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
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.
