Mirco SD Card Problem

The other day my Micro SD card was doing just fine but just recently my card reader couldn't read my micro sd card and it even went as far as to state that it cannot be used. It is a Kingston Micro SD card with SD card adaptor, it had been working well albeit it didn't read as fast as it should but now it just seems to slow my computer and my device cannot read it. Another problem is that I run my homebrew on it and not even Wii can see it. What is going on? What is wrong with my card?

They do wear out eventually (normally after several years of consistent overwriting).

nice post
