Well, I first changed it to NTFS and it was great. Then I decided to install XP over Win2K...bad idea. it really screwed up everything...in fact, it kept rebooting the PC endlessly. So I went back to Windows 2000, formatting the PC, this time choosing the option for NTFS.
As of now, I have not noticed any improvements, except for some new options and such. But hey, at least its working ok!
