I have a 3TB Seagate Desktop HDD on a XP and when I boot the computer up the loading screen displays both HDDs in the computer and at the correct size. However, in My Computer the HDD isn't displayed. I downloaded the DiscWizard from Seagate and that displays the HDD at 2TB only. I partioned it from the software and rebooted, but it's still not being displayed in My Computer. Can someone explain to me step by step what I need to do to be able to use it even if it's just the 2TB worth.
