The diode trick will not work with all SD cards.
The only sure solution is to use appropriate level shifters with correct levels and timing.
The Arduino company, Adafruit, Sparkfun and several other companies produce excellent products for using SD cards with 5V Arduinos.
I am the author of SdFat which is also the base for the official Arduino library. Marginal solutions that use resistors, diodes and other tricks cause problems for many users. I suspect this post will add to my email load.
