Incorrect partition size

A strange one here. I recently installed a 200Gb system drive which has formatted fine etc. Windows shows the full capacity, Disk Manager shows the full capacity in the graphical bar thing but has it listed as only 128Gb being available when attempting to create a new partition or resize,(There is no unallocated space listed) Does anyone have any ideas ?
