Did a little more reading and a bit of digging around in the unraid gui and found it was reporting an error on the parity disk that was historical. Clicked on the little warning triangle in the drives list, acknowledged the error and as many have said in other posts, the error hasn't been notified again. Should the drive encounter this error again, the smart value will change triggering the warning in unraid again. When that happens I know it will be time to replace the drive but for now, all is good. Thanks for all the replies. They helped me a lot. Slowly getting my head around it but liking the functionality a lot.

Thanks - guessing it is the parity drive then, All the data drives are new external drives but the parity is one I've had for a while now. Guess I need a new replacement. Probably go for a NAS specific drive this time. I bought the external drives as they are at this moment in time, the cheapest way to get 4TB disks. As for sudo - it's a habit from using raspberry pi's on 3D printers. just got in the habit of using sudo when needing root access Really appreciate the swift response. Everyday I learn a little more thanks to this forum.

Background..... At present I am stuck with 100Mb powerline adapters and am waiting the arrival of 1Gb adapters so transferring hundreds of large RAW files will take an age using the network. I am still in my first week of using Unraid so I'm not very experienced with it. Workaround...... I am copying the files and folder structure onto a small NVME drive which is in a USB3 adapter then plugging the adapter into the Unraid box and copying to the relevant share using the command line i.e. 'sudo cp -E -R /mnt/disks/NVM/Photos /mnt/user/Media/Photos' This copies the files to exactly where I want them in a fraction of the time it would using my current network speed. The question is - By copying the files this way which I am pretty sure is bypassing Unraid, be the cause of the parity errors and subsequent parity chesk that occurs ?? To me. logic says this is the case as the files are being dumped in the share with the Unraid software having no knowledge of the copies and when it does it's checks flags the discrepancy in the parity drive. It seems to be rebuilding the parity and updating the parity drive while the array is still live.

Hi to everyone, I'm new to the world of NAS and having suffered the temporary loss of data due to dying drives and one one occasion, ransomware. Fortunately I had 90% of the data backed up but lost some photos from a holiday we thought would never happen. I've tried some of the other solutions out there but could never get them to work intuitively and eventually stumbled across Unraid by watching Linus Tech Tips videos. I was initially disappointed that there wasn't a free version but after a couple of days trying it out to see if I could get my head around the system I've already decided I will be making a purchase. This is one of very few pieces of software that I feel is worth investing in. I made some mistakes while trying to find may way round and have managed to sort them out with advice found on this forum, youtube and even (surprisingly) by myself. One mistake I made would have resulted in having to start again and having to transfer the files again if I had been utilising the free raid systems I had previously tried but with Unraid I was able to recover the existing configuration. Making regular images of the USB drive after any substantial change, while being time consuming has saved the day a couple of times. I'm not a big fan of any 'nix' OS though I do appreciate that in the server world they excel. I just don't have the patience to learn enough to make it my go to for my personal use but Unraid does a lot to hide the underlying structure and the little I do know has been enough for me to do some small tasks that either aren't covered by the web interface or are covered but I've not yet discovered. I'm taking it all step by step, initially getting the array up & running, setting up shares then adding a couple of plugins with a plex server. Now trying to read up on VM's though I think I might wait on adding VM's as I may want to replace the motherboard so I can add some extra ram and maybe add a graphics card (the PCIe x16) slot on the existing motherboard appears to be dead). In summary, makes setting up a NAS pretty easy, even for someone like me with very little to no knowledge at all.
