If that happens, I would assume that the disk is dying. Do
not try to fsck it, because it will probably make it worse.
Instead, use "dd if=/dev... of=... conv=noerror,sync" to copy
the disk to a safe place (i.e. other disk of same size or
larger). Then run fsck there.

That's trivial. In /bin/sh syntax:
# cd /home
# awk -F: '$3>999{print $1}' /etc/passwd | xargs mkdir
# for i in *; do chown $i:$i $i; done
That will create home directories for all users whose UID
is greater than 999.
