Incorrect Hard Drive Space reported

My computer running Hardy amd64 has two hard drives, an 80GB one with a 37GB partition mapped at / (The rest is a windows partition), and a 204 GB Drive, mapped as /storage. However, when I try to use the Disk Usage Analyzer or when a program tries to install in wine, it reports a total hard drive size as roughly 80 GB, but still includes data on my 2004GB drive towards total usage. As a result, I'm reaching a point where program won't install, especially in wine, claiming I don't have enough space, even though I have 200 GB free
fdisk -l gives the following information:

with sda being the drive with / and windows, sdb being /storage, and sdc being a flash drive.
Any help correcting this issue would be greatly appreciated
