I have an 8gb Transccend SDHC card which worked fine (well the palm still had reboots freezes etc...) until after the v1.10 sprint upgrade... now (this has happend twice) I have moved a file from palm internal memory to card (once with filez and once with camera application) and the card has lost all its data. i.e. writing from the internal memory to card causes some kind of corruption.

-data still not seen by external cardreader from my mac (card seen with folders dcim, palm, launcher and albums.db appearing)
-do I need to reformat the card in fat32 x 32? If so how to do this by mac?
-tried to reformat with palm and just stalled out.

thank you
