I was able to run it on Win XP without a problem. Incidently I was also able
to run your original program with minor modifications (see line 13 and
94 thru 97 of the attached ...).

But it failed when I uncommented lines 94 and 97  ** AND ** installed
the flash disk so that there were two logical drives.

I will  give that a try ...

At this point it does not seem like a win32ole issue since the following
snippet
works (at least on Win XP and ruby-1.8.1-rc13):
#---------------------------------------------
require 'win32ole'

host  = "localhost"
wmi   = WIN32OLE.connect("winmgmts://#{host}/root/cimv2")
disks = wmi.ExecQuery("Select * from Win32_LogicalDisk")
p disks

disks.each do |disk|
  next if disk.Size.nil?
  p disk.DeviceID, disk.Size, disk.FreeSpace
end
#---------------------------------------------
