FAT32 filesystem formatter

Implementations§

Source§

impl Fat32Formatter

Source

pub fn format<B: BlockIo>( block_io: &mut B, partition_start_lba: u64, partition_sectors: u64, volume_label: &str, ) -> DiskResult<Fat32Info>

Format a partition as FAT32

Creates minimal FAT32 with:

  • Boot sector at LBA 0
  • FSInfo at LBA 1
  • Backup boot sector at LBA 6
  • Two FAT tables starting at LBA 32
  • Root directory at data start
Source

fn optimal_cluster_size(total_sectors: u32) -> u8

Calculate optimal cluster size for partition

Source

fn calculate_fat_size(total_sectors: u32, reserved: u16, spc: u8) -> u32

Calculate FAT size in sectors

Source

fn build_boot_sector( total_sectors: u32, fat_size: u32, spc: u8, hidden_sectors: u32, label: &str, ) -> [u8; 512]

Build FAT32 boot sector

Source

fn build_fsinfo(free_clusters: u32) -> [u8; 512]

Build FSInfo sector
