If I understand rightly, you created or reconfigured a cryptsetup
volume (hdd500_crypt) but it's not listed in /etc/crypttab.  The
initramfs should still work as it only needs to mount / and /usr, but
you probably couldn't boot all the way to multi-user mode without
/home.

Is hdd500_crypt listed in /etc/crypttab?  If you add an entry for it
and re-run "update-initramfs -u", does it complete successfully without
warnings?
