I was cleaning the dust filter on my server when I accidentally hit the power button when trying to snap the front door on and it shut off. I turned it back on and it seems fine but should I do a parity check? I literally just finished one 2 days ago.

Is there anywhere I can get the complete series on bluray? I know EBay but how do I know if it’s just a copy and not original discs?
