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.
