I wonder, with the new OS next year, if Microsoft is going to improve the file system for stuff like this.
They were. WinFS (Windows File System) but have since dropped that for the time being due to holding up development.
NTFS and all your worries are gone....and so is multiple OS/cross platform support.
Someone mentioned NTFS has licensing restrictions, could be another reason no one uses it?
Sure would be cool to have the option to format to NTFS in the MicroTrack in a firmware update. Hint Hint!
