Back-up software needed for my Legacy WD1200 external drive

I have a WD1200B015 external drive that is about 4 years old but used very little. After getting a new computer (same XP OS) I cannot locate my original Retrospect back-up software. Any idea where I can download it from? I tried to Download WD Anywher back-up but WD site would not allow download (I assume because of the age of the drive).

WD does not work with retrospect anymore.

You might need to get another backup software Windows backup is free and also is included with the Windows OS.
