i purchased a new MBP last week, and it is working great! but over the course of last week, i installed and uninstalled tons of junk programs- norton antivirus, photoshop trial, and countless other stuff. all this install/uninstall must have defragmented the HDD.. i was just wondering how can i defragment my volume. thanks a lot, im a new comer to mac, so i dont know how to work my way around mac os 10- spotlight didnt give any programs for defragmenting
