I can appreciate this, however, did you do this prior to installing and
using the hard drive? I don't
want to move or add swap partititions if "good" data is already present
there. How can I check for this?

bigweb servers have 4 2gig swap partitions. And that is with 2 – 4 gigs
of ram.
What does the box do?
If you are going to do a lot of swapping then you might want to add
pri=0 to the fstab.
Here is what my fstab looks like.
/dev/sda3 swap swap defaults,pri=0 0 0
/dev/sdb2 swap swap defaults,pri=0 0 0
/dev/sda2 swap swap defaults,pri=0 0 0
/dev/sdb3 swap swap defaults,pri=0 0 0
With pri=0 swap will be used on all partition at the same time. When you
do not set pri=0 one swap partition will fill up first then the next and
so on.
But that would be over kill for most people. Only reason I have my swap
setup that way is due to the way apache locks memory when you have 2000+
apache processes running.
