This has nothing to do with file systems. This is a simple application task
where access to the drive is obtained with CreateFile.

Form the FAT(32) boot sector manually and write it to sector 0 of the drive using WriteFile.

Also write empty FAT and root directory.

Thanks for reply.

But how to format the USB pen drive programatically.

Thanks,

Windows quick format is exactly what I have described - just quickly write the empty filesystem.

Full format has one more long step - IOCTL_DISK_VERIFY for all sectors on the disk.

You might want to take a look at the ‘ramdisk’ driver in the wdk
(src/storage/ramdisk).

In particular, ‘RamDiskFormatDisk()’ in ‘ramdisk.c.’

Good luck,
