  ==TFAT not covered in ExFAT section==  It appears ExFAT has a variant known as TFAT.  http://msdn.microsoft.com/en-us/library/aa915463.aspx  There is very brief wikipedia entry at http://en.wikipedia.org/wiki/Transaction-Safe_FAT_File_System  It would be nice to have a line or two here, a pointer to the other article, and may be some work on the other article if anyone is up for it.
