Glad to see this worked out for you Bob and thanks to Raydon and CF you’ll be able to keep on top of things.
The boxes shouldn’t have got into this state in the first place though. Unless there are lots of power cuts, I’d hazard a guess that the boxes aren’t being shut down properly. They have to be put into standby, wait for the disk to stop and then they can be switched off. A power cut or simply pulling the plug/mains can lead to file system corruption. If any hard drive type problems persist then you’ll need to take a look at the SMART stats from the disk
