This is my 2010 macbook pro 13" 250GB beeping HDD. It does it randomly, sometimes every few seconds, sometimes once in a few days. I checked it with Disk Utility and also with TechTool Pro 5...both claim its OK
it is a bug with old firmware that controls the safety mechanism in the HDD to prevent fall damage. it should be fixed by updating all the system software with Software Update.
Did you ever figure out what's wrong? Mine does the same thing...
