    When I got my phone, I inserted and formatted my SD card from my old phone.

    Everything was fine and dandy. I loaded it with music. I just got back from a trip to New York and have some pictures on there that I really want.

    So earlier this week, I had my phone charging on my laptop through the USB cable. I was not browsing any files on the phone. I was simply charging.

    When I unplugged it I got some error message about the device being suddenly ejected. Ever since, the SD card is not recognized. It used to say no SD card mounted.

    So I called Sprint tech support and they suggested putting it back in my old phone to retrieve the files and save it on my laptop. It didn't work, it says something about unsupported system files.

    Then I put it back in the S3 and now I'm getting the same message. It's asking to format the card but that would mean losing all my valuable pictures on the card.

    How can I get my photos????

    Looks like the file system is borked and format is the only way.

    You MAY be able to get data back, with data recovery programmes, but it's not likely you'll get much back.

    Essentially the file system is a reference to the actual location of the card on the card. Formatting the file system replaces the reference to that location but not removing the actual file. It simply gets overwritten by new files in the future.

    What these data recovery programmes do is locate these files with no reference and make them retrievable. Obviously the more activity on the card, the less chance of recovering them

    You can try handy recovery.


    I recommend using your old phone if it can mount as usb mass storage.

    In regards to the future, I highly recommend this:


    You just need to be careful that you know what you're foing. The bad reviews are people who didnt.

    I sync my internal and external SD card to my NAS every night.

    I had this happen numerous times on my S2. I have had success copying all the contents to my pc and then reformatting the sd card and copying everything back. When sprint said put the sd in the phone and copy the files, did they suggest you put the sd in your pc and copy the files manually? give that a try...

    Btw, when you are copying to your pc, the file causing the corruption won't copy, just skip it

    One thing you can try is to get an SD card adapter that will allow you to plug the card into your desktop computer. the Desktop computer will mount the card as a hard drive. You can then see if the desktop computer can access the files. you also have access to any file recovery programs on your desktop computer to try to get the files off of it.

    After you do get the files off I would toss the card and not trust it anymore. new cards are fairly cheap.

    I finally got around to putting the card into an adapter when I ordered a new 32 gb card. When I plug it into my laptop, it still asks me to format it. Is there anyway to bypass this?

    It sounds to me like the SD card was erased somehow. Can you insert it into your computer then go to start, computer, then right click the SD card and go to propeties and tell me how much space it says that you have on the card.

    If it isn't formatted, it may not show. Using Disk Administrator will show whether it has a partition on it or not.

    Your best bet is to try the aforementioned recovery program; you extract the RAR file just like a zip file (7zip is a good program for that).

    If you're willing to spend some money, you can try what I did -- but I'll tell you in advance, it didn't do much good.

    It appears that the SG3 has a problem in that it overheats and then trashes the filesystem on the SD card. IT did that to me, and from what I read in these forums, it has done that to others as well.

    When that happens, the PC can't read the filesystem on the SD card and prompts you to reformat it.

    I got RecoverMyFiles and used it to scan the SD card. IT found LOTS and LOTS of files -- but nearly all of them were now zero-length files, meaning, they were essentially empty.

    You can download a trial version from Runtime Software and at least see what it finds on your SD card.
