Thanks for all your input on my recent threads about my plan on purchasing a new external harddrive. Just an hour ago I went down to the nearby best buy and purchased a Seagate 100gig external portable harddrive. I am very happy with its portable size and harddrive capabilties. HOWEVER the main reason I bought this was the hold al lmy multimedia files such as Divx movies and music etc, but when I read the manuel they said it is not reccomended to share files between Mac OS and windows. My macbook pro has both and what I wished was to watch movies and listen to music on both OS's for convenience. There are directions in setting up the harddrive to share both but they said I need 3rd party software for windows to read Mac files. Can anyone help me out with what program I would need? And has anyone who has done this before ever have problemS? data loss etc. Well thats all for my questions thanks for your time.
