i just got the dstt last i triend going through the in the instructions but it wont recognized the sd with the usb. and when i try to use it with the sd adapter it tries to format the card and it says it wont let me. i go to disk management it says its undreadle. So i tried taking some pics in my fone with it and tested the memory and it worked fine .the question is it the memory card or the reader and adapter.
try this, download panasonic sd formatter here http://panasonic.jp/support/global/cs/sd/download/sd_formatter.html and see if you can format your sd card. cant ruled out the dstt untill you actually tried it out with a micro sd card with firmware installed.
