Make exfat accessible for mac, windows and linux01.03.18

the exfax cluster size may should be 32KB only

if you create the exfat format
use it like

mkexfatfs -i 64KB /dev/sdb1

mkexfatfs — create an exFAT file system
Synopsis

mkexfatfs [ -i volume-id ] [ -n volume-name ] [ -p partition-first-sector ] [ -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.
