Hi,
in the context of what you said above ... 
I have included the result of F13 live cd anaconda partitioning done on Paul
Cartwright's disk (the older thread with the same name dedicated to fixing 
it).
Can you explain the meaning of the last item (Free space)

   Logical   192425984*  192426569      0         586*Free Space           
None

being named "logical" and at the same being outside of extended
 partition's range

4 Primary   105076736*  192425983*     0    87349248*Extended (05)        
None

Should it be called "None" like the Unusable partition between 3 and 2 ?
Is that space mapped ("logical") or not ?
Will the installer (e.g. anaconda) know about it ?

Here are the outputs:

# cfdisk -Ps
