try:

Listing 4.3 Enumerating Disk Drive Properties

1.      Set objFSO = CreateObject("Scripting.FileSystemObject")
2.      Set colDrives = objFSO.Drives
3.      For Each objDrive in colDrives
4.          Wscript.Echo "Available space: " & objDrive.AvailableSpace
5.          Wscript.Echo "Drive letter: " & objDrive.DriveLetter
6.          Wscript.Echo "Drive type: " & objDrive.DriveType
7.          Wscript.Echo "File system: " & objDrive.FileSystem
8.          Wscript.Echo "Is ready: " & objDrive.IsReady
9.          Wscript.Echo "Path: " & objDrive.Path
10.         Wscript.Echo "Root folder: " & objDrive.RootFolder
11.         Wscript.Echo "Serial number: " & objDrive.SerialNumber
12.         Wscript.Echo "Share name: " & objDrive.ShareName
13.         Wscript.Echo "Total size: " & objDrive.TotalSize
14.         Wscript.Echo "Volume name: " & objDrive.VolumeName
15.     Next

When the script in Listing 4.3 runs under CScript, information similar
to the following appears in the command window:

Available space: 10234975744
Drive letter: C
Drive type: 2
File system: NTFS
Free space: 10234975744
Is ready: True
Path: C:
Root folder: C:\
Serial number: 1343555846
Share name:
Total size: 20398661632
Volume name: Hard Drive

from: http://discuss.develop.com/archives/wa.exe?A2=ind0511d&L=dotnet-winforms&T=0&F=&S=&P=2611

That would be in ruby:

require 'win32ole'

file_system = WIN32OLE.new("Scripting.FileSystemObject")
drives = file_system.Drives
drives.each do |drive|
  puts "Available space: #{drive.AvailableSpace}"
  puts "Drive letter: #{drive.DriveLetter}"
  puts "Drive type: #{drive.DriveType}"
  puts "File system: #{drive.FileSystem}"
  puts "Is ready: #{drive.IsReady}"
  puts "Path: #{drive.Path}"
  puts "Root folder: #{drive.RootFolder}"
  puts "Serial number: #{drive.SerialNumber}"
  puts "Share name: #{drive.ShareName}"
  puts "Total size: #{drive.TotalSize}"
  puts "Volume name: #{drive.VolumeName}"
end

(beware, not tested code so errors can be there!)
