I am already using 2 WD My Book 8TB Model:WDBBGB0080HBK-EESN with P/N / N/S: WDBBGB0080HBK-NA.
I can’t understand what the abbreviations ‘‘P/N / N/S’’ really means.
I ordered a new 8TB Model:WDBBGB0080HBK-EESN and i found out that it is one with P/N / N/S: WDBBGB0080HBK-NB.

What is the difference between NA and NB?

I am living in Greece

P/N is an abbreviation for Part Number or Product Number

S/N is an abbreviation for Serial Number

(i haven’t heard of N/S … did you get it backwards ?)

EESN - E =EMEA (Europe, Middle East, Africa) E =External SN =Standard
PESN - P =APAC (Asia Pacific) E =External SN =Standard
NESN - N =PAN AMERICA E =External SN =Standard

I’m unsure, but most likely a Product Code, ID Code, Supplier Code or something like that.

I wouldn’t be concerned.

No, it isn’t backwards

Although i can’t find the Product Code ‘‘BGB’’ in this .pdf, everything is fine with this disk so far.

Thank for your answer
