Ext sdcard corruption

So I don't know what's happening but I have a 32gb class 10 micro sd card. And once a week it just goes corrupt and my files are all corrupt. It's seriously getting on my nerves and I don't know what to do. I I've formatted it in the phone and in a pc and it doesn't matter it still happens.

They don't last forever. Have you used that card a lot?

Any ideas? It will just abruptly stop saving pictures to my ext sdcard and when I use root explorer to see why it has changed from read/write to read/only.

Sounds like the card may just be faulty?
I have had one incident with my current SD card recently where it wiped itself but fortunately it hasn't happened again. I have a 32 GB Class 10 also. I have read of other experiences with QC issues with lesser known brands like "Patriot" (my current) or "PNY". I think for my next one I'll spend the extra dough and go Samsung. I hear those are built like tanks

SanDisk are the best. I have a 64GB class 10 microSDXC UHS-1 in mine.

It could be the card itself. Why not try another card and see if it happens on other cards.

Damnit! Not good news for me. I hate that the internal memory is all one partition. This is ridiculous.

Help needed!!! Sd card error.

My phone was charging this morning. And then out of the sudden, I look at it and have this notification.(see pics below). I click on it and a box comes up asking me to reformat my card. I have too many pics on that card that I would hate to lose. By the way is a SanDisk Ultra class 10 32GB. Any thoughts or possible fix?

SD Card broken?

Dear all,
A few days ago I got my micro sd card from my Samsung s3 taken without disabling them. Since it is no longer recognized by the phone and not the PC. If I plug in the PC takes a long time until I can read the properties. This shows 0Byte. Formatting is not possible => no medium available!
If the card is defective? Or I can somehow bring to life?

Having same issue here. My second card just did it again after a month. Using a sandisk 32gb. I couldn't find a way to fix it.

If you can't format it, and if your computer can't read it there's no way your phone is going to be able to. You took it out without disabling it in your phone first? Bad mistake that feature is there for a reason
Sounds like you may need a new SD card. I have a 32gb sandisk and mine works perfectly :angel::victory::silly:

I didn't remove mine. Mine was in phone when it just stopped working both times.

I am having a similar problem I never removed SD after initial install and starting a few days ago it constantly says SD has unexpectedly been removed and then it mounts and unmounts on its own I tried reformatting it and sometimes it works for a while but eventually goes back to do that.

My SanDisk 32gb card also did this. I've had bad luck with the 32gb card's. I've had great luck with my SanDisk 64gb ultra card, and 16gb card's.

Is everyone had this issue?? Because I had this issue too with my 32 gb card!!
Sent from my SPH-L710 using Tapatalk 2

Had the same issue with my S3.
Turned out that the SD card was dying (the card brand is Team Group), 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 (made in Korea), 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:
https://play.google.com/store/apps/details?id=com.sdcardmonitor

My mom's OG Epic just crapped out.. 16GB Lexar (i think it was) worked fine.... all of a sudden "Damaged SD Card" on top of screen, Put in computer, no dice... Finally got PC to format it, Worked fine in there, Phone still wouldn't read (Formatted different file types each time) tossed in an old 2Gb.. Worked like a true pilsner.. So looks like my computer has 16GB of extra storage now. LOL

Sd card problem solved

So I have had the sdcard problem for the last month or so, and think I have resolved it. Under settings, developer options, click on and check protect sdcard, reboot and the problem should be solved.

People were having sd card "removed " problems.
Emiliano, did you read that link I posted in the other thread ? Checking that box might make some apps FC.

Going to give this a shot. I saw the one about a loose connection also but was traveling for the holidays and hadn't had a chance to take my notes apart. Will report back on the results.

I resolved my sd card by using a card other than a sandisk 32g ultra. I went to a samsung card and now it works as it should.

Yeah predation, but tried it anyways, thanks.

So far no issues. I didn't want to spend more money on a Samsung card when I already had a perfectly good SanDisk. Now if you are buying a new card to use in your note, I skip the headache and don't get a SanDisk.

I was using power amp to listen to the music on my sdcard. When I unlocked the phone after about one hour it did the missing sdcard thing 1 time. Have not been able to reproduce since power amp was closed.

So the problem has slowly crept back in. The next step is to feed Samsung some more cash for a new sdcard. Almost as bad as Apple.

Maybe you should edit the title of the thread to indicate that the problem isn't solved...

I had this issue on my Samsung Epic 4g. I found it to be an issue with having too many apps running from the SD card.
I went through several sd cards, reformatted countless times, to no avail. Only after taking a bunch of apps off my card, and using primarily the internal memory of the phone did it finally stop doing the "sd unexpected removed" error. It has been almost 4 months of daily use without a single hiccup since.
Try it on your phone and hopefully it can resolve your particular problems.

I swapped my 32gb SanDisk ultra with my wife's 32gb Kensington class 4 yesterday. Like everyone else I have stopped having the problem. It does just seem to be the SanDisk ultra that has the problem with the note 2.

My sandisk 32g ultra gave me nothing but trouble and then it died. It is going back to Amazon. I suspect a bad batch of cards.

I got mine from Low Lat Plaza in Kuala Lumpur in September. It could be a bad batch. It is strange that it is only the 32gb ultra that is affected.
Looks like it is time to get a 64gb class 10. I was trying to wait till my next trip to Asia in June but now might have to bite the bullet sooner.

What kernels are you guys running? I had this problem last night after flashing a new kernel, I couldn't get my card(Sandisk 64gb class 10) to mount at all. As soon as I flashed back to Perseus it mounted just fine. Random thoughts, just something to check.

I'm having the same issue (SD card removed every couple hours, but not every time it goes to sleep) with a PNY 32gb card, FYI

Galaxy S3 and SD Cards

Hello Guys.
I've seen this problem on a few forums but no one really has the solution that might work for my phone. Whenever I add videos or movies to my external SD card, in a few hours or days my SD card starts acting weird. Some of the pictures get deleted or destroyed and sometimes I cant access my SD card with CWM. When I play the videos I can't fast forward (doesn't let me) and sometimes the movie plays for 2 minutes and then just starts from the beginning again. I tried formatting it several times in fat 32 and exfat and it gives the same problem. I tried using different SD cards from sandisk and still causes problems. I am currently using the 64gb san disk SD card. My phone is SGH-T999. Also, for those who are wondering, I did try different roms.
Any solutions?

Have you tried using 32gb card or less?
The 64gb cards shouldn't be full compatible

64gb cards are fully compatible. If not, they wouldn't work. To the op. Contact SanDisk. I had a couple of 32gbp SanDisk cards do this to me. They sent me new ones for free even though they were 1 and a half years old. Now it works fine. I am using a 64gbp card now with no issues.

Yeah, I think the best solution at this point will be contacting them and asking them for a new one. But to be completely honest, I used a generic one and it gave me the same problems. Then, I thought I should stop using cheap crap and bought a SanDisk and still same problems. I guess the problem is in the device?
