Earlier this year I wrote about Accessing Mac Hard Drives from Windows 7/8: Boot Camp Support Software 5.0.5033 and mentioned that there are also a few solutions for writing NTFS volumes from Mac OS X.
Thanks to dhardy03, I learned that Seagate now provides NTFS drivers for Mac OS X for Free. The installer name indicates it is an OEM version of the Paragon NTFS drivers for Mac OS X.
I’m not sure yet if it works only on Seagate drives, but since the only other HDD manufacturers left are Toshiba and Western Digital (Toshiba is a much smaller HDD manufacturer than WD and SD), it is a substantial part of the market.
I might try NTFS-3G as well, but that hasn’t been updated for a while and has been replaced by the commercial Tuxera product.
