Consider ActiveFat Field in exFAT filesystem #34

Open LeavaTail opened 3 years ago

LeavaTail commented 3 years ago

Is your feature request related to a problem? Please describe. According exFAT specification,

The ActiveFat field shall describe which FAT and Allocation Bitmap are active (and implementations shall use), as follows:

  • 0, which means the First FAT and First Allocation Bitmap are active
  • 1, which means the Second FAT and Second Allocation Bitmap are active and is possible only when the NumberOfFats field contains the value 2

Implementations shall consider the inactive FAT and Allocation Bitmap as stale. Only TexFAT-aware implementations shall switch the active FAT and Allocation Bitmaps

exFAT specification said,

Only TexFAT-aware implementations shall switch the active FAT and Allocation Bitmaps

So This feature is low priority.
