    If your using GO LAUNCHER X / GO X LAUNCHER don't put it in the default. That's my problem for 1 half month I'm suffering from erasures of my files like musics and photos 13-15 times and i try 2- 4 times BACKUP then re-download apps and set launcher as default "IT STILL NOT WORKING" it erased it self again! ,I 1-3 FORMATTED then re-download apps and set launcher as default "IT STILL NOT WORKING" it erased it self again! I RESEARCH IT FOR SO MANY TIMES and any techniques DOESN'T WORK! so i gathered some ideas and solutions on google and when I tried to analyzed anything and I REALIZE something that X LAUNCHER is not the same with the ORIGINAL default/launcher of your phone and it comes out that you shouldn't put in GO LAUNCHER X / GO X LAUNCHER. And I it tried it and it worked. If it doesn't work then maybe try to back up or format and still not work maybe your SD/PHONE has something wrong. HOPE IT HELPS

    Any help would be appreciated. Thanks.

    I have read all the posts and have seen where most have mentioned that it started recently or all of a sudden. I have used the same card since i bought my TBolt on its orig. release date with no problem. I've even been rooted from that time and had to buy another phone cuz it died and used that card in my replacement for several months until a series of recent app updates from the Market. Which one or ones that caused this aren't for certain at moment. After the updates, my phone started displaying unmounted card or damaged card, reformat messages. I bought a new card (thinking the card was bad) and it does the same thing. I am also noticed at times will not maintain a mount for longer than 10-20 min. after a re-seat, revolutionary recovery remount, and power up. Once it unmounts, it wont event remount from the phone storage settings without going through the those steps again. It definitely looks like a bug or a phone issue for sure that is affecting mounting of the card.

    After reading several of the other responses, I simply replaced the sd card and haven't had a problem since. Figure I'd rather replace now and salvage my photos if the card is going to go bad than lose everything.

    Hey guys. I posted this in the roms section, because I thought it might be tied into an issue I'm having with a rom. But I'm starting to believe it's just a coincidence. Throwing it in this thread because it seems to have a lot of knowledgeable sd card people, so here it goes...

    Fresh install done. Now we wait it out. But here's my issue, and I don't think it's rom related, as much as it is a coincidence. Yesterday, I was listening to my music via the stock music player (Poweramp was 1 of the things having issues). The music stopped, and the pop up error on the phone went something like "Card error. Can not read card or it was removed".
    It seems now, the phone. nor my computer will even recognize my micro usb card/ It's an 8 gig scandisk.
    I've had this phone since day 1, and don't remember if that's the card that came with it or if I bought a new one. Anyway, I just plugged in a friends micro usb into my computer. I forgot to look to see what size gb his card was, the computer picked up on it right away. So I know it's not my computer, nor the micro card adapters that I'm using.
    I had some pretty important backups on the card. I can always get my music back, and photo's are dropboxed so who cares. But I'd like to get at my sms and titanium backups.
    Any thoughts?
    I've tried the first 10 things listed on google with no luck. Is there anything I can do if the computer isn't even recognizing there is a removable storage inserted?

    EDIT: It's a samsung micro usb. SO I guess it is the one that came with the phone

    I didn't read all responses but read elsewhere that scanning SD card on your PC is a fix. After encountering this problem in my previous device, I tried it and it worked.

    Actually, that's not how it works. The update gets downloaded to a hidden partition (/cache) on the internal memory, and unless the phone is rooted there's no way you can get to that file.

    If you did have an intact update file (not just any old zip file will work), you could put it on the SD card and boot into Recovery mode and manually load it. The Recovery mode sequence for the S3 is Volume Up + Home + Power, but I have no idea what it is for your phone. I'm sure you could Google it.

    i have the M8 One and have the same issue. Here is what I've heard from talking to people. I'm no expert and I can't say this is 100% accurate but basically...

    The tray the M8 uses to hold the SD card can flex slightly or be jarred and the sd card loses connection for just long enough to cause the mounting/unmounting loop. As the phone ages and is exposed to heat the issues seems to be more common and happen more frequently. The easy fix it to put a few layers of tape on the contact side of the SD card opposite end the actual contacts.

    In light of someone else saying sticking a business card in the tray worked I think there might be some truth to it. I put some tape on mine and been working fine since.

    I've been fighting the same problem with my LG G pad--tried everything including formatting in the pc, running chkdsk, and reinstalling--within 24 hours it had unmounted itself and erased everything on the Sandisk micro. Tried your idea with the calling card and jammed the sd card back in and it's working perfectly for the first time.. Thanks!!

    Lightbulb Re: SD Card Unmounting Itself

    Here is the solution, which worked for me:
    - Turned out that on my new phone, the MicroSD card slot did not fit the card 100%. In other words, it was simply possible to mount the card slightly skewed or non-straight. This should of course not be possible, but it was.
    - I tried mounting (and by mounting, I mean physically mounting it, i.e. pressing the card into the slot with my fingers) it in a couple of different ways, nudging the top to the left, then to the right, etc.
    - On my third attempt, I seemed to have hit the correct spot as the the mounting errors simply disappeared and are now gone completely.

    So my solution was more or less similar to the solution from further up this thread, where a user managed to get it right by inserting a bit of a business card into the slot. Quite a low-tech solution, but I am happy that it works now.

    Just absorbed every opinion and wrong answer on the internet, and I finally stopped at your suggestion.... Take the easy way out. I put a shim of paper between the SD Card, (any brand, even though there is a lot more 'anti-SanDisk than any other, but they are probably 10 times bigger, it seems this problem is not hardware.) and the socket. Slide them both in together, make it click, and try one last time. Mine was stable for 3 years. A 1. Same as \0 I think. Not a single problem. Then, after maybe getting a small amount of moisture or vapor in the case from installing the sink, and recently moving a dozen apps onto the internal SD. It just booted, took forever with the first graphic, powered down, normal start, no SD Card. Read for 3 hours. (Remember how we used to be wizards with Bulletin Boards? UPANET?) Examined the gold contacts on the SD Card with a 30x glass, you can see not all contact scrapes are the same. Some longer, some not as deep as the others, etc, so like you, I chose the most obvious base problem.

    Hope you are still out there... learning stuff. It's fun. A puzzle a day, and sometimes, we have a working phone.

    Reviving am old thread to post my experience and results.
    I had a Samsung 64GB micro SD card in my Galaxy S4. The phone was locking up while on the wall charger. It took me a bit of research to figure out the cause.
    I found this thread, as well as others suggesting using chkdsk on Windows PC to fix the card.
    I backed up the card and performed the check, formatted to exFAT and also formatted the card in the phone. Then copied the backed up contents to the freshly formatted SD card.
    This cured the locking up, but then I got the card removed followed by checking card notifications.
    While backing up the card, I noticed that it was nearly full. Having only a few GBs free space.
    I bought a Samsung 128GB micro SD card, from Amazon, formatted it on the PC and the phone, copied the backed up contents from the 64GB card into the 128GB card and have not had any locking up or card removed notifications, for 2 days.
    The S4 dies recognize all 128 (actually 120) GBs.

    I have been having the same problem. It says my sd card was unexpectedly removed and won't let me open the apps that are on it, however when I go to settings to mount it--it says there that the card is still mounted! I did a factory reset on my phone without the sd card inside it. Worked for a while, like a week or 2, but today it started same problem again. Will it still happen if I format the card? One person in the comments said they did and it didn't work.

    I have had my note 3 for almost 3 years and this problem only started a few months ago. If the issue is the sd card not fitting in right, how come it didn't act up for the longest time?
