| 30 | .SH DESCRIPTION |
| 31 | .B mkexfatfs |
| 32 | creates an exFAT file system on a block device. |
| 33 | .I device |
| Matt Mower | 09ef1e4 | 2015-12-13 11:29:45 -0600 | [diff] [blame] | 34 | is a special file corresponding to the partition on the device. Note that if |
| 35 | this is an MBR partition then the file system type should be set to 0x07 |
| 36 | (NTFS/exFAT) otherwise other operating systems may refuse to mount the |
| 37 | file system. |

| 40 | Command line options available: |
| 41 | .TP |
| 42 | .BI \-i " volume-id" |
| 43 | A 32-bit hexadecimal number. By default a value based on current time is set. |
| 44 | .TP |
| 45 | .BI \-n " volume-name" |
| 46 | Volume name (label), up to 15 characters. By default no label is set. |
| 47 | .TP |
| 48 | .BI \-p " partition-first-sector" |
| 49 | First sector of the partition starting from the beginning of the whole disk. |
| 50 | exFAT super block has a field for this value but in fact it's optional and |
| 51 | does not affect anything. Default is 0. |
| 52 | .TP |
| 53 | .BI \-s " sectors-per-cluster" |
| 54 | Number of physical sectors per cluster (cluster is an allocation unit in |
| 55 | exFAT). Must be a power of 2, i.e. 1, 2, 4, 8, etc. Cluster size can not |
| 56 | exceed 32 MB. Default cluster sizes are: |
| 57 | 4 KB if volume size is less than 256 MB, |
| 58 | 32 KB if volume size is from 256 MB to 32 GB, |
| 59 | 128 KB if volume size is 32 GB or larger. |
