Hi All. I had Parallels advanced technical support set up my MacPro with an internal 500 GB HD running Win XP so that my other 500 GB HD that I am now running Snow Leopard on can access this system using Parallels. I am just now getting around to try and streamline this setup and from day one when Parallels is on there is a CONSTANT CHURNING of my Hard Drive. This does not seem normal but I am not a big tech head. Anybody know what is going on or what I should be looking out for? What is the "prlvm" (spelling?) or whatever it is that I always see in Activity Manager when I try and check this?
