I went home and lunchtime and tested it, worked a treat. I left it running gparted formatting the whole drive as EXT3 when I came away. I'm so chuffed its working!
Once again sorry for posting about a hardware issue but I guess it is relevant to linux users in that the new drive required a firmware update to force it to work at the required speed to work in the POST section of the raid controller boot process (and thererfore in Ubuntu) whereas if the same drive on the same controller is hotplugged into windows (bypassing POST detection hang) it managed to work. Incidentally I also hotplugged it into ubuntu ATFER the firmware update just to see if ubuntu likes hotplug sata and it worked a treat. So the moral of the story is, if you get a new samsung sata drive and want to run it on an (slightly) older mother board like mine with sata1 support only (up to 1.5Gbps) then you need to download a utility from samsungHdd.com and connect it to a newer (sata 2) controller and flash it accordingly (there is a utility to flash it back to sata2 if required also). I would have prefered the older pin and jumper method for backward compatibility but there you go. Hope this helps.
