After a lifetime of owning PC's I finally purchased a MacBook Pro running OS X. I installed Parallels Desktop 5, Windows XP, and several Windows apps to have dual functionality. Now I need to write to my NTFS ext. hard drive where I backup everything. It has 800gb of space left, so it would be a shame to get a new one just b/c I have a Mac now. So...I first installed MacFuse and then NTFS-3G. Now when I reboot, the ext. HD won't mount at all. What have I done wrong? Please and thank you.
