Where did this filesystem come from? It's a v4 filesystem, so
unless you specifically made it that way it must be a pretty old
filesystem.

What is the drive hardware and how is it connected to the machine?
e.g. perhaps it is an an external drive connected through a USB-SATA
bridge and the bridge hardware might be advertising the drive as a
4kB sector drive incorrectly?

Cheers,

Dave.
