No.

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

Eivind.

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.
