I did as suggested and updated firmware successfully but still had same result when connecting external USB drive. Also that I check that the USB drive was shown as a shared folder (Control Panel > Privilege > Shared Folders) Next stage was to open a ticket with QNAP who suggested that I update the firmware to the latest version (standard expected answer) then connect the USB drive and see if allowed it to mount correctly and be seen in Filestation. I did try storageman's checks without success and also tried a different docking station too in case that was a factor but to no avail. Thanks storageman for the tips and for anyone following up on this I have the following update and conclusion Using Putty and "lsusb" would definitely confirm it is seen.

How you tried clearing the browser cache or connecting from a different PC? So has anyone any suggestions of actions or checks to make please, I'm not a linux guru so if commands etc are needed then I'd appreciate some idea on the syntax etc as well

The NAS seems to be working ok, other nightly routines are good and no one at home has complained of problems using Plex, so I'm taking as an indication of systems being good. Lastly I have tried using a different USB port in case thatwas related but no change, so it does look like there is something messed up in filestation I did think it might be related to the external drive but I have the same result using a different backup drive - both these work ok in the other serverI have access to. In addition it then does not show in file station as being connected at all, all I see are the folders etc in my datavolume (external drive 2 pic) When I connect it to my main NAS then I can see it as connected under the icon on the top of the admin workspace ok, however I do not have the option to open/view the drive (external drive 1 pic). I have checked the backup drive on another server and looks good with no obvious problems. Sure enough when I looked at the backup job settings the source folders and the destination path details were completely messed up (external drive 3 pic)- no idea why and can't see anything in logs to indicated any errors during the days leading up to it. Two nights ago my regular weekly backup failed and indicated that the folder pairs were invalid. Bit of a puzzler thatI hope someone can offer some guidance on.
