Hi, Jim.
Should be no problem at all.
Shut down and power off your computer. Physically plug in the new drive and
make sure your BIOS recognizes it on reboot. (This varies by computer, so
I'll leave the details for later if you have a problem.) Then reboot into
Vista.
In Vista, use Disk Management (diskmgmt.msc) to create one or more
partitions on your new HD, format it/them, and assign the drive letter(s)
you choose. As you probably know, "drive" letters are not assigned to the
physical drives, but to the individual volumes (partitions and logical
drives) on each physical drive. So it's a good idea to also right-click on
the volume (in the Graphical View) and use Properties to give each volume a
name. Then, even if a later change in your HD configuration causes the
"drive" letters to change, you will still be able to recognize the volume by
its name.
You will not need to re-activate Vista for this.
