Sucess.installed clean image as suggested. Reformatted usb stick into 3 extensions plus HARD DRIVE. ext.1 sdb1 universe 6290 mb. : ext.2 sdb2 media/usb 4194 mb. : ext.3 sdb3 media/downloads 5539 mb. : hard drive sda1 1000gb. All mounted no problem. Tested by downloading ts panel . ram at 47% and flash at 1%..I made a test crash and it showed up in HDD.It looks to me that my initial problems with HDD not mapping were due to me not including HDD when formatting usb.Now my question is. Have i created the correct extensions as i have mounted 2 media locations i.e. usb and hdd.As you can see i now have unbelievable space available if i have created the correct extensions.
