Might be the frequent unload bug.

Check with smartctl your unload cycle count before and after noise: 
Start_Stop_Count or like (mine is labeled as Load_Cycle_Count).

If it is increasing, you might be able to fix it with the right hdparm value. 
If not please report.

I personally got a 100k value (300k lifetime) with a Toshiba MK8025GAS in only 
few months :/
