Feature to Raster issue

Hi-

I have a vector shapefile with an associated attribute table, and I'm trying to convert it into a raster that is classified by the values in one of the attribute table columns.

From what I can tell (based off of what I know and what I've read), all I should have to do is go to Conversion tools>>To Raster>>Feature to raster, and enter in my shapefile as the input feature, the desired attribute column as my "field", and then name the output raster. The output cell size is generated automatically, and it has a value of ~621, despite the shapefile being at a pretty fine scale. I've tried saving it in a geodatabase, and tried saving it in another file as a .tif, but no matter what I do, the output file has HUGE pixels that do not accurately represent the data, and the pixels are divided by value into 9 different float classes, even though there are only 4 different values in the input attribute, and they are discrete integers. I've included a screen shot of what the original shapefile looks like, and the appearance of the output file.

Can anyone tell what's going on here? I would appreciate any help you can give. Thanks!

Emma
