Just updraded to this blackberry from a regular phone. Took my microSD from old phone, put it in BBerry...says there's a disk error. Keep in mind, this works fine on my other phone. There are only photos on this card, nothing else.
That's because the card was formatted for that particular phone. Save all the pictures you want to save on your PC. Reinsert the card into your BlackBerry. Go to "options"-"media card"-hit the BB function key (to the left of the trackball) and select format. It should work after that.
