If you have a pc or laptop try to format in fat 32 has work for me
that 64 GB can be formatted only NTFS or exFAT, today I'm going to buy SanDisk 16 GB class 10 and test it
I purchased 16 GB Sandisk Ultra class 10 and after factory reset card is finally recognized, problem solved

I have a Sandisk Ultra SDXC 64GB Class 10 UHS-1 Micro SD card in my T999 T-Mobile Galaxy S III phone.
The card has become "damaged" (Samsung's term). 4 times now. Please note that the card works fine on my Window 7 PC. This last time I formatted the card in the phone, put the card in the PC, copied a bunch of files to it (about 3GB) and then put the card back into the phone. And the phone said that the card might be damaged. I was sure to unmount the card before removing it.
I called T-Mobile tech support and they know nothing about it.
I called Sandisk and they said "There are known problems with Samsung Phones and Tablets and Sandisk Class 10 cards. Samsung is aware of this and working on it. Would you like us to replace your Class 10 UHS-1 card with a Class 6 card?"
I called Samsung tech support and they know nothing about it and are not setup to tell their engineers about issues. The only way to report an issue to engineering is via email.
Let's make a loud stink about this so Samsung/T-Mobile will fix it.
Follow up on original post:
I went out and purchased the recommended Sandisk 64 GB SDXC Class 6 memory card and the problems are exactly the same as with the Class 10 card.
The problem seems to appear when there is more that 4GB (I'm not sure if it is exactly the 4GB barrier or not) on the card the Galaxy S III has a problem mounting the card. Note that once the card has gone greater than 4 GB even deleting files to reduce it below 4 GB does not allow the card to be mounted.
On the class ten card I was able to successfully run the fsck -t exfat command on the card that Android would not mount. fsck returned no errors or problems found.
My testing is rather limited but I can say: The T-Mobile Galaxy S III (T999) does not work correctly with SanDisk Ultra 64 GB SDXC memory cards (class 6 or Class 10)
Please, let's spread this around so that maybe Samsung, T-Mobile and SanDisk will learn how to work together and solve the problem for the sake of their customers.
I put the new card in the phone and formatted it in the phone.
I don't quite understand how you got 2 crap microsd card, I'm using a Samsung ultra 32gb class 10 just fine, never had one problem mounting it never seen one error message. Sorry

I think it is a software problem with the 64 GB Micro SDXC Card.
I have a Sandisk Ultra SDXC 64GB Class 10 UHS-1 in my Galaxy SIII and have never had an issue. I had problems formatting the card in my PC, So i just threw it in the phone and formatted it there. It was formatted and I have loaded about 25gb of music, 5gb of pictures through Cheetah Sync without issue.

Have you rebooted your phone or unmounted and remounted the card? That is when the problems occur.
I believe that there is a bug in the code the Samsung uses to check the card prior to mounting. They are doing more than just a simple
fsck -t exfat.
I tried a 32 GB SDHC Samsung Class 10 card with the exact same data that was on the 64GB SDXC card without any problems. It is my belief that there is a bug in exFAT code in the Galaxy S III.
Thanks for your comments.
I have only unmounted the card twice to kickstart the media scan after loading some music and I reboot my phone every 2 days or so.

I've reboot my phone all the time—I don't have any problems. I don't mount/unmount very often, but just tried it now and everything appears to be fine.
My card is a 64 GB class 5 SanDisk, formatted FAT32 (done on a Linux machine).

I believe the bug is in the exFAT drivers in the S III.
I formatted the card in the S III under the mistaken assumption that the phone would know best.
The theoretical maximum size of FAT32 is 2TB. However, since Microsoft in their infinite wisdom decided only to support FAT32 up to 32GB (most likely to force people to use NTFS) support for FAT32 above 32GB is spotty and unreliable.
This being said if you format a 32GB card or smaller in the Galaxy S III, it will be formatted FAT32. If you format a 64GB (or greater I presume) in the Galaxy S III, it will be formatted exFAT.
I will try formatting the card as a 64GB FAT32 partition. However, this will mess up my using a USB 3.0 card reader (at 5Gb/S transfer rate) to write to the card. Writing to the card via WiFi is interminably slow by comparison.
Sounds like windows is damaging the exFAT partition when you plug it in to your computer to transfer stuff. I've never done that because I just use Cheetah Sync to sync my iTunes(25gb) folder to my sdxc card and to sync my pictures/videos from the sdxc to my pc.

Seems that way to me too. exFAT is not in Linux upstream, so I imagine Samsung just bought a binary driver from someone. Who knows the quality.

What does the card reader have to do with it? I've a USB 3.0 card reader, and my 64 GB FAT32-formatted fine.
As I recommended in the other thread, use a Linux Live CD to format your SD card.

or use Partition Wizard Home Edition (free)(windows) for large fat32 format jobs works perfectly and the price is right http://www.partitionwizard.com/free-partition-manager.html

Because I thought the same thing one of the tests that I performed was to never remove the card from the phone. I did all of my copying to and from the card via File Expert Web Sharing. One day I ran the phone battery down and the phone rebooted. When it came back up it was unable to verify the card. However, fsck -t exfat found no problems with the card.
One interesting point, I was using Cheetah Sync (a great program) last night to copy a TitaniumBackup directory to the phone and it failed. Here is a copy of the email I sent to the developer:
The destination directory contains 11,841 files totaling 2.93GB and Cheetah needs to download 1917 files and is failing on the 1st file with the error "Sync Error - I/O error downloading files.".
Note: Cheetah Sync had already copied almost 7,000 files. It originally failed during a copy of almost 9,000 files. I restarted
the sync and that is why it failed on 1 of 1,917 files.
I am using a T-Mobile Galaxy S III (Model SGH-T999) with 32 GB internal memory and a 32 GB external SD Card (Samsung Class 10).
The source directory is c:\phone\card_backup\TitaniumBackup and the destination directory is /mnt/extSdCard/TitaniumBackup.
I am able to manually create a file in that directory using a file explorer.

The card reader is not the issue just the mechanism to allow me to copy files quickly from/to the card.
How Windows will handle a FAT32 partition greater than 32GB is my concern. In the past I have always used NTFS for drives/cards greater than 32GB because FAT32 has a 4GB - 1 file size limit and I have many video files that are larger then that.
MiniTool Partition Wizard and Easeus Partition Master can both also make a 64GB FAT32 partition.
Thanks...
Update
There is an update to this thread here:
http://forum.xda-developers.com/showpost.php?p=29904990&postcount=10
I have been having problems switching from a 4gb sd card to a 32gb sd card in my htc one v. The 4 gig runs perfectly fine in my phone but I need more space so I switched to the 32gb card.
The problem I am having is almost instantly after putting in the 32gb card my phone starts lagging on just about everything. Load times take longer, the phone has more graphical glitches etc. I tried formatting the card to nfts and running paragon software to use that file type. Still no hope. I also partitioned the card to 16gb and free space for the other half and still no luck really. Though I did see some improvement.
Is it just that I got a bad sd card? Note that it works with my laptop and also in my pc perfectly fine, the phone just seems to not like the card or larger file size. Has anyone else gotten a 32gb sd card to work in their htc one v?
Thanks
Derek
Yes my 32 gb transcend class 4 works perfectly,no lags,try formatting it with fat32 with the help of your pc like I told you once before.

I have an ADATA 32gb class 10 card. I will try that
Edit: Ever since I tried partitioning the sd card with MiniTool Partition Wizard the card won't show up on my pc. The software says that it is a (Bad Disk). Note that I can use the card perfectly fine on my macbook pro and the phone also recognizes the card. If I put the card into my phone and connect with USB it works fine.
Hi folks,
I recently got a 64 GB microsd card ( class 4) for my galaxy note 10.1 SM-P601 ( build:JSS15J.P601XXUBMJ9,Baseband601DDUBMJ1).
This card works fine when I use it on my laptop but I am unable to write it on the tablet.I am able to read the data though.
Below is the list of what I have already tried and failed.
1)I have tried rebooting,remounting reinserting
2) As the default format was exFAT I reformatted it into fat32 using fat32 formatter.
3) I tried partitioning the card on laptop into 2 32gb partitions and then using it on the tablet.
4) I have tried SD card accelerators from Play store.
Once I mount the sdcard it shows TOTAL SPACE: 62.5 GB in Settings->General->Storage.When ever I try to write the card it somewhat gets unmounted and shows TOTAL SPACE :0.0 bytes.
Please suggest a solution to make it work

Have you formated it in the GN 2014?
Also, I wouldn't use a Class 4.. Just my opinion.
Also, they have some bad 64gb cards out there.. I would get a name brand 64gb class 10 from BestBuy, Staples, etc.. Format it GN 2014. If everything works, then the problem was the sd card.
I have a Sandisk Ultra 64gb Class 10 in my GN 2014 and my Note 3.. both work perfectly.
Hi gurus,
The Idea is to make the the 64 gb card (that working fine on my laptop) work on my note 10.1.
Please help .
What could be the possible reason.

As you have tried several things, can you please tell us exactly what your situation is now so we can help you.
If the card is a used one, it may have been formatted as FAT32, to work in a non-Sdxc compatible device. The Sdxc capable note may boycott the card because of violation of the specs, so reformat it to exFat.
It was similar with 4GB SD cards, which shall not exist by spec, but worked fine in Sd devices, not in Sdhc ones.
Experiencing the same

Hi maainux, I'm experiencing the same problem here, have you found any solution?
Mine is a SM-P601 / Android 4.3 / Build: JSS15J.P601UBUBMJ4 / Baseband: P601UBUBMJ1 (Fully Stock)
I tried 3 64gb micro sd card: SanDisk Ultra, Samsung, and a generic one. For both 3 the same results, as following:
1 - If I let the tablet format the card (exFAT), it can be mounted but gets suddenly unmounted when I try to write on it and shows TOTAL SPACE :0.0 bytes just like yours. I installed BTSync, when I tried to configure the sync on the tabled by selecting the sd card as the destination folder for the files, the app give a message saying it don't have permission to access that folder and gets unmounted. Tried rebooting, remounting, reinserting, and nothing change.
2 - If I format to fat32 as a logical partition using Minitool Partition Wizard, I get the same behavior as above description.
3 - If I format to fat32 as a primary partition using Minitool Partition Wizard, I can create folders but can't delete them, when I try to delete via "My Files" it says "deletion failed". I tried ES File Explorer, get the same. I was able to configure BTSync, it can copy the files from my PC folder, but when I delete some file in the PC it can't be deleted on the tablet and the BTSync app shows a message stating it can't identify the destination folder on the tablet.
I have some micro sd cards laying around, tried SanDisk 32gb, 16gb and 8gb, both 3 worked flawlessly on the tablet. I noticed the tablet format any <32gb card as fat32, and the 64gb as exFat, this make me think that was related to file system format, but it's not. Seems something related to permissions, like the KitKat 4.4 guys are experiencing. The point is I'm completely newbie on Android and have ZERO knowledge on Linux/Unix, so I have no Idea on how to solve this.
Can you guys help me?
Thanks in advance.
Hi guys
have you found any solution?
Thanks
So I've spent hours trying to get my Patriot LX 64 GB Class 10 UHS-1 microSD card working and I'm not having any luck at all. I format it with exFAT on Windows and it works great. I install it into my ASUS T700 Android tablet and it works great. Plug it into the Samsung, and it starts locking up and freezing - usually until I take the card out. I tried live chat and they kept telling me I had to format it to FAT 32 in Windows...and I spent an hour telling them you CAN'T format a > 32 GB card with a FAT32 partition in Windows! They just quit talking to me and told me to call Patriot.
I see on their own support page, they tell you to format larger than 32 GB cards with ExFAT so that's what I've been doing - even tried NTFS but that won't even see the card.
Has anyone else tried a Patriot 64 GB microSD card that works?
I also tried a 16 GB FAT 32 card in it - and it works with no problem at all!
So....if it's not the card and it's not the tablet, is it a combination of these two particular brands?
hi all,
i have 32 gb sandisk microsd card class 10. when i write data on card, after about 20-25gb later something happens and card creates uuuuuu.uuuuuu files in uuuuu.uuuuuu files. it goes infinite. anyone know about this issue and how to fix it?
