Strange hard drive problems

[zDonaldson]

Hello, I'm getting some strange results in HD Tune Pro with my new HDD. It's around 130 mb/s or so at max, but it likes to drop down to 1 mb/s randomly, giving my system a noticeable slowdown. My old maxtor only gets about 60 mb/s but it doesn't get that low. Please help.
