Just a quirk of whatever is displaying the partitions.

Nope, the limit is imposed by the number of entrys available in the partition table.
So you can certainly have 4 real partitions and some free space as well if you want.

fdisk doesnt.

The old dos norton's diskedit will, and allows you to edit it too.

Plenty should turn up using google and "partition table"

Jim,

If you are running Windows XP you can find DskProbe.exe on the setup
CD in the Support\Tools directory. DiskProbe will allow you to view
the hard disk at the sector level and understands the layout of the
partition table and boot records to allow viewing their individual
fields.

Use a disk editor to read (IIRC) the second 512-byte sector of the
disk. It's been a long time since I did it "by hand", but with the
assistance of one of the early chapters of the "Pink Shirt Book", the
partition table in a PC-ocmpatible hard drive is perfectly
comprehensible. Don't ask me what the format of the data is - that's
what reference books are for and I've loaned my Pink Shirt to
PeetThePervert - but it's perfectly comprehensible.
