hey guys, currently using a mid 09 13" Macbook Pro with 4gb of ram. Currently i have a Western Digital 1TB My Book External Hard Drive connected to the usb port. But everytime i try to access the ext hdd, there will be the dreaded beach ball ands takes around 3-5mins before the files can be displayed on finder. I never had this problem when it is plugged into my windows PC. My ext hard disk is currently formated in NTFS, im accessing the files through my mac using NTFS-3G. Could this be a reason?
