missing /dev/hda2

[Debian Ghost <debian@ghost.ntelos.net>]

Hey Debianers,
I have a question about a partition of my hard drive that I can't seem to
locate. When I set this machine up, I set up a 10 gig drive to have
/dev/hda1 with 7 gigs and set the rest aside for another partition (can't
remember why I did this, but I did... I don't think I could get all 10
gigs in one partition) at any rate, I am quickly running out of space on
the 7 gig partition and I can't seem to find a way to mount my second
partition. Is there something I can run to see which device (if any) the
other 3 gigs are on, or is there something I can do to put that space on a
device (mount point) ?

Thanks!
