I tried 3 searches and 3 failed after about 45 Seconds, saying it got an error looking into the Spotlight indexs. Other Find Programms like FileBuddy finds all files within about 7 Seconds on a 80GB rather full disk. Now thats fast. I do not agree with another comment, Spotlight or Command+F is enough! The author states correctly Spotlight will intentionally omit some of the HD. But Spotlight can be extended by the use of "NotLight" which uses the Spotlight index and is better configured. Though the interface or search criteria is not easy to grasp. But the NotLight programm is really good. And if I want to use Spotlight to search ONLY for a NAME, I type e.g. "Cargolifter into the Spotlight field. So just add one " in front of the name and Spotlight ONLY searches for names. But still FileBuddy is really fast, can be tuned, can be limited to a drive and much much more.
