UPD 21.08.2011: There is even better way to solve the same issue with native Mac OS X drivers, but it has its own pros and cons. Read at the end for details.
UPD 12.09.2011 (IMPORTANT): Native driver makes NTFS unusable. Read below for details.
Mac OS X Lion (10.7) was released recently, in the end of July 2011. And many users had started to complain that their NTFS disks stopped working. And the much worse problem is that “old” solutions do not work well.
But after one or two weeks of researching of this issue, I’ve managed to make NTFS work in Mac OS X Lion (10.7). The key here is a proper combination of software versions.
So I will shortly describe the usual choices for external data storages, and what problems arises with each of them. And later I will show how you can get the most universal way — NTFS — to work where it does not work by default, with links and pictures.
