Hi Eric,
Shouldnt it be around 54MB/s for a regular IDE drive.
Here is the output of dmesg and iostat
[..snip dmesg blob..]
IOSTAT

(please try to avoid top-posting, it's hard to follow)
What about other block sizes? Also - you should paste your actual dd output here too.
What's the model number of that drive? Maxtor claims (on one of their 160G drives) 17.8MB/s from inner diameter disk and 35.6MB/s for outer diameter for the 5400rpm drives.
