After a pair of spoiled SD Cards, I've started to investigate what's happening with the SD cards and the Raspberry PI. Overlocking? Too many reads and writes?? Bad batchs?? At the current point of my investigation (2013-08-24) it seems that nobody knows, or at least all these problems can cause a SD corruption.

I've started this page to collect all my investigations and further directions.

• April 2013: a well docummented case in raspberrypi.org.
• March 2013: a technique to avoid data corruption by making regular checks on the sd card

Test with a multimeter the power source I am using: is the best possible?? I've detected that many charges of mobile phones have notorious variances in their voltage. Is this the case?? If it is, I will use a regulated power source (those that keep the voltage regardless of the consumption).
