The following program uses the Windows Scripting Host's FileSystemObject,
documented here:
http://msdn.microsoft.com/library/devprods/vs6/vbasic/vbenlr98/vaobjfilesystem...

require 'win32ole'
filesys = WIN32OLE.new("Scripting.FileSystemObject")
filesys.drives.each do |drive|
puts drive.driveletter
end

Cheers,
Dave

No.

This is highly operating system specific, and it's even hard to
define, especially when you include "network drives".

For Unix/Linux/MacOSX it would be rather easy, just run `mount` and parse the
output.

For Windows, you may just test every unit A: to Z:. You'll need to access the
Win32 API to look for volumes without an assigned mount point (unit letter),
such as SAN mounted volumes.

I don't know how to do it in Mac OS Classic, I never used those versions of
Mac OS.

On Windows systems, you can do:
require 'win32ole'
drives = []
file_system = WIN32OLE.new( 'Scripting.FileSystemObject' )
file_system.Drives.each { |drive| drives << drive.DriveLetter }
#drives now contains a list of existing drive letters.
puts drives

There are other useful properties on the 'drive' object, including
ShareName, which will tell you the network path, for remote volumes.
