i formated my 2gb sd card today on treo 680 using Card info, now it can't be read when I insert it into my card reader which connected to a pc. I tired to use my treo 750 to format the card, but the treo 750 can't read it too. But I have been using this card for 3 weeks on my treo 750 and just began to use it on treo 680 today. Now it can only be read by Treo 680.

I gues it must be that the treo 680 formated the disk using some kind of data format that is not reconizable by windows, what can I do now? is there any software on palm that can let me format the disk again into FAT?
