32GB SanDisk SD card is read only - Galaxy S III Q&A, Help & Troubleshooting

It started about two days ago when I tried to do a nandroid backup and it failed..
Anyhow.. It simply won't let me delete old files or right new ones and when I checked it said the card is read only..
What can i do to fix it??
My phone is I9300XXUFME7 on Nightmare Rom with the SanDisk SD card of 32GB in class 10 format.. I was sure I bought the best one for my phone :-\
Thanks in advance

Are you saying that your SD card is write-protected ?

[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=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

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.

Hi Friends,
I am using Karbonn A9 (Without Rooted) & micro SD Card - 4GB class 4. I can transfer the files fine b/w PC & Card using USB cable. But, now-a-days, the files copied to sd card doesn't appear after usb unplugged from PC.
Also, the files deleted from PC, appears on SD Card, when removed. Please help me.
Have you tried to format your sd card?
I have have never had problems with class 4 sd cards until recently. I have had to buy all class 10 sd card for all of my devices that I have upgraded to ICS/JB. I don't know why, but I started getting all sort of problems flashing, saving, FC's. It was really weird. I didn't realize that it was the sd card until I switched the sd card in my tablet (with was already a class 10) to my phone. With worked fine in my phone, then my tablet started acting crazy.
this happen because u already click fix permission.. don't ever choose fix permission in cwm.. u might getting fc..

Sorry for late reply. Surprisingly, i didn't got email notifications for your posts, so I am unaware of it.
I had done formatting several time in XP, but still the problem persists. Also, Sometimes it works fine, sometimes it doesn't work...

64gb SD card ... getting "damaged card" error.

Just bought a new sandisk 64gb card. When I try to mount the SD card I get "damaged card" notification in my status bar. I selected it and it gave the option to format. I did but to no avail. Will this ROM support that size?

I ran into the same problem before. Sadly, the Note does not support 64gb sd cards. The max that you can get is 32gb, unless someone out there can prove me wrong.
Been running a 64GB samsung card in my I717R since release date without issue. I did originally format the card in another phone.
If you need help please use the correct forum. Moved
Is the card formatted to NTFS ?....or FAT32?
also ....is the card an SDXC card ?
Been reading for a bit to attempt helping, and the card should function fine if first formatted to FAT32, but as stated by agoattamer ..cannot be done by the usage device.
Perhaps via card reader and PC ?
Hope it helps a bit ..g

I am using a Rogers branded Note with stock ICS. I purhcased a 64GB Sandisk MicroSD a while back. Out of the box, it would not work, as the card was formatted in exfat. I had to format it to FAT32 first.
Unfortunately windows 7 did not allow this.. I think the card was too big. So I had to google how to, and used a free utility to do it (sorry, I do not recall the name of the app).
Works great now
I did find a fat32 software that works. I only got 59.45gb out of it. I used 32768 for the allocation size.
Would a larger allocation size get me the full 64gb available?

You won't ever get the full 64GB. It is just how it is. Check your hard drives on your computer and you will find the same result.

I had to format my Samsung 32GB class 10 card on my Z2 before it recognized it, some phones do the format differently, just use a PC with a card reader to copy your stuff off it then fire it into the Z2 & format it in the storage section of settings.
I will try but it was fine it just suddenly happened! My sd card was working!
who told you samsung sd card is the best?? it is the worst. buy sandisk,lexar or sony sd card next time
Just format it to exfat, it is supporting 64g and above, and it is meant for sdcard/ssd storage
My Samsung pro reads and writes at 90/80mbps. I'd say it's about the best.

If the card isn't unmounted before taking it out it will ask for it to be formatted as it won't recognise it. It's a pain with this phone because to put the card all the way in you need to push it in with something like the end of a pen because the slot is deep inside the edge of the phone so that a waterproof flap can go over it. As a consequence it's easy to not quite push it in fully, but far enough for it to get a false read, which will cause it not to be recognised when inserted properly and require formatting.

Also, beware when you're formatting a 64gb SDXC card using a USB reader. The reader itself has to support SDXC otherwise the card will be FUBARed. I accidentally killed my first 64gb card twice that way - thank goodness the shop didn't ask what happened when I requested an exchange.
