heh, thats who I bought my sd card from as well. Well I did like you said and formatted using the usb adapter he sent with the card, this was on wenesday and I have loaded it up with gps maps, music and all my programs. I am using like 2.8 gigs right now. It has lasted for 4 days now, we will see if it stays that way as before by a day everything on it was wiped out.
