Hello, as the topic titles says, my Kingston microSD 1GB - Made in Japan is dead on March 13, ~ 13:30. I brought it on January 12. And used, within my R4DS, and used the R4DS's microSD reader/writer, and that reader/writer model is the new one wich is not have problems (melting, deading, etc. thats). I confirm that I normally used it intensively. From 7:40AM-14:00PM, played with it, and mostly putted to Sleep Mode. Then, after 14:00PM, played with it sometimes to 20-20:40PM. But nowadays I didn't played that much (from 14:00PM to 21:00PM). But let's hear what happened exactly: In March 13, ~13:20PM I played with Pac-Pix, on the Chapter 6, and it Game Overed ... Time's up. OK, I play with another game. I turned it off, then on, and R4DS is keeps saying LOADING... I tried to turn off again and on, but with no succes to load the menu. OK, I reinsterted the R4DS Card, and my Kingston 1GB microSD (Made in Japan), and turned on the power on my Nintendo DS Lite (EUR, Black). Still, keeps hanging on the LOADING... screen wich is, loads within 1 sec, instatntly. So then, OK, I thinked something corruption or I not know what happened, later in my home, I do about it. When I inserted the microSD to the R4DS's Card Reader/Writer (wich is totally perfectly awesomely cool), and inserted to my PC's USB. My PC is recognized the USB Device (the Reader / Writer), and keeps reading the microSD, tries, tries, with no success, and it's freezing, too! My Windows XP (at that moment) is totally slowed down! But I seen that the Reader/Writer is tried to read it... looks like it's totally unreadable. OK, I removed it, and checked... it's hot. Warmly-hot. The reader/writer, too, and the microSD card, too. So, what am I did wrong? Why is this?... That's it all, discuss about this "The Perfect and The Best microSD card"'s death... It's totally dead.
