[EDIT] checked the jumpers, one was on wrong. case solved, sorry for the waste of time to anyone who tried to help.

What version of windows do you have? If it's Windows 98 then that's the largest it recognizes

tinyxp is a small version of xp designed for computers under the recommended specs. for example, i run it on my 500mhz home pc. its xp but it has a lot of stuff [like drivers] removed.

this is so funny! upon further inspection, one of the jumpers was on sideways, i misread the diagram on the hdd so it wasnt on master, infact im not sure what it was on.
either way it reverted to a 32gb size. as soon as i put it right the other space appeared. im re-formatting and reinstalling now.

Congrats on figuring it out, sometimes it's always the simplest of things
