mkexfatfs − create an exFAT file system
mkexfatfs [ −i volume-id ] [ −n volume-name ] [ −p partition-first-sector ] [ −s sectors-per-cluster ] [ −V ] device
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.
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.
