Hi all,
I have been looking at the speeds of the disks in some of the threads
lately. I noticed that mine is a lot slower than most. I have attached
some info. Is my disk running as optimally as it can or is there some
more tweaking I can do to improve performance?

What other hdparm flags can I _safely_ use, I don't want to trash my
disk.
Thanks and Regards
Craig
