12TB HDD 3.5 I/O error

[Peeteekadan]

I bought a new 12TB hdd 3.5 and it shows an I/O error. I want to use it in my desktop computer with windows 11 but I can't format it, I can't assign a drive letter to it, etc. Normal procedures (disk management, etc.) don't work. Please advise what I should do.
