I see two issues here.
1. You may be using your machine as a Defragmenter rather than a PC. In short, yes, you boot the OS and a fragment will appear in some place and some where. It usually only bothers a small percentage of users that seem to want with no fragmentation. How can I write it nicely that such is not going to occur with this OS?
There should be nil effect until you do something big like install/uninall a few programs, but there is a XP Microsoft'ism in that DMA often falls out to PIO mode and a simple procedure can help.
If you do not do the procedure and indicate you've completed it, then explain if I am unclear or if the article is not clear.
PERFORM THIS SIMPLE PROCEDURE -> http://www.microsoft.com/whdc/hwdev/tech/storage/IDE-DMA.mspx
TO REPEAT -> If you look, but don't do this, then you are not assured that DMA is enabled...
2. The PCPITSTOP scores are usual best of the best and not your machine. To match the PCPITSTOP scores, go get the hardware they used and exact drivers and such.
I can safely bet you have a firewall, antivirus and more runnign during the benchmark which the other users didn't to score the highest they could. But I wouldn't fret over "uncached" scores since we don't run the drive in this mode.
