Thanks, Luke..

I take your statement to mean that I could step through one of the numerous
examples of hdparm tuning on the web (Such as
http://tldp.org/LDP/solrhe/Securing-Optimizing-Linux-RH-Edition-v1.3/chap6se
c74.html) without causing any damage?

Also.. for my setup, sda is the Windows XP side (NTFS). Should I only mess
with the linux side (sdb)?

Thanks

Tony

That said.. I have one question. Is it possible to tune a dmraid disk in
the
same way that you would using hdparm? If so.. What are the steps involved?

Yes, you would use the device node of the disk or disks that are part of the
array. So hdparm -d 1 /dev/sda would enable dma for sda, the first drive in
the array. I don't think trying to do this with the device mapper nodes
would work.
AFAIK only a small subset of the hdparm parameters work for sd devices. I think you'd be better off with sdparm.
