So moogs did you get the drive sorted?
if the drive is recognised in device centre then the all you have to do is open up c'command prompt' and type 'diskpart' the 'select disk 1' or whatever 'device centre' properties says it is. Just double click the drive and select 'volumes' then click 'populate volumes' to find the disk number. Once done then type 'create partition primary' and then finally type 'assign'. Then it will show up in my computer for you to format, You will need to have SP1 installed to access drives over 130 GB.
