/*
* $Log: V:/Flite/archives/TrueFFS5/Src/FLFORMAT.H_V $
*
* Rev 1.9 Apr 15 2002 07:36:52 oris
* Bug fix - Standard format was changed
* - includes only 1 Disk partitions and not 2.
* - leave 2 spare units in case power failure occurs while writing into the last unit.
*
* Rev 1.8 Feb 19 2002 20:59:52 oris
* Changed default spare units to 2
*
* Rev 1.7 Jan 21 2002 20:44:44 oris
* Changed comments.
*
* Rev 1.6 Sep 15 2001 23:46:24 oris
* Changed progress callback routine to support up to 64K units.
*
* Rev 1.5 Jun 17 2001 08:18:54 oris
* Changed exbFlag field to word
* Added typedef FLStatus (*FLProgressCallback)(int totalUnitsToFormat, int totalUnitsFormattedSoFar);
*
* Rev 1.4 Apr 16 2001 13:42:22 oris
* Removed warrnings by changing some of the fields types.
*
* Rev 1.3 Apr 01 2001 07:54:42 oris
* copywrite notice.
* Spelling mistake "changable".
* Compression parameters were changed in order to prevent floating point math.
*
* Rev 1.2 Feb 18 2001 12:03:32 oris
* Added TL_OLD_FORMAT defintion.
*
* Rev 1.1 Feb 13 2001 01:44:40 oris
* Moved the TL_FORMAT_COMPRESSION and TL_FORMAT_FAT defintion from blockdev.h
*
* Rev 1.0 Feb 02 2001 13:57:58 oris
* Initial revision.
