Norton Security Suite no longer shows my external harddrive in the backup locations list

Hello,

 

I recently changed security settings of my external harddrive (f:) so only me (Administrator) can access it, there was a long number that was listed as owner and I changed owner to me (Administrator) and followed steps to take ownership.

 

Now Norton Security Suite can't find external harddrive (f:) to do backup on, even when I click on refresh list of backup locations in the Manage Backup Sets panel.

 

System - Windows XP Pro version 2002 service pack 3 

 

Your help will be greatly appeciated !
