New Macbook Pro, 160GB 5400RPM Fujitsu drive. Several times a minute I get a clunk sound from my drive. Its pretty quiet-I only hear it in a near silent room. Ive got it set to never spin down the drive, so its not that. I have activity monitor going, displaying drive usage, and it seems to clunk a few seconds after the usage drops to zero. Im guessing the drive automatically parks itself or something when its not reading or writing. Ive read some random threads on the internet with other people with clunking Fujitsu drives. Just wanted to see if everyone elses does this too.
