Is it normal for a new 2.0DC PowerMac running 10.4.3 that was just awoken from sleep / 10-15 mins of inactivity to momentarily freeze or "think" (spinning umbrella icon) when accessing the HDD? For example, I don't turn my Mac off at night, I just let it go to sleep, and in the morning I awaken it to listen to iTunes before I head to work. If after awakening the Mac, I double-click a song on iTunes (already open), it'll take a few seconds (and I'll see that spinning umbrella icon) before it starts to play. Sometimes I'll run into this after leaving my PC for ~15 mins (not enough time for it to go to sleep, but enough time for the monitors to turn off). Now this issue is most apparent in iTunes, but happens sometimes while just accessing a file / folder in Finder. My iTunes library is ~20GB and is stored on a 160GB Seagate HDD in the "B" slot. My system has 1.5GB of RAM and I've set my HDDs to never sleep (before I thought this was the problem). Anyhow, it isn't a huge issue, just a minor inconvenience (I'm rather impatient ), but I don't think a system of my specs should have these issues. Just wondering if this is normal or not, or if there is something I can do to optimize the performance.
