Hi, If I were to form my second HDD in my PC as a backup drive for my first, could I too utilize it to save stand-alone documents? Commonly I have about 500GB of information on my 1TB system drive. I need to back that up onto my second drive. However, could I too utilize my second drive as say, a scratch drive whilst video editing, or to record footage from a display recorder similar to FRAPS onto? Or must it be exclusively for backup?
