Some untested code listed below to help you get started...

private static void SearchForFiles(string path, string pattern, List<string> SearchResults)
        {
            foreach (string file in Directory.GetFiles(path, pattern))
            {
                SearchResults.Add(file);
            }
            foreach (string dir in Directory.GetDirectories(path))
            {
                try
                {
                    SearchForFiles(dir, pattern, SearchResults);
                }
                catch (Exception ex)
                {
                    Console.WriteLine("Cannot access " + dir);
                }
            }
        }

        static void Main(string[] args)
        {
            List<string> SearchResults = new List<string>();
            SearchForFiles(@"C:\", "*.cpp", SearchResults);

            foreach (string s in SearchResults)
            {
                Console.WriteLine(s);
            }
        }

You'll need to use the DriveInfo class to help you check for all available drives

Search all the drives....

static void Main(string[] args)
        {
            string myString;
            List<string> SearchResults = new List<string>();
            DriveInfo[] allDrives = DriveInfo.GetDrives();

            foreach (DriveInfo d in allDrives)
            {
                if (d.IsReady == true)
                {
                    myString = String.Format(" {0}", d.Name);
                    Console.WriteLine("Checking drive {0}", d.Name);
                    SearchForFiles(myString, "*.log", SearchResults);
                 
                }
            }
            foreach (string s in SearchResults)
            {
                Console.WriteLine(s);
            }
        }

foreach (string file in Directory.GetFiles(path, pattern)) {
    SearchResults.Add(file);
}

I'd have done this a little different by getting rid of the foreach:

SearchResults.AddRange(Directory.GetFiles(path, pattern));

What do you mean by an "external hard disk"?
