On a real computer, it might have helped to re-insert the disk at that moment? It may also depend on the kernel version: After the FORMAT loop, the disk does not yet contain a filesystem, but the error message happens AFTER writing the boot sector, BEFORE the FAT and root directory get written, according to the messages... A workaround would be to write the FAT and root directory using raw BIOS I/O instead of already switching to DOS I/O after the boot sector update, any comments from kernel experts? As far as I remember, using less raw BIOS I/O is generally more "friendly".
