I bought a Freeagent to store my games and a couple of my programs. One day, I decided to reinstall Photoshop from the external HDD but it gave me an error. Not a problem since I thought I could download it again but then when I tried to reinstall other programs like Office, it keeps giving errors. In fact, one day, I copied Autocad into the HDD but even though it installed perfectly on my normal HDD, when I tried to reinstall it from my Freeagent, it kept giving errors. I shudder to think that every program I have on it is corrupted which is why I'm thankful for blank DVDs but what could be the problem causing this?
