it wasn't. fat32gui would say that anyway. windows formatted it no problem.

    I have that problem all the time. Make sure ALL your Windows explorers windows are closed and try it again. That fixes it for me.

    Drag the app to the desktop and close everything that's open. That fixed my error.
