Card problem

Hello, I'm new to the forums.
Today I bought a 32 GB MicroSDHC memory card for my at&t s3.
Behaviours:
1) I inserted it into my phone and then I tried taking some photos. I set the output path to the card and I took a picture. The picture was successfully saved to the sd card, but when I tried taking a second picture, I received an error: "Cannot write file in SD card. Default storage set to Phone". If I try again to set the memory card as default storage I can again take another photo, but the next one will fail as described again.
2) With SD card mounted to the S3, I plug in the USB to connect it to my computer. I can then see the card and view the files on it. However, I'm unable to write anything on it. (Copying something to the card will freeze my windows explorer)
3) If I insert the card into my computer via adapter, then all works fine. I can write to it fine.
It seems that the problem only occurs when the sd card is used by the S3.
Note: I have checked the card for read-only notches and it has no such thing.
Note2: I have a rooted phone running JB 4.1.1 stock.
Any help will be appreciated. Thank you.

Maybe you can try reformatting it.

reformat it in what way? I've already tried exFat, Fat32 and NTFS. NTFS and exFat give a "blank card" error, while Fat32 won't let me write stuff like I described. And I've reformat the card a couple of times already.
Edit: well, I did so using windows format app.
Do you know of other better apps?
Also I forgot to mention that I can't format the card via samsung s3 built-in app because it always returns "blank error" in that case.

I also had a problem with a new card and I took mine out and put it back in the phone and it finally worked. I just made sure it was pushed in all the way and seated properly.

I have just tried to use the card on a Galaxy S Plus. It worked flawlessly. I format it from that phone and then I inserted it into the Galaxy S3. It still won't work on the S3.
Why is this? I'm becoming desperate. This issue is bugging me a lot. Please any help will be appreciated.
Update: Even tried a galaxy S2. It works fine. Same problem on S3 though.

I have a similar situation. 64Gb Sandisk Ultra card unmounts while formatting. Cannot write files to the card. Reading is perfectly working. Tried formatting in pc. Not getting formatted. Tried several methods, like through dos etc. Still no change.

I'm using aLenovo A7000 running on ressurection remix V5.5.9 in which i don't have the option to unmount my sd card.Please suggest me a way to do it and also while transferring files from my pc on my phone...i switched my phone from a mass storage device to the'charging only'option and after that my phone doesn't get recognised at all by my pc as a usb mass storage device.... And i can't even find those options anywhere in the settings and usb debugging also isn't working.Pls help me ASAP!

My 16gb SD card also does this. Before it started though, all of my music files on it became damaged, but would still play partially, then end prematurely. I think this may just be cheap ass SD manufacturing. I say just boycott SD and get the Samsung card.

Solution / Fix:
Install Wake Lock PowerManager on google play. Enable Partial_Wake_Lock then viola! No more unmounted / eject problems. The problem is everytime your mobile is in sleep mode, the unmounting error occurs.
Also install SD Card Monitor to check the counter of mounted/unmounted/ejected sdcard.
Hope this helps.

Stupidest post 2016

[Q] Fail to download and or write to SD.

I have scandisk class 10 SD card 64 GB.
its formatted using the note 8 device (exFAT).
Whenever I try to download a file or copy a file in note 8 to the SD. It fails and reboots my device. knowing that reading from the SD is perfect. I can play music and movies from SD with no issues.
the only way I can transfer files to the SD if I connect the SD to the PC directly.
I am not sure if this is an issue with Note 8 or SD. please help!

Mine does the same thing. Ive tried formatting in exfat and fat32, didnt help. It writes fine to an old 16gb class 4 card ive got but not the 64gb. Sucks but at least it reads fine

I have SanDisk 64GB (xd1 afair) exfat formatted in N5100, and it works ok with stock ROMs MD1'S and MF2.

I am not using any custom Roms. And i formatted my sandisk ultra 64gb more than three times but the same issue keeps happening. I also tried to find other apps to transfer movies and music files from Iinternal memory to sd but that didn't help. I can't even download directly to my sd. It reboots my note 8 if I try to download or transfer files to my sd.
Any suggestions?

I'm afraid nothing beyond painfully obvious ones - trying with another similar card, trying the card on any other device supporting exfat (if ok, this would provide definitive proof that card is ok), trying on freshly installed latest ROM, trying with the same card formatted in fat32.

device does not need to be hardware, it could be on the soft side as well, in such case reflashing/changing ROM could help

It seems like this is the last resort. I will reformat my note 8 and try again. I also forgot to mention, that few weeks ago I was able to transfer one 800 mb file but this stopped happening. So it seems like there is not enough memory to transfer although I tried clearing the memory.
I will let you know if this reformatting the note 8 will fix the problem.

Reformatting the device didnt fix my issue. I am not sure now if it is the device or the SD. I need to test my sd in other devices and check if it will allow transferring of files

I am having the same issue as well. I try to move files from my internal too my external card and device reboots. I have the SanDisk 64GB card as well, it works fine in my S4. Could it be a software issue on the Samsung side?

Do you have a V500 or V510? I have a Sandisk SDHC Class 10 32gb card on my V500 and it works fine...

I would try to format it to fat32. Also, what are you using it for? If you want to move apk's, you will have to use something like link2sd. If it is just for media, no worries.

Thanks for reply?

This isn't normal. I would first try a different player. If it's not the player, then I would suspect a corrupted SD card. Have you used the sdcard on another device? I mean, a current device. Doubtful it is the tablet, but you never know.

[Q] MicroSD Question/issue

I have the Tab pro 12.2 KK4.4.2 and purchased a patriot Micro SDXC 64 GB. My question is similar to other posts and I will try the posted solutions when someone can confirm the validity of the SDcard. Samsung specs for the Tab(SM-T900) state support for micro SDHC up to 64 GB. All of the reading I have done shows that the largest SDHC cards is 32GB and anything larger is a SDXC. So is my64GB SDXC card actually supported in my device? I have not been able to write MP3 files from my PC to the card or any other files with any success. Put I am able to do it fine on a smaller 16GB SDHC card. Can this version SM-T900ZKAXAC be rooted?
Thanks

I contacted Samsung and they are going to escalate the issue up the chain. It seems as though the tablet only supports Fat32 file system, while SDXC cards are only can only be formatted using exFat or NTFS. That being said I tried formatting my card with NTFS in hopes it might allow Fat32 after but it wouldn't format using NTFS.
Is no one else having this issue, as I have not seen 1 other post regarding this particular problem?

Mossey, do you happen to have a Windows computer?
plug the sd into a different phone if you can and connect as external. Click Start->My computer->right click and format to Fat32. I do this all the time

I thought for second you had the solution. I have another tablet and tried reformatting using it. I had the stick showing fat32 file system but it was 32gb vs 64gb. But the tablet recognized it initially, so l reformatted using the tab, but now the tablet looses the sd after it writes a few files to sd. Then if I try to view files on the tab, I get a message that the ext sd card may not be readable.

Hm interesting, it seems like it might be a permissions issue.
Can you try doing this on a device that runs something before 4.4.2? Kitkat is known to cause lots of problems with SDcards
hope you find the solution.

Again- Thanks. I thought it odd as well and it didn't add up. Although the SD card was working OK in my new Sony camera I decided to return it to C.C. for an exchange, voila problem solved. This still tells me that Samsung Technical support is useless. Everyone spent a lot of time trying to solve this issue. I still am finding odd things happening with Kies but I have found some work a rounds.
