Quote "As Ray mentioned, if your new drive is unpartitioned and/or 
unformatted;
            I assume that you can use 'fdisk' to partition and mkfs.????
            to create a filesystem on it. "

To create a partion, run fdisk and partion the correct device.  If you 
wish to format the drive with a file system, you can use:

          mke2fs /dev/hdXX (sdXX for scsi) for an ext2 partition
          mke2fs -j /dev/hdXX for ext3 partition
          mkresierfs /dev/hdXX for a reiser3 partion

I personally use an ext2 on my boot partion, and a reiser 3 for 
everything else linux.

One more thing, the partitions must have a file system installed in 
order for you to mount them.
