Problem Creating Raster Dataset

I am running into an issue creating a new raster dataset using the Extract by Mask tool.  Specifically, I am trying to use a polygon to extract a section (a single watershed) of the National Land Cover 2001 (v 2.0) dataset (  The NLCD 2001 dataset is a .img file.  The NLCD is a large file, so I have set the Extent settings in the Environments to be equal to the extent of the polygon to ensure the result of the extraction will not be too large.  Whenever I attempt the extraction, I am consistently getting this error:

Could not save raster dataset to C:\Temp\g_g_g5 with output format GRID.
Failed to execute (ExtractByMask).

The error suggest there is a problem in converting form the .img to the GRID format.  Is this the case?  If so, is there a way to get around this? 

So far I have tried:

1) Ensuring that I have the latest Service Packs installed
2) Rebooting the computer
3) Turning off the Spatial Analyst extension and then turning it back on
4) shortening the names of the raster and feature input files
5) placing both the raster and feature file into the same source folder
6) Changing the output destination folder
7) specifying the scratch workspace as "C:\Temp" in the Environments setting
8) Clearing all the files from the Temp folder to ensure there is enough space

I greatly appreciate any solutions that folks might have.
