Macbook Pro Hard Disk Loading Sound

[Manjey Puirtili]

I recently bought a MacBook Pro and when I click to start/load programs (like opening iDVD, Firefox, VLC player etc. etc.) or when I copy files from my external hard disk to my MacBook Pro, I notice a series of low sounds (like clacking). These sounds are heard only when loading/starting programs, otherwise the notebook is very silent. I'm sure these sounds are common in other laptops/desktops (esp. desktop hard drives) but just wanted to check if this is normal for a MacBook Pro. Thanks.

thats just normal drive chatter, this sound happens as the head or heads rapidly sweep accross the platter or platters to access or write data on the hard disk...totally normal...

I'd be interested to know what make the hard drive is.

Don't have my mac here right now though to tell you where to look.

Would be in system profiler somewhere.
