HI Neil, yes I had also sought to rule out the USB ports as being suspect and I inserted a known good USB thumb drive to Jo’s MBP which immediately mounted per normal. So I believe the USB ports are fine it is just the relationship with this particular HDD external drive and the MBP is where the issue lies.
I did a Basic erase and reformat of the drive which still resulted in not being recognised and am now in the process of doing a Secure erase - takes a fair bit of time. I’ll have to wait for that to finish. If that is unsuccessful, I will try the recent tip Ronni sent with the System information screen and Activity monitor. Will keep persevering with this thing and advise further results.
