Chris,
What I read on that thread, he insert in the right direction same as others but the CF male sockets damaged the row of pin of his D70, if you insert the card in with the wrong direction then:
1/ hard to push it in.
2/ Once it's in by force, you can't get the CF card out and had to use the plier with the point to pull the CF out with force.
3/ some CF cards might have the slider not well correctly allignment, therefore when you insert it the row of holes did not get in straight and bent the pin. Same as insert the CPU into the socket of the maninboard.
4/ I have a customer (Govt. Dept) rang me last week about their camera did not register any available space on the CF, after 5 minutes, I found out they inserted the CF card wrong way and can't remove it, it's now in Maxwell workshop. Big bills to come
