My SD card was removed unexpectedly and won't work anywhere no
Try the following: switch off the phone, remove the card, stick it into a windows computer. It will most probably pop up a window with the message that the card is corrupt, and ask: "do you want to format it?" refuse the formatting. Open "your computer", check if the card is visible as removable medium. It likely is, even if the card is corrupt. If it is, copy the data of the card, format it (the card is corrupted after all), and copy the data back. I had that twice now.
