I have been faffing about for two days now trying to find a decent guide/video about what happens after you have installed Amahi, how to load apps etc and why does it say they're not available etc setting up apps and shares etc a basic guide. I have been in IT for over 25yrs and pride myself in know...

As a complete newbie but eager to learn, how the heck do install "disk wizard" so I can add an "icy box" 4 bay external hard drive to my server?
