WD Ses USB Drive Error

I am having trouble with my passport HDD.  I am getting the WD Ses USB not installed.  It is not recognizing it.  Can someone help?  It used to work before.  I have try downloading all updates and firmware and nothing seems to help


Have you installed a new OS on your computer?

You can download the SES Drivers from the following link. Just select the specific unit that you have according to the model number.


Also I see in another postthat you have, that you are saying that you are not able to copy or cut or delete files from HDD. Are you referring to the same unit as this post?
