I've had my Razr for a little over 1 year. My SD card is from my original phone, a Samsung Fascinate. I've never had issues with the SD card until this week. I received a pop up messages stating "SD Card is unmounted." I have not touched my SD Card since it was put in by the sales rep at Verizon when I bought the phone. All of my pictures, music, and apps were saved to the card. I took it out, and tried it back in my Samsung to find that the card is fine. Everything was there as it should be. I put it back in my Razr and followed the suggestions of a hard shut down, trying to mount the card, once it was removed, the phone shut down, and then put back in, and then started back, the device located my SD Card and it worked. For about 30 seconds and then I received the same pop up "SD Card unmounted."
Is this something I should just take back to the store, or is this something I can troubleshoot on my own. I do not want to reformat the card as I will lose everything on this. Is this a device defect or is this a software update issue?
Some additionally info: no, it does not need to have a system update, and when I go through the file icon in the apps it won't register the card at all.
Suggestions?
