arrived is a little Windows tool that will invoke a command whenever a new USB device, or more specifically drive, arrives in the system. That is, whenever you plug in or remove a USB drive such as a USB key or an external hard drive. So now you also know where the name came from.
No installation required. Download the binaries (32 and 64bit) from my website or Bitbucket. Use an archiver to unpack the archive, I recommend 7-Zip, and then place the .exe files into a folder listed in your PATH environment variable.
In order to build the tool yourself, you'll either need the Windows 2003 Server DDK or Visual Studio. If you use the DDK, you can simply rely on the relbuild.cmd script, but you may have to set the WNETBASE environment variable to a sensible value (e.g. WNETBASE=C:\WINDDK\3790.1830) to match the path to the installed DDK.
If you prefer to use Visual Studio, a solution/project for Visual Studio 2005 is included and you can generate any of the other supported projects yourself using the premake4 that comes with the WinDirStat source code. Use a tool such as sigcheck to verify the code signature on it, though.
The way you generate the projects is by calling premake4 one of the following ways:
premake4 vs2005 premake4 vs2008 premake4 vs2010 premake4 vs2012 premake4 vs2013
The earlier Visual Studio versions may work, but no guarantees.
The program should run on Windows 2000 and later. Itanium CPUs are not supported, but feel free to build that yourself, if needed.
arrived <command> [-only=drive_type,...]
The default if --only is not explicitly given is removable. Otherwise the following drive types should be valid:
