Your messy metadata contents seem to be caused by the io errors you metioned. You should still have a valid metadata backup in /etc/lvmconf/ which contains your configuration *before* you added hde1. Please find it using "for f in /etc/lvmconf/*conf; do vgcfgrestore -ll -f /etc/lvmconf/$f;done" and restore it to all PVs which where in the VG before hde1 was added. "vgscan;vgchange -ay" should give you a valid configuration back afterwards. Please rememer to take backups of your data!
