While using the Windows 7 USB/DVD Download Tool to create a bootable USB drive to use for reinstalling/repairing Windows, I ran into the following error message:
Windows 7 USB/DVD Download Tool error: We were unable to copy your files. Please check your USB device and the selected ISO and try again.
I found the following link to a discussion about the issue:
Then enter the following commands to identify and format the USB drive in question:
Microsoft DiskPart version 6.2.9200 Copyright (C) 1999-2012 Microsoft Corporation.

After completing these steps to format the target USB drive, I was able to use the Windows 7 USB/DVD Download Tool to successfully create a bootable USB drive. Also note that despite the name, this tool also works to create bootable Windows 8 USB drives.
