The theme "Tropico", (http://www.litestep.net/upload/themes/Tropico_OTS2_327-293.png) along with a few others, have built in monitors for hd, cpu, net, etc. etc.

They all work fine except for the hd monitor. It's completely empty, and my hd isn't empty. I also have two. My guess is it can't figure out which to reference. Any idea what line in what file I might edit to fix this? Thanks.

ha, nevermind. I found it. For anyone else who wants to know, it was a file inside the theme folder in the config folder called "Rainmeter" and the line looked something like this:
[MeasureFreeDiskSpace]
Measure=FreeDiskSpace
Drive="F:\"

It was set to E:\ when I found it (that's my DVDrom drive o.0 So I changed it to my storage hd, which is the one i'm more interested in, and then just right click and refresh on litestep.
