My mistake. Is there anything else I can tweak to get more of this drive's performance or am I stuck with what I have? My read of your default UDMA/100 comments is that it's a safety net type setting for the 3112. Would bumping this to UDMA/133 give me any improvement over the PCI bus? Is there anything else I could tweak?
