Assuming you're on a Windows machine using CF8 these are two methods
that I am aware of:

1) Using .Net version 2 or greater - see
http://www.forta.com/blog/index.cfm/2007/5/30/GetDriveInfo-UDF-Powered-By-NET

2) Using Java -

<cfobject type="java" action="create" class="java.io.File"
name="objFile">
<cfobject type="java" action="create"
class="javax.swing.filechooser.FileSystemView" name="objFSVTemp">

<cfset arrRoots = objFile.listRoots()>
<cfset iArrayLen = ArrayLen(arrRoots)>

<cfset objFSV = objFSVTemp.getFileSystemView()>

<cfloop from="1" to="#iArrayLen#" index="i">
    <cfoutput>
        <strong>Drive: #arrRoots[i]#</strong><br />
        Available Space: #arrRoots[i].getFreeSpace()#<br />
        Total Space: #arrRoots[i].getTotalSpace()#<br />
        <br />
    </cfoutput>
</cfloop>

Hope that helps.

Cheers
