USB to eSATA adapter?

I have a WD Mybook external HD with a mini USB connection.  I would like to plug it into my Xfinity DVR through the eSATA port.  Question  Is there an adapter that converts the standard USB connection to eSATA?

Hi,

Unfortunately Western Digital does not have such an adapter and we cannot recommend using one either. If you want to use a drive on a DVR I recommend you get a “MY Book  AV” DVR Expander.
