ext4 is a filesystem, and typically goes on a single partition of a
disk.  Normally your disk would have a partition table, and within that
you'd have a partition with an ext4 filesystem on it.  Do you know what
type of partition table is in use here?

My guess is that you're using the older DOS Master Boot Record partition
table (which I think gparted calls "msdos"); for disks over 2TB, you
need to use a GUID Partition Table ("gpt") instead.  You can see which
one is currently in use by going to View → Device Information in gparted
and looking at the "Partition table" entry in the table on the left-hand
side.
