Create a user-space utility that formats block devices with FAT32. Writes all required on-disk structures sequentially: - Boot sector (BPB) with BIOS Parameter Block at sector 0 - FSInfo sector at sector 1 with free cluster count/hint - Backup boot sector at sector 6, backup FSInfo at sector 7 - Two FAT tables with entries 0-2 initialized (media marker, EOC markers, root directory cluster EOC) - Root directory cluster with volume label entry Geometry calculation: - Sectors per cluster chosen based on volume size (1-32) - FAT size computed using Microsoft's formula - Supports volumes from 128 sectors (~64K) upward Usage: mkfs.fat32 hdd1mbr1 14336 [LABEL] The total sector count is required since there is no stat() syscall yet. Users can find it via 'diskpart <dev> list'. Also checked off diskpart in README (committed previously).
This is the ClaudeOS initial ramdisk.
