I have been using Hitachi drives for about 5 years now in both my laptops (3) and desktops (5) including a dual 1Ghz Quicksilver and a dual 1Ghz MDD. I have had no problems with any of them.. I select the drive I want and then buy them wherever I can get the best price (google the part # to start looking). The link below will take you to the Hitachi page with compatible drives for your machine. I don't understand why the drive would give you these problems, though. You say you have two drives installed. I would try swapping their positions (be sure to watch for jumper configuration) and see if the problem follows the drive to its new position or if the other drive now has the problem you describe. Maybe a cable or connector problem.
