I was trying to extract data from my old hard drive that used to be from my old Dell Dimension 4600 (The PC's now used as a Vista media center). This old pc still has XP Home Edition installed in it, and I'm just trying to get to the data. After installation, I only got the free space and nothing from the used space (the drive is blank when accessing it through "My Computer"). Do I have to use a USB hard drive enclosure to get that data out?
