I'll add to whats already been said and say that the reason WHY you are having space difficulties is because of the single "huge" partition sizes.
Partitions of the size you are using is VERY wasteful. I won't go into any detail as yet but basicly your drives have a minimum cluster size of 32KB. This "cluster size" is the MINIMUM amount of space ONE file will use and only ONE file per cluster. So, assuming 32KB clusters, and assuming a 1KB file, 31KB of space is wasted because Win9x/DOS (samething really) can only "store" one file per cluster.
You can check this by doing the following:
1. Open "my computer".
2. Select any hard-disk and right click for properties.
3. Look in this properties for "cluster size" or "allocation unit size"

Now, get a jest of your "typical" file size.
To make matters look really bad, check your "internet files folder" where Micky$oft stores web page bits. These are usually small files of 1-3KB. Add the number of files you count and multiply by 32. Total the space needed by these file with a calculator. This is the "raw" space needed but not whats used.
An example:
100 files, 2KB in size each= Thats 3.2MB of allocated space using 32KB clusters where the total actual space required for the files is 200KB. *ouch*

I can go into gory detail as to "why" but I dunno if I can apply the KISS principle.
