It is one of the expected sets of values ....

sysinst must have a fubar for the total number of sectors being over 2^31.
It can't handle anything over 2^32 - but neither can the mbr or disklabel.

You might find that the mbr editor is ok.
So if you create a small (ie < 1TB !) partition first, install netbsd,
then use fdisk to increase the ptn size and then label the new ptn.
OTOH you could use a separate mbr partition for the big data ptn.
