That's true.
Hard drive allocation tables haven't changed since the stone age.
There are exactly four entries in a partition table. Each can point to
either a primary or extended partition. A primary partition has a file
system which holds data files. You have four of those.
An Extended partition starts off with...another partition table, which
has four entries. Again, each of those can point to a primary or
extended partition. So you can have a chain of extended partitions,
which will allow many data partitions.
But your first partition table is full. The only way to do what you
want to do would be to 1) do a full backup on the fourth partition, 2)
delete the fourth partition, 3) create an extended partition, then 4)
create more data partitions there.
It would be simpler just to expand the last partition to include that
174GB.
There's a nice discussion of partitioning here:
