I just ran the Benchmark test again, and am now told that ALL FOUR disks are performing well below expectations. I had my suspicions, as some finding functions seemed slower than usual.
On a happier note:
By a stroke of good fortune, I now have a GPU which is performing above expectations. Yesterday, FSX running unlimited, displayed 95fps. I'll check now whether the cable shemozzle has had any bad effect.
