    Default SD Card Unexpectedly Removed

    Hi,

    I updated my Galaxy Note N7000 with Jelly Bean 4.1.2 on 21st March, 2013.
    My Memory card is Sandisk 32GB Class 4.

    After my update I found my memory card continuously unmounting and mounting due to which my battery is draining away very fast.
    If my phone is been charged or if I m using it, then nothing happens, but if it gets into idle mode then after very 2-3 mins memory card will unmount and mount.
    This problem was not there before updating.

    I tried removing memory card and re-inserted the same and restarted several times, but didn't worked.

    Plz help me solve this problem.
    Is it update issue or card issue or some app issue ??


    Thanks

    Take a look at the thread here: [Q] sd card unmount unexpectedly - xda-developers

    Bottom line, you may need to get a new card, and not the same one either.

    1) Insert the micro sd card in the computer
    2) Go to DCIM folder
    3) Delete MISC folder

    well there are .dropbox.device file in the MISC folder and i guess its messed up the phone and the memory
    try delete it and see whats happen

    I read somewhere recently where problems had been found with Sandisk 32 & 64Gb memory cards. The problem was with the super high speed class 6 which I was using in HTC Sensation. The card kept unmounting. This has now been installed in GN2 & it seems fine.

    Hi addyco,

    But before JB update, my memory card was working perfectly fine.
    Its not that card is corrupt as its working perfectly fine with other devices.

    I had the same problem with a Sandisk 32gb card in my S3 . Put in a Acer tablet and it works fine, put a spare Sandisk 8gb card in my S3 and its fine. So based on this its either a JB issue or a Sandisk issue

    Hi all,

    I finally came to conclusion that its because of memory card kept in phone while JB getting updated.
    So guys, next time just remove memory card while update any OS.

    I just replaced my memory card with other 32 gb sandisk and now its working fine.

    Hey all,
    I am having the same issue. The card may or may not be read by my laptop either, it's about 50/50. I was able to copy all the data off, thankfully.

    I read somewhere that this may be caused because the SD card was connected while rooting the phone. I don't know how true that is, but I gave it a shot. I re-rooted my phone with the card removed. Then, I formatted the card (FAT32, 32KB) in my laptop. I did a full format, not a quick one. I did NOT format the card after I put it back in my phone. Then, I copied all the content back to the card (card in phone).

    it's been ok for a few days now. Could this have been helpful? Is it possible having it connected while rooting is causing an issue? I'll update here if it starts acting up again.

    Hi there!

    -------------------

    It started on my Galaxy S2, which had just ejected my Kingston 32GB SD Card one day, the card survived until I moved on the Galaxy S3.the same error ..
    The SD Card then was definitely destroyed.I inserted and a new SanDisk 32GB and after a week, the same error .. now after several days on the Galaxy S4 the same problem.

    According to my knowledge, this problem can have several causes. Maybe the SD card is driven by a high voltage on the SD Card slot or the SD Card is simply not robust enough for the hardware. Maybe both playing together and the operating system has problems.
    whatever...

    I've programmed a small app "SD Fix Tool" to prevent this annoying error. Also the mediascanner can enabled and disabled to save battery.

    To prevent the SD card error, there are two services that can be activated and deactivated. However, these functions are only experimental and not prevent all errors!!

    On my Galaxy S3, the SD card was ejected 700 times in 2 days.
    After activation, there was about 80 times.
    The function does not prevent all errors!

    Also, the message comes after the activation screen not as often.

    This app need ROOT access for activation and deactivation
    the media scanner!

    The media scanner scans the internal and external SD card.
    The path to the external SD card is "/ mnt / extSdCard /".
    You can set other paths in settings.


    App tested on galaxys3 and s4

    Same problem with note 2. Does the download only work for the s3 and 4?

    My micro sd card was doing that to but when I transffered all the pictures off the sd card and onto my phone, the sd card stopped unexpectedly removing itself. I don't know if that will help or not though.
