mkexfatfs - create an exFAT file system
SYNOPSIS
mkexfatfs [ -i volume-id ] [ -n volume-name ] [ -p partition-first-sec‐
tor ] [ -s sectors-per-cluster ] [ -V ] device
DESCRIPTION
mkexfatfs creates an exFAT file system on a block device. device is a
special file corresponding to the partition on the device. Note that if
this is an MBR partition then the file system type should be set to
0x07 (NTFS/exFAT) otherwise other operating systems may refuse to mount
the file system.
OPTIONS
Command line options available:
-i volume-id
A 32-bit hexadecimal number. By default a value based on current
time is set.
-n volume-name
Volume name (label), up to 15 characters. By default no label is
set.
-p partition-first-sector
First sector of the partition starting from the beginning of the
whole disk. exFAT super block has a field for this value but in
fact it's optional and does not affect anything. Default is 0.
-s sectors-per-cluster
Number of physical sectors per cluster (cluster is an allocation
unit in exFAT). Must be a power of 2, i.e. 1, 2, 4, 8, etc.
Cluster size can not exceed 32 MB. Default cluster sizes are: 4
KB if volume size is less than 256 MB, 32 KB if volume size is
from 256 MB to 32 GB, 128 KB if volume size is 32 GB or larger.
-V Print version and copyright.
EXIT CODES
Zero is returned on successful creation. Any other code means an error.
