Formatting exfat to fat32 - Galaxy S III Q&A, Help & Troubleshooting

If you have been having issue with exfat card even after formatting it to fat32 this is probably the solution for you
The 64gb exfat card i have never worked on custom roms no matter what software i used to format it to fat32.
But finally it worked with this one software, Just make sure you follow the instruction correctly.
http://software-files-a.cnet.com/s/...&pid=12572695&psid=10863346&&fileName=epm.exe
First use easeus to delete the partion in 64 gb card.
then Click Start menu, select Run and enter diskmgmt.msc
You need to find the disk with unallocated space. Right click on it and select "New Partition" and follow these steps, clicking "Next"
Enter the maximum size for the Partition Size
Choose assign a drive letter. I used F:
Select "Do not Format this partition"
Click Finish
Now you have a drive letter, this is what we will pass to the formatter
http://www.ridgecrop.demon.co.uk/download/fat32format.zip
Now download a copy of fat32format. Extract the EXE file to C:\
Click Start->Run and enter cmd (as admin)
type this - C:\fat32format f:
enter y to continue
Now the sd card should work on phone.

An easier alternative which doesn't require CMD or the use of multiple tools is HP Usb Format Utility:

If it works then sure. i already used 3 recommended softwares all failed so i dont know if this will work.

Thanks for this guide

I always format and re-partition in Linux ...
I always format and re-partition in Linux ... and currently all my large microSD cards have been re-partitioned with the following layout:
- free space (4 MB on 32GB, 16 MB on 64GB - since that's how those came from factory )
- main partition (primary partition 1 - I format that as Fat32 in Linux but then I go to Win7 and re-format to exFat; exFat works perfectly in Android 4.x from Samsung (and good mods) and the CWM recovery from CrisKelo ROM can work just perfectly with exFat when doing backup/restore; other (even newer) CWM versions/alternatives might NOT be OK with exFAT or stuff over 32GB!
- 512 MB Linux swap (primary partition 2) - this gets mounted by special mods that give the kernel virtual memory
- free space at the end (at least 4 MB on 32GB, at least 16 MB on 64GB)!
The only drawback is that at this moment there is no program (on PC or phone) that can resize exFAT - so you need to reformat! That is in contrast to NTFS / FAT32 / ext2 / ext3 / ext4 - which can all be resized perfectly - and IMHO NTFS could be a better option that exFAT (for journaling, even if I do not write that much anyway), but unfortunately there is no serious support for it on CWM; ext3/ext4 could also be even better from the Linux standpoint (but not for the usual Windows user that might have problems reading it) - but again is (surprisingly) not so supported by either CWM nor most ROMs

Just got new Sandisk 64GB cards and was having a heck of a time getting them to play nice with Paranoid Android, this guide was simple, painless and most of all, effective. Thank you much for posting this information.

Works with cyanogenmod nightly 2013-02-17 and ubuntu
So I have tried it out and it worked.

Thank you!! Was wondering what I had done wrong with a custom ROM not reading the 64Gb card I had, now it does: )

great to see i helped some people.
ok so software to erase partition is called EaseUS incase this link gets broken in future just google, if im late with reply again in future.

Just wanted to say THANKS
I have been trying to get my 64GB working for days after install wicked rom 5.1 for my Samsung S4, noting worked till I found this post GREAT work and thanks so much!!!!

YOU RULE!
Thanks!! I have only been able to get my Scan Disk Ultra 64G card to work with Perseus kernel and would have to flash it to all Roms then use a hack to swap the internal to get it to work. It was a Pain in the ass and limited my Kernel usage. THANK YOU SO MUCH WHAT A USEFUL POST!! Stick to this plan it works. I have yet to see any other solution. I been dealing with this problem since I had my Galaxy note2 almost a year now.
PS do not use that crappy HP USB format 2.2 whatever program some guy suggested a bunch of malwar garbage I cant get off my computer now THANKS BUDDY Crawl back under a rock which you came.

Thanks for the wonderful help everyone who got it working

i have no idea the swap system, as stock, it already has driver for ex fat but since you changed some stuff it might have ruined that driver.
try your card on another phone with stock rom and same android version. if it works then you dont need to change sd card format, just reinstall ROM on your phone.

Possible and Simple SD problem Fix for WP7 builds

So i tried to install Mango builds on my HD2 after a long ago. Missed WP7!
I installed 3 different Mango builds but all of them said that my SD card is damaged and can not continue.[Kingston 16gb class 4]
Not even some Android builds worked..stuck at boot. [Never had any problem before]
A Format didn't work either with SDFormatter nor Partition programs e.t.c. And i do not have a Nokia phone to unlock the card or something.
The thing is that my card was formatted with 32 clusters, so i went and deleted the whole partition from partition magic and reformatted the card with SDFormatter, automatically it went to 32 clusters again. I went to windows format and selected the default settings on the card [cluster 8000b something] and now everything is working and i can enjoy Mango builds on my phone! WTH?
I also checked some other cards [verbatim,sandisk class 2 and 4] and formatted them the same way and again they are working properly.
I hope his simple fix will help others also and hope i am not mistaken!
Crazy huh?
Sounds interesting, i'll try it with my sandisk 8gb class4, when i'll be back at home. It was behaving like a corrupted after reboot in WP7, even i have tried different roms.

unlock card first with unlock cab + yuki ROM or with old Nokia phone
yeah i noticed this on some marginal cards of mine, didnt effect the speed rating at all but there was some improvment in stability, i wouldnt say its perfect tho, there still some reboots/
top tip, DO NOT move the clusters size to 4K!
well an trully buggered one card up by mistake doing that!
Cluster size doesnt seem to matter. My kingston 32gb class 4 card still isn't recognised (never has been actually). Works fine on android and windows 7
But how can i use my SD cards that never worked with Mango builds? lol

I'm not going to say IMPOSSIBLE! , but it does not make sense.
The first thing you do while installing WP7, is clear the MBR. If the MBR is gone, so are all partitions and their defined cluster size.
There's something else to it...

I totally agree! I had card issues when moving from the HD2 Yuki ROM to others in this forum, and three different cards weren't recognised.
It wasn't that the cards were faulty or damaged at all. I managed to reformat them on my pc after installing the Yuki ROM and using the lock cab to unlock them.

thats a good point, even if you dont clear the MBR manually in MAGLDR the installer does wipe all partitions, which would clear the partition tables and associated cluster size

Still... formating with a X cluster size, might create a 1/0 pattern either at the card begging in case of a quick format, or through the whole card in case of a full format, that WP7 prefers.
I've never had this issue, so i cannot comment.

Unable too see SD card of Partitioning

How did you fix it?
Re-partitioned it back to fat or?
Never tried that option in recovery, does it creates ext?
Well i put the card in nokia phone - the old ones and formatted it there
Any link on how to partition the card right the next time ?
I searched a lot and im still confused
Well I'm searching which format is that sd-ext partition, but can't find. Maybe ext3, or ext4.
Thing is that windows or our phones can't see ext partitions without additional drivers, or custom kernels. Last one is strange to me as android is linux, and ext format came from linux.
Anw, someone please correct me if I'm wrong.
Once I tried to create 1GB ext3(or4 can't remember) partition and rest of my sd card leave in FAT. But windows didn't read it, didn't have time to research, so I format it back to FAT.
You say you were using SE TWEAKED, but which kernel you used? stock?
Iv only on Neo getting this to work once main fat 32 /3 rest of time PC can't read card
To much fk on for little change

Need 64GB Driver.

I bought 64 gb card and it works on samsung stock galaxy s3 rom BUT when i switched to Cyanogen10 mod it started showing damaged card,
I know it is because the stock has driver for that card,
My question is has someone ported or can someone please port the driver from stock and make it workable on custom roms.
Thanks.
exFAT is not and probably will never be supported by CM9 or 10.
Your card needs to be FAT32-formatted to work.
Alright trying hopefully this works and doesnt screw up my card.

didnt work now the phone doesnt even show damaged card, its acting like card is not even inserted.
How exactly have you formatted the card? Windows onboard utilities won't let you format a 64GB card as FAT32, so my guess is you formatted it as NTFS.
Unfortunately CM cannot read NTFS either, you'll need another kernel for that. (And to date none has been released)
Try the HP Usb Format utility to create a FAT32 partition.

Why is this?! Does AOSP not come with exFAT support, it's something Samsung builds into the kernel afterwards?
Disappointed, as I was tempted to try CM, but no 64GB support renders my card next to useless.

FAT32 doesn't mean the card is restricted to 32GB, it means a file can be 2^32 bytes long which is 4GB.
FAT64 (ExFat) has a limit of 2^64 bytes per file which equals 16 Exabyte (1Exabyte = 1024 Terabyte)
It's possible for FAT32 partitions to be as large as 8 Terabyte, which is roughly 1000 times the size of harddisks when FAT32 was released.
Windows, for some stupid compatibility reason with a 12 year old operating system (Windows 2000) does not allow to format FAT32 partitions to a size larger than 32GB, hence the usual confusion.

ExFat is patent-encumbered, meaning every distributed binary copy of Cyanogenmod would theoretically cost the developers the license fee.
(At least for US-based downloads, most other countries see software patents as what they are - ridiculous and unenforceable)
Furthermore -and a very big issue- is the instability of the exFat code for GNU/Linux (and by extension, Android) which causes data loss, corruption and other negative side effects.
It's highly recommended not to use exFAT with Samsung-firmwares either.

i used easeus partition: i deleted partition first and made new one with fat32 file system,
which didnt work, after that i deleted the partition again and formatted using stock galaxy s3 rom and it works again but limited to stock rom only like before.
atleast the card isnt dead.

Thanks, though I realised this - the whole reason I need a 64GB card is to copy movies onto there, because I travel a lot... many of them are over 4GB, which is the issue I have with using FAT32.

Maybe I should look at ext3 instead, though then I'd have problems putting it straight into my Windows machine. Though, exFAT has been 100% stable for me so far.

Ok that is a problem for FAT32. You didn't mention it so I assumed you mistook the 32 in FAT32 for 32GB as many people do.

Since you should never need to remove or directly access the card (MTP mode or File transfer through 'Samba Fileshare' App) that should be a solution. For your own computers, you could use the following driver:
http://www.fs-driver.org/
It allows read-write access to EXT2. EXT2 being EXT3 without journaling support (and thus fully backwards compatile) that could do the trick.
Pententially you'll need to re-enable the journal again through tune2fs on the Smartphone after having used an EXT2-driver. Not sure though since the journal is only relevant until a clean dismount is made.
You should however also be able to load the NTFS-module in the kernel or recompile the CM10 kernel with the required options.
If you need to plug the SDcard into your computer a lot, that may be the only solution until Gokhanmoral is back.

[Q] Looking for a Rom that will work with Exfat 64GB sd card and is themed

Please don't flay me alive, have searched the forum, net, front garden.
Very new to Romming my SG2, but had settled on cyanogen 9, as I loved the themes and the speed, battery etc.
All was great until my 64GB sd card stopped working, which after looking up I believe is a known issue with Exfat and CM. After 2 days of trying every way to format my sd to fat32, and having had no joy it seems that my only option is to switch from cyanogen altogether. With that in mind, is there any way to flash a altered sammy rom that is themeable, have had a look through the roms, but not been able to find a rom that is exfat compatible and also themed to black and white. Any ideas folks? Any help is much appreciated. Maybe it's not possible.
I think ExFAT was cut away in ICS.
Connect the SD card to a Linux machine and rewrite the MBR and then format to FAT32.
Cheers for the quick response, unfortunately not got access to a linux machine, am stuck with a laptop, so can't use a live cd even, and the laptop seems to have issue with running a live image from a pendrive. Any other way to achieve this. tried Format /fs:FAT32 in cmd through windows, but fails format every time, tried the hp app, and it only offers me ntfs and exfat. Really would like to keep cyanogen if possible as it's great.
64GB exFAT isn't supported in any ROM, although FAT32 will work.
Will keep trying to find someway to format to fat32
worked it out, seemed Although I was formatting the sd to fat32, the clustersize was wrong seems it need to use 32kb clustersize, which I achieved using EaseUS. Thank gawd.

CWM 6.0.2.7 - 64 GB ext SD card, Unable to mount / format / access, etc.

Hi there,
I have the following issue and hope to find somebody with a solution here in the XDA-world...would be great.
Of course I did some searching before I post here, but the results are not sufficient for me...
I am using a 64 GB external SD card in my Samsung Galaxy S III since a few days. Before I put data to the card, I performed a format via the phone itself. The access works great - I can use all my files when I use the phone in normal operation. (with Ultima Rom).
Today I downloaded the latest ROM release and wanted to flash it via CWM 6.0.2.7 and I encountered a problem - I cannot access the external SD card in CWM recovery. It simply say´s "Can´t mount external SD".
Why is it? Any solution proposals? I used to have a 2GB card and the installations worked fine with CWM here....
Is it a wrong formatting probably? Or the size?
Thanks for any suggestions!!!
You should do some search before post, but since you are here, I give you some briefly information, but you have to search more details yourself.
1. 64 GB sdcard is formated in exFAT file system which CWM recovery doesn't support it, that's why you have problem with 64 , but OK with 2GB sdcard. (Some latest recovery has now support exFAT I think )
2. Solution, format your sdcard into FAT32 file system, or change to 32 GB sdcard because unless you have countless files or blue ray movies otherwise you won't need 64GB at all, that's what I did, I had 64 and change to 32 to avoid any kinda potential problem

1. Use PhilZ Touch recovery (based on 6.0.2.8 - I think 6.0.2.7 was also very buggy - and with a new Samsung kernel supporting exFAT).
2. Format as FAT32.
I am currently using the 1st approach, but keep in mind that many ROMs (mostly based on CM10 stuff) still have a huge bug where the exFAT partition is not recognized but instead some stuff is written to the first sector - when that takes place just put the exFAT card in a SD-reader in Win7/8, reject any suggestion to format it and then from the command line run CHKDSK /F Letter:
Thank you!!!
Thanks a lot to both of you!!! It worked out! :highfive:
I also managed to search for "how to format an SDCard to FAT32", no problem.
To be honest I also had a look for a possible solution like you suggested prior to my post --> I just was not confident that these suggestions will solve the issue since I read many times "tried - but no success"...
I just wanted to be sure, coming back from work, not to spend hours to solve it, if you already have "the one working" solution available. Once again many thanks - I really appreciate this community, even if its my 2nd active post...
