I've been using a Seagate FreeAgent 500gb external for almost a year with Paragon NTFS for Mac. Recently I've switched to NTFS-3G because it seemed to have faster performance than Paragon. But a couple of days ago when I plugged it in, my Mac popped this message up: I went into Disk Utility and this is what I saw, . It doesn't have any info on space, or anything really. I underlined (NTFS-3G) because I thought maybe the Pref pane, NTFS-3G might have done something to the Drive. I suppose it should just say "Windows NT Filesystem". On a windows computer I got this dialog box. But my drive was working perfectly fine a few days ago! If anyone out here could give me some advice or help on what to do, that would be wonderful! I simply have no idea why it decided to not to work and I have some very important files on my drive.. I'm running on an early 2008 Macbook Pro, with Leopard OSX.
