I purchased a 64GB Transcend SD card on Amazon. I'm replacing my 32GB SanDisk. I initially put the card in after transferring all my files and formatting the card using exFat. I then noticed my phone was heating up. I formatted the 64GB SD card using my Note 3 and it formats FAT32... but when I connect it to my Mac after format, it gives me an error [not readable].
I'm currently formatting it on my Mac FAT32.
Anyone else had an issue like this before?

Greetz people!
My problem is that my Herm200 wont regonize 2gb micro sd cards. Ive tried with SanDisk 2gb (not ultraII) and Kingston 2gb card. I use my Kingston 1gb card with no problems and have tried Kingston 512mb card also with no problems.
Ive tried formatting with fat and fat32.
Any ideas?
And im running Schap's 3.57a rom, wich is a great rom by the way. I tried the SanDisk card with other roms too, so i dont think the problem is related to the rom.
Dumb questions first - can a PC card reader access the card? If so, what filesystem is the card formatted in? Can't remember what it needs to be (FAT or FAT32) but if the PC can read it, format it to each until the phone can read it.
Yes card reader can read both of the 2gb card's (i have them both here) and i have tried fat and fat32 systems.
Strange since the Newer ROMs support 4GB cards the only thing I can think of is try playing with the card while its in pushing it agenst the contacts or pop the battery out and push the contacts down a little so it makes the card fit snug. I have no problems and never had with my 2GB scandisk SD card. also search the threads there was lots of reported problems before with SD cards but most of that was fixed with the new ROMs
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:

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.
Something I've been meaning to ask, simply because it's a wierd occurrence. A few days ago, I got a new 64gb Samsung micro SD card. Naturally, I had to format it into FAT32. I went to format the card using my S III (because it has helped put both my 32gb cards into FAT32). Format successful, and I moved a bunch of backup files from my other card onto it, and hooked it up to my Galaxy Nexus using my Meenova reader. The storage mounted, but it couldn't be accessed. The format of the SD card, I found out, was exFAT, not FAT32. My question is this: why when you use the device to format it does the 64gb card get put to exFAT instead of FAT32? I had to use my laptop to format it I to FAT32, just like the last time I got a 64gb card.

I've always had to use my pc, I think the phone is only set up to format it in exfat because you can transfer larger files than fat32. I may be wrong though.
G3 rooted on VS98510B
128gb Lexar UHS-1 microsd 633x,,, the blue and black card.
Phone refuses to recognize card is inserted. I have searched other similar issues and tried solutions,,,,nothing helped.
Tried card formatted from factory Xfat, formatted to NTFS, formatted to Fat32, used SDFormatter back to Xfat..... card was checked for fake capacity using H2TestW.
Card works perfectly in PCs and camera.
Same card in 64gb version recognized immediately,,, just like my other cards.
Card is not seen when attaching phone to PC either.
Phone refuses to even see the card. (so mount option is not available)
Battery pull and restart = nothing
Do not have someone elses phone to try it in.
This is the only 128gb card I have tried,, don't have another one.
