I believe this a manager for my Western Digital External Drive

Part of Western Digital's SmartWare for their external USB drives. It's /way/ too "chatty" for my liking, though. All it should be doing is checking for software/driver updates, but it doesn't need to phone home every few seconds just to do that.
It can consume upto 50% of an I-7 quad core processor. I'm having an issue with it. About to uninstall the whole thing. I recommend that you avoid this CPU hog.

Best practices for resolving WDDMService issues

A clean and tidy computer is the key requirement for avoiding problems with WDDMService. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
