Darn it! I managed to break my SD card that came with PiDrive. Just when I had gotten up server up and running. So how can I reinstall Raspbian on another SD card so that I can still use the existing installation on the PiDrive? I did the default install with the included SD card with just one partition and no extra project spaces or anything like that.
Did the default SD card do anything special with the install or can I just follow some instructions on how to boot from external hard drive? There are a lot of those around (I did do it earlier with another drive before I got the PiDrive).
