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.

Yes. Put in the 64GB SD card, go to settings (storage), unmount, format SD. Your microSD should now be partitioned the right way to use it.

I tried it but it won't read as it is a 64 GB card for some reason or its not reading it at all , I don't know if I had to go back to ICS ROMs or what
Sent from my SGH-T989 using xda premium

You have to format it in FAT32 with your PC.
If you Google it, you will find a little program that will do that.
I know there is a thread on XDA about this, but I'm at work and don't
have time to search for it.

Do you have a Blackberry around? That happened to my microSD when NOTHING at all would read it. I just stuck the card into a Blackberry to see if the card was broken. On the screen, there was a pop-up that said that I had a new memory card inserted and it asked if I wanted to format it. I hit yes, and all of a sudden, my microSD card started working again.

Can I ask where you got your 64gig card from and how much it cost? I would really like to get one. Thanks

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.

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.

External SD card problems

So today i noticed that my SD card was getting really hot and i ended up getting a sd card blank or not formatted message. I installed another card and it works fine. I put the oringinal card in my computer with a card reader and wont even register. Is my SD card fried? Im on FH13 with exynos abuse root. Any help would be appreciated.

Sounds like a dead card. If it is SanDisk, they have a lifetime warranty.

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?
