Hi, everyone. I got a refurbs DSR704 from Directv. I am planning to mod it with a bigger harddrive. What should I do next? Could I backup the hard drive before I activate it? And how? Thanks so much! Update1: I did a little bit research. Since I only want to upgrade the drive first, I would need to download "Mfs Tools Boot CD". Update2: I havn't activated the DSR704. Should I activated it first? Should I upgrade the software first? Thanks! Update3: I have activated it. The software is 3.1.1e-01 Should I upgrade the software first? Or do a backup first? Thanks!
