Hey, I have a 16 GB Sandisk microsd card that I was using in my Blackberry. I didn't have a micro usb cable at the time so I was placing music onto the microsd card via an usb adapter. Apparently, I didn't eject the disk safely and it got corrupted. When I plug the adapter into the usb port I get a popup stating "The disk you inserted was not readable by this computer." with the option to Initialize, Ignore or Eject. The disk shows up as a 32.1 MB generic mass storage device. Disk Utility, my Blackberry, and Win XP can't reformat the card. How do I repair the card so that it shows up as 16 GB. Is that even possible or is it a complete loss?
