Seriously, for the life of me I cannot find it. I've looked in System Profiler and Disk Utility to no avail....am I overlooking something here? I thought it would be obvious; I simply want to know what the RPMs of my installed drive are. thanks ps Amazing how a 320gb drive only registers about 195 or so...is that right? I know when the drives are formatted they don't register the full capacity but losing 25gb seems a tad much to me.
