No Sectors left of 120GB Drive

Hello all!

I was about to make a new partition on my hard drive when fdisk reported:

Command (m for help): n
Command action
   l   logical (5 or over)
   p   primary partition (1-4)
l
No free sectors available

Now I know full well there are more sectors available as I am using less
than half of the drive!

Disk /dev/hda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1          13      104391   83  Linux

As you can see I should have 16065 cylinders but  cannot access them.  I
am as sure as I can be that once upon a time (probably when I made the
last 3 partitions for my Rawhide distro) that the end block for the
extended partition (#2) was a greater number, and in fact when running
Anaconda trying to install FC6Pre the partitioning program shows a LOT
of free space on the drive so I figure that either I can't make new
partitions because 8 is the limit (I don't know what the actual limit is
 but I discount this as a possibility as fdisk seems to be showing me
that /dev/hda10 is butted up against the end of the drive) or something
nasty has re-written my MBR to tell fdisk there's no more room.

So, fellows (and ladies!) My questions are:
	Is there a definite maximum number of partitions allowed on a drive,
and have I reached it?

	how do I recalculate drive parameters and fix the MBR (if that is the
problem.

I am resisting the urge to wipe and re-install as this represents 3
linux distros and it would likely take a month to fully recover them!
