I have the same problem with MS products on a 9.1 gb drive.  Check, 
BTW, your cylinder/gb count.  I'm guessing your 1024 mark is right at 
7.82 gb rather than 8 gb.

I have been able to use earlier versions of PM, say 3.05, to create 
extended that encompasses the entire drive, but it won't touch the space 
beyone 1024, nor will anything else -- except Disk Administrator in NT, 
which will format a useable FAT16 logical there.
