This document provides instructions on how to use a tool to write files to a USB drive. It explains that selecting a source file, target device, and clicking write is all that is needed. If devices are plugged in or out, the refresh button will update the target list. It also describes that Windows may incorrectly see the USB drive as one partition after writing, and users need to delete the partition and recreate it to properly format the drive. Potential error messages are also listed and described.

How To Use
----------
This tool is quite easy to use, you juste have to select an input file, a target
device and then click on the Write button. You can use the Browse button to
select an input file rather than typing its path by hand.
If you have plugged or unplugged an USB drive after having started the tool,
just click on the Refresh button to update the target list.
Since I have used your tool, Windows does not allow me to format my USB drive at
its initial storage size
--------------------------------------------------------------------------------
-------------------------
That's right, but that's a Windows issue. Windows implicitly considers that an
USB drive has only one partition, and the actual partition pour your USB drive
has the size of the image file you have just written to it. You have to delete
the partition and create another one.
From the Start Menu, right click on Computer and click on Manage, a window named
Computer Management opens. Click on Disk Management, you will now see all disks
connected to your computer and their partitions. Right click on the partition of
your USB drive, and click on Delete volume. All space on your USB drive is now
unallocated. Right click on the unallocated space and click on Create Simple
Volume, a wizard opens. Follow instructions to format your USB drive (just press
Next at each screen if unsure, that will be OK).
Pretty annoying behavior, but since it's a Windows issue, I cannot fix that.
Report the bug to Microsoft or switch to a more clever operating system (OSX is
fine, GNU/Linux is better).
