We use many cards, the card's female sockets wear well before published design failure; where one or more pins fail to make contact. The failure in your card is in initialization, usually the ground pin I described above, which is not making contact. To verify, insert the card holding it in tightly and at the same time pushing down on the card. If you are then initializing -- do the fix. Just find a machbook cover, fold it in half, cut to a 3/4" x 3/4" square and tape it to the top of the card as it lies flat on a table. Then insert both cover and card, one or more times at first, until the pin/socket contact problem is gone. I wet through months of playing with card initialization failures before using this temporary fix; only later to tear them apart when I had some time and soldier a very thin coat of high quality solder to the failing male pin (to increase its thickness when inserted into the female socket of the card). Problem then permanently solved. Your choice...

Wow, that really worked! I never realized how much space there is between the top of the card and the edgce of the CF slot. I pushed down on the card while inserting it and it worked! Repeatedly! I used to try to push the card in really hard, now I realize I just need to push down on it a little. Great find and thank you so much for sharing!
