I got my r4 card today and everything was going smoothly. I put the sd card in the card reader and plug it into the laptop no problem. I put the games on the card and then removed it safely from my computer. I plugged in the r4 card and before I booted it up I remembered I forgot to put all the Wood kernel stuff in it. So I removed the sd card from the r4 card and plug it back into the SD reader. However this time my computer does not even recognize it as a removeable device. One time I did somehow manage to get it to be recognized but it acted as if my micro sd card was not plugged into it. Every time I plug it into my computer though I hear that sound the computer makes when you plug in a usb device. All the drivers are updated on it. I looked around on the forum and saw that these readers are not very reliable however these posts were stamped with dates in 2007 and such. I was just wondering if you think I pulled the trigger to fast by heading over to amazon and buying an new micro sd card reader. I also bought another 2gb micro sd card just to make sure. When I plug in the r4 card without the sd card a message appears and says 'Cant find the sd/tf card." With the sd card in it says sd/tf card error'. I expect the later is because I do not have wood kernel.
