Mark,

I use the following code to list Windows NT drives. Note, the list only
includes hard drives, not floppy or CD drives. You could assume the A drive
exists, but if you try to access it when it doesn't contain a disk you get a
Windows dialog message. The default assignment of the root directory in
ListDrives is designed to work with non-Windows systems.

 public static final String separator = File.separator;

 /**
  * Lists the drives on the system.
  * @return  an array of the drives on the system
  */
 public static final String[] listDrives() {
  Vector list = new Vector();
  for (char drive = 'C'; drive < 'Z'; drive++) {
   if (isDirectory(String.valueOf(drive) + ":")) {
    list.addElement(String.valueOf(drive) + ":");
   }
  }
  if (list.isEmpty()) {
   list.addElement(separator);
  }
  String drives[] = new String[list.size()];
  list.copyInto(drives);
  return drives;
 }

 /**
  * Checks if a string contains the name of a directory.
  * @param name  the string that contains the name
  * @return  true if the name is a directory; false otherwise
  */
 public static final boolean isDirectory(String name) {
  File file = new File(name + separator);
  return (file.isDirectory() &&
   file.exists() &&
   !name.equals(""));
 }
