I built a Xpenology server on a HP 495 platform, using a tiny Kingston stick as boot stick. I was running just fine, downloading happily with the installed SABNZB. The server doesn't run 24/7 but gets switched of every evening. Yesterday it was switched on and after connecting to it with SA I was greeted with a blue screen, the last line saying configuration lost. What can be wrong here? Is the stick corrupt, or is the configuration on one of the harddisks? More importantly, how can I fix it and get the server running again without losing data? And how to prevent it happening again? What is the right procedure? Please help.
