I have these two drives

WD60EZRZ-00GZ5B1 6001.1



WD60EZAZ-00ZGGHBO 6001.1


And need to know if these are PMR or SMR. Filled out an online email form and received no answer. Called tech support, the 1st agent did not know what PMR or SMR are. And after some coaxing, said that they are both PMR, but that doesn’t make sense because of the weight of the drives and their buffer sizes.

And a supervisor said they can’t disseminate the information I’m asking for. So… Talk about incompetence and a lethargic response - like they didn’t even give a hoot. Can’t even answer a simple question on the fundamental technology in the product.

AND GET THIS! The second “technician” said SMR stands for Standard Metabolic Rate! Funny and sad at the same time.

A third time I called in I was told that this information is not available and and cannot be disseminated to customers.
