so unknown space 759 GB

It's not lost. It's* used for housekeeping,

759 GB only for housekeeping?

and is absolutely necessary.

But not in this size.

Formatting sets aside a fixed space for this, which varies with the
file-system.

Also, it's 182 MB, not 191GB

GB here. Not MB.

As mentioned above, I transferred all the contents
over to another drive, then formatted the problem
drive, re-assigned the original drive letter,
transferred back all the old contents, and so got
back all the space.

So I guess we, meaning you and all of us, will never know what the issue
was. I'd have been curious to see what was going on.

The rest is mystery. I tested that drive with
Seagate tools & HD Tune and found no faults.
