If you see only 8GB, you have done something wrong when connecting the drive. Such large drives usualy have a jumper that limits the capacity to 8GB for old BIOSes. You have to remove this jumper.
This isn't strictly true. I have an 18Gb HD. HDToolbox 3.1 could only see it as 8Gb no matter what I did (there are no jumpers on it to set the size). When I installed OS3.9, that HDToolbox saw it as the full 18Gb HD.
The 3.1 HDToolbox should be able to partition the drive. But it will show some strange numbers for the size (e.g. negative). Better you use the 3.9 HDToolbox or HDInstTools.
HDToolbox 3.1 (as far as I know) has a limit to 8Gb. It will not allow you to partition a drive bigger than that. 3.9 however will partition the HD quite easily.
