Phone is a Motorola Droid. I switched back to my Blackberry for a little bit and tried to use my 16gb SD card from my Droid in the BB. It didn't work and after some research I found out the BB couldn't support a 16 gig card. Since then I've switched back to the Droid and now the phone will not read the card whatsoever. It won't let me mount or format the card. Those options are blanked out. The phone does read the 2gig card out of my GF's Incredible so something is wrong with the stock 16gig card. I believe the card is now formatted for a BB but I don't know how to reformat it to the Droid if it won't even acknowledge that the card is in the phone. Any help is appreciated.
