|Are both computers able to ping each other?|
First, establish an active network connection.
Did you create a share on the 1 TB drive and a user/group and grant appropriate permissions to said share?
If not, you're going to have to. You can't connect to what isn't there right.
NOTE to OP's that don't want to come back and check for a response within a short period of time. If you wait too long, we'll assume you don't deem it important and will not likely respond when you do condescend to come back and check. So be aware, this is something we do out of the kindness of our hearts. We don't owe you anything and are not obligated to help you. If you want our help, I suggest you return quicker than "3 or 4 days"
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
