I'll be sure to update here if I get to the bottom of it. Chkdsk didn't take that long. I wasn't watching it but I came back upstairs after an hour and it had completed, I don't know specifically how long but there was nothing found. I was able to run it from within Windows. I followed the instructions Disk Check here but unticked both boxes to just get a report of errors did exist rather than try to fix/repair/recover. It did go quicker than expected although I am not experienced with this type of troubleshooting - I did think it was going to be another all evening affair!
