Power Adaptor for old external hard drive WD800B05RNN

I have an old but still fully functional WD800B05RNN Western Digital external hard drive. The 4-pin power adaptor has lost two of its pins, but strangely enough still works fine. But I would love to have a replacement adaptor, and it has been discontinued by WD. Does anyone have a used one they no longer use and are willing to contribute or sell? [Deleted]

You are correct. It does not show on the list bellow.

You could try searching on Ebay.
