I have a Mac Mini (latest model, only a few months old). I use it as a Media Centre. It has a few external USB drives connected with all my media. Every time I try to do something in Finder, every time I double click a folder/drive, I get a spinning beach ball with the mouse pointer still showing (pointing to the middle of the beach ball). It only lasts a few seconds, then everything seems normal. It seems to happen no matter which drive the said file/folder is on (including the internal HDD). I've got a SMART utility running (with driver installed so it can see external USB drives) and they all report clean health. Any ideas? Thanks!
