Does EasyStore disrupt synching among MAC products?

I am unable to sync my iPhone and ICloud information, such as notes and calendar data, to my MAC software 10.14.6. I spoke to an Applecare advisor, who believes my WD Security Software for the WD Easytstore external hard drive may be preventing me from synching. If I uninstall the WD software on my MAC to try restore synching, will this action remove important data or password information from my external hard drive?
