You know.... for some reason WD doesn't set their drives to high speed by 
default! ????  For instance.... I loaded up their software disk to test the 
180gb because of all the errors I was getting. It passed. I then went digging 
around the other utilities and low and behold my old 100gb drive I've had for 
a year or so was running at 66. So was the new 180gb drive. I bumped them 
both up. This seems to have sped up the perceived performance. I did NOT run 
benchmarking tests on it though.
