The following writes from TargetSource down, all duplicates found
in SourceRange down.
Just set your Source and Target ranges in Definitions.
=========================================
Sub WriteDuplicates()
Dim SourceRange As Range, TargetRange As Range
Dim i, j As Long, TestColl As New Collection

Application.Calculation = xlCalculationManual
Application.ScreenUpdating = False

' Definitions
' ---------------------------------
Set SourceRange = [Sheet10!AA189]
Set TargetRange = [Sheet10!AB189]
' ---------------------------------
If Not IsEmpty(SourceRange(2, 1)) Then
Set SourceRange = SourceRange.Resize _
(SourceRange.End(xlDown).Row - SourceRange.Row + 1)
End If
For Each i In SourceRange
On Error GoTo WriteDuplicate
TestColl.Add i, CStr(i)
Continue:
Next

Exit_Sub:
Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True
Exit Sub

WriteDuplicate:
j = j + 1
TargetRange(j, 1) = i
Resume Continue

End Sub
==========================
Ciao

Viktor,

Here's a technique that I use.

Assume your list is in column A starting with a header in cell A1, data
in cel A2, and as you said, runs over a thousand rows.

In cell B11 type this formula

=VLOOKUP(A11,A$1:A10,1,FALSE)

Copy the formula up and down column B to match your data.

A #N/A will appear next to the first instance of each data value. A
repeat of the data value will appear next to the 2nd and subsequent
occurances.
