How to create new volume?

[adam2008]

I just installed Windows 7 on a 100Gb partition after a lot of trouble getting it to work. Anyway it all runs fine but I can only use the 100Gb partition for storage at the moment how do i get my other 900Gb's back? I can see in my HDD properties that their is 900Gb's with no drive letter assigned to it, so any help on how to reclaim my other Gb's would be good.

Cheers, found disk management and got all the space back

Is there anyway of making it appear as though both partitions are one, so that any documents saved on E: appear in my documents?
