	static List<string> Files = new List<string>();
	static string Path;
	static void LookFor(string Path)
	{
		string[] Dirs = Directory.GetDirectories(Path);
		for(int i = 0; i < Dirs.Length; i++)
		{
			
		}
	}
	static void Main()
	{
		DriveInfo drive = DriveInfo.GetDrives();
		foreach(DriveInfo drives in drive)
		{
			if(drives.IsReady)
			{
		string[] Dirs = Directory.GetDirectories(drives.Name);
		for(int i = 0; i < Dirs.Length; i++)
		{
			Console.WriteLine("> {0}",Dirs[i].ToString());
			// LookFor();

I have updated your code to get all directories in recursive mode

C#

class App
{
    static List<string> Files = new List<string>();
    static string Path;
    static void LookFor(string Path)
    {
        string[] Dirs = Directory.GetDirectories(Path);
        if (Dirs.Length == 0)
            return;

        for (int i = 0; i < Dirs.Length; i++)
        {
            Console.WriteLine("> {0}\n", Dirs[i].ToString()); 
            // Code here for getting all the *.gif files 
            LookFor(Dirs[i].ToString());
        }
    }
    static void Main()
    {
        DriveInfo[] drive = DriveInfo.GetDrives();
        foreach (DriveInfo drives in drive)
        {
            if (drives.IsReady)
            {
                LookFor(drives.Name);

            }
        }
        Console.ReadKey();
    }
}

try this,

C#

static void Main()
    {
            foreach (string match in Search("C:\\", "*.gif"))
            {
                Console.WriteLine(match + "");
                //return;
            }
    }


  static IEnumerable<string> Search(string root, string searchPattern)
    {
        Queue<string> dirs = new Queue<string>();
        dirs.Enqueue(root);
        while (dirs.Count > 0)
        {
            string dir = dirs.Dequeue();
            // files             
            string[] paths = null;
            try
            {
                paths = Directory.GetFiles(dir, searchPattern);
            }
            catch
            {
            }
            // swallow              
            if (paths != null && paths.Length > 0)
            {
                foreach (string file in paths)
                {
                    yield return file;
                }
            }
            // sub-directories             
            paths = null;
            try
            {
                paths = Directory.GetDirectories(dir);
            }
            catch
            {
            }
            // swallow              
            if (paths != null && paths.Length > 0)
            {
                foreach (string subDir in paths)
                {
                    dirs.Enqueue(subDir);
                }
            }
        }
    }

like this you can give one by one drive name.
