Hello everybody!
I ordered for aliexpress WD 4TB. On label the HDD, the model code is WDBU6Y0040BBK-EA. But when I registered the HDD by the serial number on the VD website, they wrote that the model of my HDD is WDBU6Y0040BBK-CESN. Who knows what the EA and CESN indices mean?
this pdf has a breakdown of the product codes
