Building the MFT first is pretty much what I want to do. But I'm not aware of any utilities that can handle it, nor where to start with writing it myself... I have a project where I routinely need to copy large amounts of data (3 to 8 TB) to a hard drive. Problem is, my files are all 512kb. So this is much slower than it could be... If I write it as a single tar file I get excellent throughput, but the users who need to be able to work with the drive are unable to handle a tar file. They need to be able to plug the drive into a Windows computer and have it "just work".. which presents some problems.
