This new disk, is it completely blank?  Is there nothing on it you want
to keep?  Here are the steps assuming it is blank.

- spin up either of the two linuxes

- run fdisk using "fdisk /dev/hdd" and hit p to see what partitions there
are already there

- using the d command if necessary delete the old partitions

- using the n command add a new partition to the disk, I'm guessing all
of it as one partition

- use the w command to write the changes to the new disk

- make a filesystem on the disk by typing something like

mke2fs -j /dev/hdd1

which will create a ext3 filesystem

- open your favourite text editor and add a line such as

/dev/hdd1	/mnt/newdisk	ext3	defaults	0	3

to your /etc/fstab

- create a mount point using 

mkdir /mnt/newdisk

- type mount -a to mount your new partition

- boot the other linux and change the fstab in the same way

All should now be well.

What do you mean by running?

I had a bit of a giggle too.
