    External Hard Drive wont boot


    Hi, I have a WD 2TB HDD1021 external drive and when I connect to my Windows 10 PC I get what looks like the partition in the drive ( 31 GB)which shows the following files;
    Bootmgr.efi
    bootmgr
    setup.exe
    autorun.inf
    boot
    efi
    sources
    support
    All my back-up files are not showing


    I went in to Disk Management and found the partition where the my files were backed up, was showing as unallocated. I allocated a drive letter, but now I'm getting the following message;
    The Volume does not contain a recognised file system. Please make sure drivers are loaded and the volume is not corrupted.
    I'm being prompted to format the Hard drive which I know will delete my back-ups. Can anyone please help.

    I'm running Windows 10, version 1909

    To assign a letter you must have it formatted. Don't do anything.
    The files you mentioned are from a installation drive. Tell us the story of this installation files. How and when they were transfer to the drive.
    - Did the disk had these files when you were able to access your data?
    - Did you use any program (like Rufus) to make it a boot able drive?

    Open Disk Manager, expand the window and the columns so we car read them and with the snipping tool take a snapshot of the whole window. Post the image here as an attachment.

    Hi, thanks for the very prompt reply.
    I have no idea how the files were added, however when I looked at the "exe" file, it is a Windows Installer which was added on the 7th April.
    I use this drive very infrequently and I don't know when the files were added.
    I have never used Rufus to make a bootable disk.
    I have attached my disk Management file for your perusal

    For what I can see, the HDD was used to create a Windows installation drive. To be able to boot as UEFI, the disk was partitioned (32G) and formatted as Fat32. The remaining partition remained unallocated.
    Open /sources. Do you have a install.wim or install.esd ?

    The F: drive 32 GB Fat32 partition is named ESD-USB. This is the standard name used by the Media Creation Tool when it makes USB install media. It is almost certain that this USB extenal HDD was chosen by mistake as the destination USB when running the MCT.

    I also suspect the same thing, that is why I asked to OP to confirm if he has a install.esd file.
    I think the chances to retrieve the data is very low.

    The partition table and the first 3 to 4GB will have been overwritten by the MCT (8GB if the MCT was making media for both x86 and x64). Data there would be lost forever, but the rest of the drive would have remained untouched and may be recoverable. Or at least it may be as long as @Agh55 hasn't made any further writes to the drive.

    @jumanji knows a thing or two about data recovery and may be able to help. The important thing is for nothing further to be done to this drive until advice is received.

    The Partition needs to be recovered - as it is now in RAW format
