hdd in aliexpress used modified

I bought a 2.5″ HDD on Aliexpress and it is inside an enclosure case. I know it is used, but most of the 2.5″ HDDs sold on Aliexpress are used but show 2 hours of use and good health on crystaldiskinfo. What do they do?

Do these Aliexpress sellers also modify, remove or disable important functions within the firmware such as power management or other features, or do they use firmware from another HDD model?

Do they change or disable some system settings (such as power management) within the firmware and does this affect the parking system?
