Just switching to Mac, and I have old ext HD drives formatted in NTFS. They are seen and mount on a Mac with Snow Leopard, but on my new Macs with Lion they don't show in Finder. They do show in disc utility though. Curious to know why. As it is, as I migrate the data, I will reformat all my externals to Mac. I have Paragon installed on Lion but not on the SL machine, and I know that Paragon is required to write and not just to read/see the drive. Any ideas?
