Windows 7 USB/DVD Download Tool error: We were unable to copy your files. Please check your USB device and the selected ISO file and try again

I have written about how to make a bootable USB installer for Windows 7 and 8 by using the     Windows 7 USB/DVD Download Tool. Sometimes if your USB stick has something in its MBR you might get the error

We were unable to copy your files. Please check your USB device and the selected ISO file and try again.

I found the solution to that problem in this post.

You have to start command prompt as an Administrator (On Windows 7 that means right clicking the cmd and selecting Run as Administrator) and use the diskpart utility.

  1. Start command prompt as Administrator and type  diskpart 
  2. type  list disk
  3. type select disk  and number of your USB disk ( like select disk 1 )
  4. type  clean
  5. type  create partition primary
  6. type  select partition 1
  7. type  active
  8. type  format quick fs=fat32
  9. type  assign
  10. type exit  to exit the diskpart utility
  11. type exit  to close command prompt

diskpart

      You can try to disable your antivirus, I have found people on some site saying that that caused problems for them also.

      You can also try to format your drive as fat32 without using the quick option. Do you get any error when you try to format your drive?

    the solution is very easy ,restart clic on F8
    choose windows sans echec or windows safe mode
    then relance the aplication and it will work

    I did this, and still didn’t work for me. I found out my Avira antivirus was meddling with the USB while the download tool was copying files on to it. After I turned it off, it worked. So turn of any antivirus when proceeding with the copy. I think its because the download tool writes on the boot sector or some place on the drive that is also a behavior of viruses.

    Worked, thank you. My usb kept being formatted to NTFS instead of FAT32 using the utility and using diskpart fixed it.
