Did you try formatting it from the phone?
Also, is it definitely genuine?
Format from the phone storage menu usually sorts it out.

Does the S III supporte SDXC (exFat) file system?
Try formating it to Fat32 or NTFS, should do the trick...

SANDISK 64gb micro SDXC are preformated in: ExFAT.
So I managed to REFORMAT in : FAT32 Only
And now it is working.
But....
I have previously mounted the 64gb Micro SDXC in my STOCK and UNROOTED ROM right after the unboxing, and it worked fine.
So the problem must be the ROOTED roms.

Yes it is GENUINE,
and
NO It DOESN´T revolve the problem formatting from the phone...
I had to reformat from PC in FAT32, phone formatting does it in ExFAT....
The problem must be from ROOTED roms, they DONT support ExFAT

If you were on a custom ROM, that was more than likely your problem. There are no issues with SanDisk 64 GB MicroSDs formatted in either ExFAT or FAT32, when used in a SGS III with a stock ROM.

Root does not affect exfat hiwever not every kernel has the exfat module included so if you installed for example cm9 your exfat partition would no longer work because cm9 doesnt support exfat. Further more the install process also breaks the formatting of the card so it will then no longer work in anything at all and you have to bang it into a computer and run chkdsk /f on it to sort it.

Not able to mount an 64gb microsdxc on S3
I have tried to mount the micro sdxc as I took it out from the box and the phone does not recognize it. I tried to format it again on computer as exFat but still no result . I tried to format it on computer as NTFS still no result. when inserted in phone i tried to mount it and nothing happens . Any idea how to make it work ? Previous I had an 16 gb micro sdhc which worked perfect . Thx.

Finnaly I solve the problem . I put the microsd in an galaxy S1 and I was able to formate it there. It showed immediately 59.4 gb. When i put it back in S3 it showed the same . Good luck if you encounter the same problem.

[Q] Will the SIII support 64GB MicroSDXC exFAT or not?

During the launch presentation it was mentioned that the Galaxy S3 will support MicroSDXC cards with capacity up to 64GB and an exFAT file structure.
However, the manual released on Samsung's UK website states otherwise...
http://www.samsung.com/uk/support/model/GT-I9300ZKABTU-downloads?isManualDownload=true#
Code:
Your device accepts microSD™ or microSDHC™ memory
cards with maximum capacities of 32 GB (depending on the
memory card manufacturer and type).
Code:
Your device supports only the FAT file structure for
memory cards. If you insert a memory card formatted
with a different file structure, your device will ask you
to reformat the memory card.
The manual is from this month (05/2012), Rev. 01
I asked Samsung, but they weren't able to give me an answer.
So, what's the deal?
Nothing is the deal, MicroSDHC and MicroSD"XC" are compatible using the same controller, the only reason why it wouldn't work is if someone went "If >32GB return IMPOSSIBRU;"
We know the s2 deffo doesn't support 64gb but this guy tested it out and it worked..
http://www.youtube.com/watch?v=yYUg14u_co8
http://www.youtube.com/watch?v=Fv_56mwG0w4
These are two videos that show that it works..
Yes, yes it will on both counts.

Got confirmation from Samsung Mobile UK:
The device will support 64GB micro SD. Sorry for any confusion.

If you format the card in the phone, what format will it use? Presumably FAT32. If so, will it be better to format in your computer?
The 64GB cards come formatted exFAT, so no need to format a new card at all (otherwise in computer if the card is already used). Just confirmed I will be getting hands-on an S3 today, will by trying out my exFAT formatted 64GB card in it

Obviously I will!
Hopefully the guy is OK with me taking video and isn't under some oppressive NDA, if so will shoot a bunch of stuff including the card.
Hi everyone!
So, I did indeed have a couple of hours hands-on time with the S3 today, wanted to let everyone know that exFAT support is present and working, and 64GB cards work fine (if anyone still doubts that they work on all Androids with card slots).
Will have some more info up soon too
Hey guys,
I just got a Sandisk 64GB SDXC card. I popped it in my SGS3 but it tells me that the file system is not recognized.
Any ideas?
Thx
reformat the card in the phone the 64 gig works fine even on my old sgs but you have to reformat it on the phone

Thanks for the reply. I'm starting to think there is something wrong with my card. My SGS3 cannot mount it, then it asks to format it but that gives errors and ends up saying I can now safely remove it.
I have tried to format it on Windows 7, I can select exFat as the file system but it tells me the capacity is only 30.6 MB. Weird.
You might want to check you got what you thought you were buying, google for H2testw. Plenty of no-what-they-seem-to-be cards about.

Got one in my S3.
Works great .
You definitely need to format the card from the device (S3) before using it. Otherwise you won't see it at all or only half of it.

Question?
Hi guys, i have the 64gb SanDisk sd card... I had formatted it EXFAT using Windows 7. My phone (galaxy s4 gt-i9300) recognizes it, but i dont know what is wrong, cause I cant download files bigger than 4GB... And also my recovery recognizes it. I rooted my phone, but if I check the properties of the sd card on Windows it shows that it is on EXFAT? Should I use a different method to format it?
Thanks in advance
Sgs4 its not gt 9300.

(HELP) Anyone having issues mounting 64gb sandisk sd card on S III

Hi there guys
I have been having a problem with 3 sandisk 64gb micro sd cards. I always got them replaced but it is getting frustrating now. Obviously they are formatted in exfat format.
The problem starts when I copy data of over 30 gb. Once i copy the data n the sd is remounted or the phone is restarted i always get the message "damaged sd card" but when i read the card on pc through an adapter it shows the contents ok. So i want to know if anyone can help me so that I may not need to return the card this time around...

Try to format it first in the phone, then start loading data on it.

I also tried it buddy but none of the methods seem to work .. i also tried formatting it then copying data through sd card reader as well as the phone itself... does it have to do anything with some file system issue or kernel related issue... im on stock kernel rooted...

also had the same problem. i formatted the card to fat32 with 32xxx sectors with "GUIFORMAT" app for windows, the it works ok.
then after fat conversion, you can try to format the card to exfat using any app (not the windows one) search google, then it might work, didnt try myself as fat32 works great, and i can use it with the script that makes the card the phone memory, so now i got 64gb instead of 11.6gb of phone storage

I have the class 10 64Gb Sandisk sd card too with no problems.
Card has about 55Gb info on it and I didn't format the card. Just put it into the phone. Recognised instantly and haven't looked back.
I have a 2nd SGSIII too with a 64gb class 6 sandisk sd card. Same applies but with a little less data on it.

SIII Liquid Smooth RC5 cant use ext. sd card.

Hello,
I'm having problems with sd cards and liquid smooth. Sd card works in recovery mode without any problems, but in the actual OS it doesnt. It says it's damaged and says its needs to be formatted. However it gets stuck at unmounting the sdcard. I've formatted in the recovery mode, but it didn't help. I've been searching the internet for a while and haven't found anything helpful or anyone with the same problem. SD card is Sandisc microSDXC 64gb class 10.
List of software whats loaded into the SIII at the moment.
ClockWorkMod Recovery 5.5.0.4 - "v1.5"
Liquid Smooth RC5
superSU v0.89
With best regards: Amatheas
Format via Windows as FAT32 .

Well. I did get it to work, but at half capacity. Apparently my laptops sd card reader cant read more than 29.8gb of the sd card. Is there a way to format it using android itself or is there a trick to do it on my laptop?
EDIT: Got it to work. ZTE blade had the ability to format it to 64gb version. Thanks everyone for help. This thread is now solved.

[Q] MicroSD Card File System

I've just bought myself an SGS3, and a 64GB MicroSD. My MicroSD card has arrived before my phone, and I'm wondering what file system I need to re-format it as, if any? It's currently formatted as exFAT. Thanks in advance.

For compatibility, its best formatted as Fat32.
If you're using a samsung rom then exFAT is fine.
If you go aosp roms like cyanogen, you'll need fat 32

what kind of card is it?
are other cards affected as well?
if not then put your card into a pc and try to format it to fat32 and try again on your phone. if pc does not recognize it either then the card is probably broken..
Is a dam disk ultra 32gb card. It's already in fat 32 file format. Still, formatting it using a pc worked for me.

then i do not really know.
maybe only for testing try to format it on pc to exfat. i know in fact fat32 should always work, but it could be worth a try.
i also have often read that s3 has some problems with certain sd card brands, and mine also already killed my last sd card. since i bought a samsung sd card there were no more problems for me..
Bro my problem is resolved after I formatted my card in a pc. It's still in fat 32. Thanks for your help.
