3 years warranty

Hi. I just bought a portable WD My Passport 1TB. I have successfully registered the product but the warranty period is shown 2 years. I know that all WD My Passports portable drives bought now have 3 years warranty even if on the product case is written 2 years.
Please, tell me how can I benefit of the 3 years warranty? Thanks a lot.

Hello,

Can you please share the drive’s model number?

Hi. The model number is WDBYNN0010BBK-WESN.
