• I don't know. However WD has published an extensive list of their drives which identifies what type they are, CMR, SMR, or PMR. You will have to open up the case to identify the specific drive which voids the warranty. I have 5 of these drives and each one reports a different architecture using Speecy diagnostics. Speecy doesn't read the actual magnetics schema. Sorry.
