I assume the computer is on a home network and not on a domain. Are you trying to access data on a different HD or partition? What OS was on it and what is the current OS now? I assume it is either NT, 2000, or XP. If it is one of these, do you have administrative rights? Can you right click on the folder and change the permissions to give everyone full access? If you answer these questions, it would be a little easier for us to troubleshoot.
