I have a 4GB A Data Micro SD that I purchased from Newegg. I had been working fine until today when all of the files on it vanished. I tried to read it using the adapter in 2 different PC card readers, but it wasn't recognized at all (it wasn't the adapter at fault as that worked when I used the 512MB card that came with the phone).

I downloaded StorageTools to try to reformat the card, but it doesn't show any cards installed. In fact, the settings, memory, also shows no card installed. However, I can copy files to and from the card using ActiveSync and can run the programs from it.

Obviously I am afraid to put everything back on it because there is clearly some essential problem since even the system's memory utility says no card is installed!

BTW this is a Sprint Touch.

Any thoughts as to how I should proceed? Thanks.
