repartition after changing HD capacity jumper

Having some trouble nailing the keywords to google this, so I figured I'd
just ask...

I have a 40 GB disk that I jumpered to 32 GB since the BIOS wouldn't
recognize it, and have it partitioned as such. I've since upgraded the
BIOS, and now I can see the drive as 40 GB.

I can see the free space (in Linux cfdisk), so I'm wondering if I can just
make a partition there and start using it, or if those capacity jumpers
mess with the geometry, and might require me to repartition (and of course
repartitioning involves copying everything off, makeing new filesystems
and copying everything back).
 
Oh yes, this is a Seagate ST340014A. Just thinking different
manufacturers probably handle this hack differenly.

FRom what I remember, it just caps the number of sectors rather than
altering the whole geometry so the extra space just isn't accessed.
Make an extra partition and copy a load of stuff into it and see what
happens. Should be OK.

As an aside, both Windows 2000/XP and Linux could have used the whole
40GB even though the BIOS incorrectly reported the size prior to the
update.

Machine hung during POST until I flashed the BIOS, thanks for your
response.
