Apple admits beep, click and pause in MacBook Pro 500Gb 7200RPM drives

According to CNET News, Apple is working on a software fix for a bug in MacBook Pros with 7200RPM 500Gb drives which causes a beep sound, clicking, then the machine pausing temporarily. I know of at least one instance where a new machine was replaced under warranty for this problem, so it will be interesting to see if there’s a software fix.
