Hey all. Over the past week or so, I've been experiencing a problem where randomly, a message will come up in a random task saying something like "SD Card unmounted unexpectedly, it may be damaged." Anybody else experiencing this? It is the stock SD card and I've made 100% sure it wasn't loose or anything. Think this could just be a bad SD card?

I'm running into the same problem. I've been ignoring it in hopes that it's a software issue that will get resolved whenever a JB ROM is released. Are you running a custom rom? I'm running The Base 0.7.3.
Fyi, I haven't had this problem at all in over two months of use. Ran stock for about a month and The Base rom for the past month.
Thank god other people have had it happen too. It's happened to me a lot BUT.. I had a 32gb class 4 SanDisk in my phone and that was constantly unmounting itself but I put the 16gb that came with my phone and it has yet to do it. Are you guys using a card other than what it came with?
Sent from my LG-E970
It happens to mine quite a bit, probably 7-10 times a day. I'm using a SanDisk 64GB class 10 SD card, formatted as ExFAT. Maybe I'll try switching back to the stock card to see if that has anything to do with it.
I had the same problem and switch out the card and the error stopped. I had the 32GB SanDisk Ultra and with that card it I was getting the random dismounts. I replaced it with the stock card and was working fine. I returned the SanDisk card and got a new one and it seems to be fine for about 5 days now.
What file formats are you using. My 64 GB is formatted as Fat32 and I've never had this issue. I also think that the included SD Card was pre-formatted to Fat32 which may be the reason it stopped when you switched back to it.
There you go... I've always used the stock sd card. Are you guys losing data when this happens?
This used to happen to me on my 64GB Sandisk Class 10 formatted with exFAT. I fixed it by running CHKDSK with both options checked in Windows 7. Hasn't happened since. It said it didn't detect any errors but it did something lol.
I don't believe I've lost any data. All of the songs I put on the SD card still play. I may try repairing it or using the SD card from my inspire, which may prove to be worse since I think it's only a class 4. I'll post once I figure something out.
One last thing was I tried doing a non-quick format of the card and after that my phone would not recognize that card at all until i exchanged it for a new one.
I generally don't recommend letting Windows GUI format a flash card. Google around for windows make clean, windows command line clean and format. That's your ticket right there.

Hi have a Lexar class 10 sd card that I purchased ~6 months ago for my Evo. Had issues with other cards, and this was the one card that was rock-solid for me on the EVO.
This morning, my Photon started acting very laggy. Programs would refuse to launch, and it was generally having issues.. Upon rebooting, my sd card was gone..
In windows, the sd card has a partition, but requires formatting now this card was rock solid for me in the EVO, so concerned that it died within 24 hours of having it in the photon

No issue here from my 2 year old 8gig and it has been in since Sunday.

I had problems with the same microsd card, and wound up having to RMA it. I've heard of others who have had similar failure issues. I'm highly skeptical that the Photon actively caused it, as opposed to just poor coincidental timing.

While I do not know about the wintec card, but the Lexar one has been known to do this. There are a few xda threads scattered throughout the forum as well as over in Amazon that have mentioned the card as well as a few others that work for a while and then poof they act like this. it seems to be common with 32GB class 10. Another one that has issues is Patriot (see xda thread) but at least Patriot has acknowledge the issue.

FYI. Estrong's File Explorer does not work correctly on the Photon. I have a 16gb sd card and Estrong's File Explorer will only detect 8gb of it. Use the factory installed file manager instead. I thought my card got wiped when I first got my Photon but that was the culprit. Windows showed all my files still intact.

All I know is that when in Estrong's File explorer I can switch between sdcard and phone memory and it only sees 8gb of my 16gb card. Im very familiar with Estrong's File Explorer. I've been using it quite a while. Not sure what else it could be because the stock file manager on the Photon sees all 16gb of my memory card.
If you're not seeing internal phone memory, internal SD card, and external SD card) three separate locations) then you're just not accessing the SD card correctly.

I have a microSD card in my phone and I don't have any problems with it not recognizing it. Maybe you have a bad card. Make sure the card works or the files you have are corrupted.
I a Sprint Product Ambassador and would love to look into this further to help. I need to narrow it down to any specfics I can get. So...
To anyone having the issue:
What was the brand? (i.e. Sandisk, Lexar)
Size of the card?
Any other information that may be pertinent.
One thing I noticed about file explorers in general, esfile explorer, astro, etc, they detect the internal memory as the sd card and not your actual sd card.
Also, I reformatted my sd card from my 3vo after backing it up, because in general when you put an old drive, or something similar into a new computer it may handle it differently than your previous computer did, in our case our phones. Now this may not be the case, but this is just my thoughts on how it may work. Which could in turn bork your card. Should be okay after a reformat.

Just had my SDcard become corrupted while in phone. Showed "Damaged SD Card" warning in Notification bar. I then had to reformat the card. It's working just fine now. I think perhaps some data while writing to card becomes corrupt.
Others report if you have similar issues.
My card is a 16GB Class 10 Patriot (I think)
Hi ,
My External SD card on galaxy s3 i9300 international version .... shows up on the notifation bar that Sd card removed unexpectedly.... this happens evry 10 mins or 15 mins....
Help appriciated
Have got the exact same issue and drains the battery quicker as it has to keep on rescanning the SD card...I have reformatted the card and it still doesn't help...did not have this issue until last week and don't know what happened for the SD card to keep on being removed every 10-15mins..I have realized that every time I wake the phone up I see the card icon in the status bar for a second.. Sadly I have read that this is a common issue and it eventually can fry the card and make it useless so I have decided to remove it and not use a SD card(main reason I got the phone was for this reason)...since then my battery has been amazing as the media scanner is not constantly running..so far no one seems to have a reason why this suddenly happens as I have not had an issue since I got the s3 which was over 6 months ago and out of nowhere this issue occured..I hope that this may be an software issue which can be fixed in the future or hopefully someone in xda can either find out whats the issue or find a fix till then I will keep my 32 GB sandisk card safe.

Do you use a Sandisk 32GB card by any chance?
I had these same issues, which went away once I changed to samsung cards.
If you can, return the card for replacement, as cards made after december 2012 dont have this issue anymore.

Interesting, i have exactly the same issue since january 1th. It worked for about a month without any problems (bought it late november).
Now this is killing me how it behaves every 5min. I have reset the phone, updated the phone, formatted the sd-card.. nothing helps.
So if i return my sandisk 32gb, should i ask for a new sandisk or go with the samsung?

Had the same issue with my S3.
Turned out that the SD card was dying, this caused it to be unmounted by itself and then mounted again (sometimes showing notification “sd card removed unexpectedly”), hence triggering the media scanning process.
I created an application to monitor how many times the SD card was removed, and turned out to be unmounted every ~3 mins!!!
I then bought a new Transcend 32GB Class 10 card, and until now, this never happens, no reports from the application whatsoever, and no media process eating my battery.
I just published this app in the play store now, this is the link:

I've seen my 64Gb Sandisk card auto unmount and remount itself a couple of times today, have seen it once before. Again was caining the battery on the phone with the media process rescanning it.
Thanks for the app I've installed it to monitor this from now on, to see if its potentially a faulty card.

This app is really great, proves the issue. Like others, I have this problem with a Sandisk Ultra 32gb. I tried popping in an old 4gb card (forget the manufacturer) and had no issues.
Saw somebody else suggesting that the Franco kernel fixed this issue, and sure enough it seemed to have cured it for me for a few weeks, but it's just started again today - your app showed unmounts/ejects happening every couple of minutes, so I've now submitted a request to Sandisk to return the card.
I was putting music on my P769 and when I tried playing the new music, it would say it was a unsuppoorted format, it wasnt, it was a mp3. I tried other songs that I knew that would play and none of them worked. I then restarted th app and a song would play but once I tried another song it would do the unsupported format message again. I then restarted the phone, the phone then gave me the message in the notification area saying "Blank SD Card or Unsupported file system." I then tried mounting it, with no avail, it still wont work. I then factory reseted my phone and formated the SD card, and still that same message comes up. Also, before(and after) the restart, I would try to unlock the phone by pressing the power button the screen would start t turn on but automatically shut off, or it would go to a "snow" screen, but grey. Please help I need the SD card because of this phone's microscopic amount of memory!
I forgot to add that I tried the SD card in another phone and I had the same issue...
Get a new SD card. I had similar problems with my 32gb card when I got the phone. Bought a new class 10 16gb card and it works flawlessly.

I got the 32gb card for like $9 on black Friday around the same time I got the phone. It was flaky right from the start, but worked in my laptops card reader. Made me think it was something with the phone. It eventually stopped working in my card reader as well. Pickup a good class 10 card and everything should be fine.

So just so we're clear, can you put the card in an SD card reader and transfer files to it from a PC? Can you play files off of it through an SD card reader to a PC (or another non-Android device)?
I'm far from an expert, but maybe try breaking the card into separate partitions with something like MiniTool Partition Wizard. The card might be formatted in a way that the phone isn't familiar with. There are a few other threads on the forums that can help suggest what kind of partition would be best for your needs.
I have a 32GB SD card, and it took me a long time of messing with this damn phone to get it to do what I wanted. Card would disappear, messages about "insufficient storage", media scanner freezing up, on and on. This phone has been one huge pain in the ass. Right now I am just using a remount script to swap my internal and external, but so far so good.
Ok guys after extensive searching...I'm having the exact same issues. I did more investigating myself. When I removed the 32gb card from the port I noticed the pins in said port were messed up, the last two looked disconnected. After fooling with it for a min I decided to use the card on my tablet to get files from it, unfortunately the tablet didn't recognize the card at all. I'm thinking my phone corrupted the sd card somehow. I have yet to try another card in my phone for fear of messing another up. I'm going to try to insert the original 32gb card and have it reformat like it's asking and see how it goes. If that fails I'm gonna try a lil 2gb card in it. Also, I've contacted LG and am awaiting a return call for a warranty repair because it looks defective, I haven't dropped the phone recently, and just bought the phone in March from Best Buy... I'll keep y'all updated on my progress and wish me luck lol!

Alright here's my update, I have the SanDisk Ultra 16gb micro SD HC I u (red and grey), I think my sd card is going out as well, but I'm wondering if there might be more to the problem. Yesterday i took out the card and I placed it in my computer to move some file. It didn't pop up at first, I wiped it and place it back in the PC and it started working. Once done, i place it back in my cell and it was working fine. I went into CWM to flash a backup. I was doing some testing so I flashed two different backups. So today i noticed that the Sd card it not mounting, but when I'm in clockworkmod it is working fine I have rebooted and checked several times, it's mounting and operating on my PC & CWM but not when the phone is on. I'm thinking CWM might have something to do with it, not sure (might be a system restore). I was going from 4.0(ice) to 4.1(jelly) & back to 4.0. I'm currently restoring one of my jelly bean backups to see if the problem is solved.
Update:
my L9 is back on Jelly Bean and the SD card is working, it might have been a corrupted backup (or something went wrong with cwm). Md5 is good, but it's not as accurate as SHA-256 checksum. Y'all might want to check if your SD card is popping up on CWM.
Good info.
this is a problem that occurs when we upgraded from ICS to JB. once I upgraded my d card would not work. So I took it out and formatted it on the computer. Then I partitioned it with a program I have and it worked. JB and ICS having trouble with the sd card. If you go back to ics then don't reformat our you work have tip reformat when you flash jb.

I have a Sandisk Ultra class 10 64gb external SD card which has worked well since I purchased the phone (several months ago). Recently however, I've been running into issues where the ROMs I've tried won't recognize it (Beans, Carbon, Liquid). The strange part is that TWRP recognizes it without a problem (I've flashed from it several times). I've tried both nandroid and clean flashes. I've done a a battery pull and booted the phone without the card mounted. When I insert the card, I get the typical "Preparing SD card" message, which doesn't seem to go away.
Anyone have any suggestions on how I could try and fix it (other than hopefully buying a new card)? Thanks.
EDIT: Ignore. Formatted the card and that seems to have fixed it for now.

I have the same card but the 32gb. On Amazon alot of people complained about the card not functioning after 6 months of use. So I opted for the 32gb version which had the same complaint, just not as abundant.

I see you've fixed the issue, just in case you didn't already know though AOSP ROMs can only use the card when its formatted as fat32. TW ROMs can use the card formatted as exfat. Going back and forth between TW and AOSP may have corrupted your card if it wasn't formatted as fat32 when you went to AOSP.

It may just be that the card died, I have several 64 GB class 10 micros and have no issues, from what I hear though the class 10 is the worst and if you can get the original 64GB that wasn't a class 10 these issues aren't there.

I'm guessing something got corrupt somehow, or the card is on its way out. Once I reformatted it, it started to work again.
So my MicroSD card (32GB SanDisk Class 10 Red/Grey) has been acting weird lately (since I upgraded from ICS to JB). Not my phone automatically unmounts the card from time to time and I don't know why. I have trying formatting from Windows and from the phone, with FAT32 and ExFat. And I don't want to wipe my phone or install any other ROM or similar stuff.
I will try another card, but is there something I can do to prevent this?
This has nothing to do with your ROM or your phone, it's your SD card itself which is causing this problem. Just try another SD card and I'm sure the problem is solved.

Yup, S3 has some issues with SD cards (see http://forum.xda-developers.com/showthread.php?t=1906058&highlight=sd+card+killer). Allready killed one of mine too, couldn't do anything with it. No device even recognized it anymore.
I insist, maybe it's my phone because it happened right after the upgrade, maybe something in the ROM, OS, kernel, or something... so I guess it's a lottery... I'm trying another card now...
