I now have that secondhand NUC6i3 I mentioned. Not turned it on yet, but the seller tells me it already has ROCK installed. Should I wipe it and start again with a fresh ROCK install, or should I use the existing one?
Gut feel says starting afresh will take longer initially but should mean less problems going forward (if so how do I wipe it - ROCK newbie here)
I would recommend just reinstalling the Operating System (as Geoff suggested) and resetting the Roon Database & Settings (which would remove and database information from the previous user if it’s still there). From there you can start fresh and install one of your existing Roon database backups and be good to go.
