sounds like the HDD. I think you should right click on MyComputer and then left click Manage.
Go into the drives and choose your external drive and read what it tells you. You may just be able to reformat but I really think you should look into buying one of those 89.00 1 TeraByte drives and put it in your old case. Its possible that the case electricals are hooptie but it's not likely. See if you have an old HDD somewhere to plug in your case before you decide to get the new drive.
