Ok, so after some more experimentation, I think I found that the reason it was dying was due to a file being too large. When I run it on a smaller dataset, it seems I am successful in getting past the WriteRaster command in my code.
The bad news is that it doesn't seem to be working properly. It seems to write the first band correctly, but bands 2-5 are written incorrectly. The buffer I'm using checks out before and after the WriteRaster command. So it has got to be something with the WriteRaster command that is not working. I've played with the offsets and all, especially the bandspace, linespace and rasterspace arguments. Anyone have similar problems, or any ideas as to why I can't get the WriteRaster to work? Thanks!

I don't know what is going wrong.
