I may have found part, if not all of the problem.
When I bought the Hard Drive today I asked if he had a Sata data cable laying about ... he had a box full and included it free of charge saying he didn't know if it was working ... well, it might not be ...
I removed the data cable from my DVD RW plugged it onto the second hard drive and started it up ... in This PC it was showing C: and New Volume H: 148 GB free of 150GB
Replaced the data cable back on the DVD RW ... now shows Local Disk C: and DVD RW Drive H: as it should do.
1. Assuming it is just the cable causing the problem, is there anything else I need to do prior to adding my folders, files and photos?
On the Motherboard there are 2 x Sata 300Gb/s and 2 x Sata 600 Gb/sec - 0,1,2,&3 Two grey and two black - I don't know which is which - DVD is on 0 (Grey) and the 1TB HD is on 2 (Black)
When I tried the "new" data cable on the "new" HD and on the DVD RW it was plugged into number 3 (Black)
2. Could it be the 1 & 3 data sockets on the motherboard need some input to get them working?
