Since the FAT and root directory reside in low
sector numbers, this may improve
performance. However, this option has an
overhead in TrueFFS memory requirements.
For more details, see Performance
Considerations, later in this manual.
The default is 64 KBytes. In principle, it is
possible to specify a size that will span the
entire medium, if the memory required to
handle this is available.
/SIZE:size The size of the Flash medium to be formatted
(including the boot-image). By default the
entire medium is formatted by TFORMAT.
This option may be used to limit the formatted
size to a smaller size.
/LABEL:label A string to be used as the DOS label of the
formatted medium.
/DOSVER:dos-major-version Format for a target system running the
specified DOS version. The default is the
current DOS version (the one on which
TFORMAT is executed). E.g. /DOSVER:3
formats for DOS 3.x. Valid values are 1 to 6.
/SPARE:n Leave n Flash erase units as spare units for
garbage collection. The default is 1. At least
one unit should be specified for the Flash
medium to operate as a true read-write device.
More than one spare unit may be specified to
format media that have bad Flash units. In
such a case the number of spare units should
exceed the number of bad units by at least 1. It
is also possible to specify more than one spare
unit in anticipation of Flash units becoming
bad in the future.
A value of 0 spare units may be specified to
create a WORM (Write-Once-Read-Many)
disk. When formatting with this option, the
Flash medium can be written once only, after
