Advanced format 4Kn sector device identification is incorrect

[nasbdh9]

This is a 4Kn sector device but the capacity identification is not correct, maybe this is because of windows api problem?

Is it possible to record all Smart? Currently, recording only the current value may be inaccurate for judging certain hard drives.

long time ago, I realized that this may be a Windows API problem. Under the native 4Kn format hard drive, the correct capacity should be eight times the displayed value

I am experiencing this same issue after changing from 512e to 4kn

I can't give you full info, as I have the drives raided, but I have provided what I can below :

However, these are 14TB WD Drives WD140EMFZ which I have reformatted from 512e to 4kn using the WD Hugo tool. I also did the same with the 12TB WD Gold drives I have WD121KRYZ which has the same issue in Diskinfo.
