I did a hard format, but I can only use 2T, so why is that?

A. 1

It's not just 2T available, but it probably remains inactive.
If you go into Disk Management, you can also activate the rest of it and write.

A. 2

I think you did it in MBR when you did the hard format.
The MBR format allows up to 2TB of recognition.
So like 3TB, if it's over 2TB, it's divided into two.
You can divide it into two
Or you can format it using GPT method.
