Need Smartware SW for My Passport Essential - HDD Crashed!

My iMac hdd crashed so I had to rebuild. My iMac is running High Sierra, 10.13.6. Trying to find WD Smartware software for my WD MyPassport Essential 2.0 TB drive. I tried some 3rd software but none work. Too much data on this drive to forget about it.

Any ideas on how I can restore all files from this drive? Where can I find the WD Smartware for Mac? PLEASE HELP!!!
