Gents,
I had the same issue witzh that bloody SD card thing !>:(
See my thread on http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1261141357
Finally filelogger worked, but stopped recording after reaching a certain limit of characters saved. I need a datalogger with a least 65000 lines each 50 characters in and no system could do that. Now I bought Openlog (http://www.sparkfun.com/commerce/product_info.php?products_id=9530) . I received this with an old firmware level and need to upgrade it. I hope this works as it records the serial port as a dedicated and separated system...
I do not want to demotivate me :-[. If you get it running I would be happy!
