Able to Unlock Yet Access Denied

As I said on my other post, we change the motherboard and processor of my husband’s pc. 

The issue now is about his My Passport Essential. He was able to unlock the drive but a message shows access denied. What to do?:crying_cat_face:


Try reinstalling the drivers for the unit…


Driver for the WD Passport? Can you pls post here the link where I can find the said driver. Sorry not so familiar with tech thing. Thanks 

I checked it again and it says: 

Update Driver Software-WD My Passport 070A  USB Device 

The best driver software for your device is already installed 

Windows has determined the driver software for your device is up to date 

When I tried to open the WD Passport it says Location is not available (L:\is not accessible) Access is denied 

Question: How do we find out the original location of the WD Passport when it was installed in the old motherboard?
