[Q] SD Card File System - Galaxy S 4 Q&A, Help & Troubleshooting

I just got my 32GB card in the mail. What file system should I use? FAT32, NTFS, ExFAT?
Will the GS4 even recognize NTFS or ExFAT? I'd like to be able to put some big files on there if I can.
I'd like it to be interchangeable with my Windows PCs so Linux file systems are not an option for me.

What card did you get? I'm concerned to buy another sandisk card, had bad expirience with them 2 of 32GB got corrupted forever, on my old S3, dunno if was just a bad batch of what...

Confirmed. ExFAT works. If we're ever graced with CM10 on this phone will that be able to read ExFAT as well?
The card I got is a Samsung class 10 32GB from amazon.

Officially? Very, very, very unlikely.
Unofficially? Probably.
exFAT is patent-encumbered, and there's (to the best of my knowledge) no (currently usable) open-source implementation of it. So, CM10(.1) won't support it if you use the official CM kernel. However, it's likely that there will be kernels that *do* support exFAT that you'll be able to use with CM10.1, but doing so means that you're on your own in terms of CM support.

im wondering about ntfs, will that work? just downloaded a file thats 4.3gb lol

64GB MicroSD Card - The how-to guide!

As you all hopefully know, the Note Can take up to 64GB MicroSDXC cards. But, what you may not know is the trouble that with comes with getting one to work. Its actually relatively simple When you know how to do it. l spent hours tonight trying to do it.
Originally the sd will probably be in the NTFS format created by Microsoft, which is understandable since its the biggest OS on computers.
Upon entering your SD onto the device, you should see that it wants you to format it. This is due to android not supporting NTFS. The only structure it supports is FAT32.
But, here's where your options come in! You have the choice of either making your device NTFS compatible (Note that this requires root), or reform making the storage device to FAT32. As my device is not yet rooted to test the NTFS support, l will only go over the reformatting process. Unfortunately, since I'm a new member I can't post links. Therefore, you'll need to trust google to guide you to what you want. But if you want to use the tool I used just Google "Kioskea HP USB Disk Storage Format Tool"
Disclaimer: I take no responsibility for any damage that you Cause to your device, computer or SD card while carrying out this method. It is your own decision to do this. This method should cause no harm to any system health, but, as with anything on a computer, errors can occur. Also, take note that the more you format something, the shorter its life will be.
Insert your SD card into the computer to format it. To format to FAT32, you will need to download a third party partition program, as windows withdrew the ability to format to FAT32 in an attempt to push more people on to NTFS. Only storage mediums with FAT32 as their default can format to it.
Once you've downloaded and installed the software, load it up and select your sd card and FAT32, as well as quick format then start. You should then insert it into your PHONE as the tablet doesn't seem to do this next step correctly. When inserted into your phone, it should say that the sd needs formatted. Do this then eject it and transfer it to your tablet and say yes to the dialogue that appears. And that's it in a nutshell! This can be applied for every android device possible.
Users report the newer note 10.1 updates will format 64gb cards into exFat which will allow for files bigger the 4gb (like HD movies).
Yes, i can confirm that if you update to the pulled ota update firmware, your tablet can format the 64gb sdxc to exFat and be read.

Sandisk 64Gb microSDXC cards comes preformatted with exFAT and not NTFS.

I am using sandisk 64G sdxc card in my N8000 (Hong Kong version N8000ZSALI1 firmware) which natively supports exFAT format. It is fine so far. But I do not dare to copy large file from USB cable via Kies. I take out the card and put into SDXC card reader for large files copying.
Hi, I have some questions:
- What different between "HP USB Disk Storage Format Tool" and the Windows built-in format tool?
- Why your GNote 10.1 cannot format the SD card?

@Tubgirl my one came formatted with NTFS, rather than exFAT. So, I had assumed the rest were like this. It's strange that mine exFAT. :s

@Itchiee I'd seen reports of updates being able to support 64GB cards but that's all I was able to find. I only just got my Note 10.1 and it says on both the internal update and update via Kies that my tablet is up to date. Although, I am from the UK that may be why. I assumed my tablet was rolled out with the latest update. I tried exFAT on my tablet and it refused to work and was throwing the same error's at me.

@vndnguyen I recommended the "HP USB Disk Storage Format Tool" as compared to the standard Windows one as Microsoft pulled formatting support for anything except exFAT and NTFS. The only time Microsoft will let you format to FAT32 is if it was the native of that device, such as a flash drive. So, the difference between the two programs, is that the "HP USB Disk Storage Format Tool" can format to FAT32, as where Windows cannot.
I have just ordered a 64 gb sandisk android sdxc card, if i am not to bothered about transfering large files, is there much difference between using exfat and fat32?

This is because the native format of 32GB MicroSD cards and below were FAT32. Like I said, if the device is native FAT32, then Windows will allow a format of that.

Sorry for not replying in my last post. I never seen your comment. There's some slight differences between FAT32 and exFAT. The main difference a common user should know is that FAT32 can only hold, and transfer a maximum of 4GB, as where exFAT does not have a size limit. That's why it's the "preferred" method. But, FAT32 is more popular as it's been around longer and is supported by more platforms than exFAT. If you want to know more about the differences, try a google search. Unfortunately I can't post links just yet to help you out with that. But, I'd recommend trying the exFAT wiki page. The stuff you'll find can get fairly technical. Just a heads up.
thanks for your reply, the sandisk card i am getting says its been made for android devices, will that means its probably already in the exfat format when i get it?
Would you know if the below card which i have ordered would probably work straight out the box?

This is the one I got and I had to format on my Defy first. Then my tablet excepted it, for now I can only put movies, photos on. Any apps you want on doesn't work as of yet which was a big let down for me.
This appears to be the same one that I ordered. Mine came as NTFS but it may have just been a hiccup for mine as everyone else is apparently exFAT. One thing I also noticed is that the page says it is both class six and class 10. Just to clarify - It is class 10.

Yeah some require root. I tried some today, as well. They don't work due to the memory config. Seems to be happen to all new releases, as if they're trying to block stuff like that. With all the trouble Google and manufacturers are going to to stop us rooting and stuff like that, Android will soon be as non-combustible as iOS!

This is because Samsung claim that their Note 10.1 can support exFAT. In reality, the support for it doesn't work at the moment. What you will need to do is reformat it to FAT32, and it should work. If it still doesn't work after this, put the SD into your mobile phone then use the reformat option on the phone. The reformatting does not work on the Note 10.1, so you can't reformat it on that.
Let me know how it goes.

when i put the sd in my laptop,the 2 options that let me choose is ntfs and exfat.how can i reformat it to fat32?

[TIP] the JB leak comes with proper exfat support.

After finding exfat files in the filesystem I formatted my external sd as exfat and the phone recognized and used it with no problems.
I am currently backing up my internal sd card to do the same
Note doing a format from storage settings still uses fat32 so format the card in a computer or unmount the card in the phone and use a adb shell to run
mkfs.exfat /dev/block/mmcblk1p1
after backing it up since you are formatting.

secure_format = enable
discard = enable

It may be possible but I am not going to worry to much especially since I need to leave one as fat32 or else lose most CWM functionality since it doesn't support exfat.

of course it would, Microsoft created exfat.
I'd love to switch to exFAT for its advantages, but I just know if I switched to it, I would have to go back to FAT32 when I use CyanogenMod, namely due to the fact that you have to get patent licenses and crap from Microsoft to be able to implement exFAT, which I assume Samsung must hold so they can use it on their phones and TVs.
What we really want is MTP fully working on Linux and for the internal and external SD cards to be in EXT2/4 or something like that, and then it would keep both Windows and Linux users happy and we would have better file size support and performance.
That's my 2 cents.

I know that would be great if it happened. I know before I realized exfat worked I had mine ext4 and used a app to mount it but it had little drawbacks that this native support fixes.
Plus now I can connect my digital camera to my phone via OTG since it has a 64GB sdxc card that uses exfat which is another major plus. I always hated being out and not able to get my photos off it and passed out to other people until I got home and to a computer.

[Q] 64gb SDXC card, how should it be formatted?

Ok, so I've just bought a Samsung class 10 SDXC UHS-1 card. I'm about to put it in the phone and then I read all about people having problems reading files, and wanting to download something to allow it to be formatted to fat32, etc. Could anyone please throw any light on this, as to how it it best formatted, and to what fat type, and possibly help me to understand why these people are having issues?
Personally I would have said let the phone format it, seeing as it's going to be using it?
1. Put it in the phone.
2. Press "Erase everything on SD-card".
3. ????
4. PROFIT!
No need to worry about formatting, the stock kernel only supports FAT32, and I believe EXT3 & 4, but you don't need to worry about those.
Some people have problems because they buy the cheapest 64GB microSD card available, and you know that cheap card = cheap NAND, which causes corruption of files and random unmounts.
You mean exFAT? That's what the phone formats it as, and the PC does too.
I am using exFAT because I put 4GB+ files there. FAT32 can't support that.

I did not know it had ExFAT, but I just put the card into the phone and pressed "Erase everything on SD card".
Well, I've put shed loads on it and no problems so far, and in my card reader I get up to 16MB/s write, so it's all good. I guess problems are just down to the people who buy cheap knock-offs?
I didn't even do a format on my SanDisk 32gb class10.
I just popped it in and it works.
Think I might format to exfat though so I can store larger files.

I got an S4 yesterday (USD 665 here in Muscat for the unlocked 16GB model) and put in the 64GB card I used before on Note II. It's formatted as exFAT.
On first power on, the phone complained that memory card was damaged and needed reformatting. Bummer! The S4 doesn't support exFAT???
I ignored the error and continued setting up the phone. After a few minutes I checked Settings->Storage and was given the option to mount the memory card. I tried and it mounted without any problems! Phew!
FAT32 is the way to go. Later, if you install a custom ROM exFAT won't be supported.

Not if you have files larger than 4GB, like full HD movies. FAT32 doesn't support files of that size.

I can confirm that my rooted i9505 (jfltexx from Vodafone Ireland) does support exFAT directly. I have a Samsung 64GB card which came preformatted with exFAT and it worked. I later formatted it directly in the phone and it was exFAT again. No problems whatsoever.
If you want to install a new kernel, however, you might get into trouble. faux123 wrote the following in his thread http://forum.xda-developers.com/showthread.php?t=2273437 for the new faux kernel:
"NOTE: This kernel DOES NOT SUPPORT exFAT formatted 64 GB SDCards! In order to use 64 GB SDCards, you need to format it to NTFS, then use NTFSMount from Play Store to access your 64GB SDCard.
(This is due to LACK OF SOURCE CODE from Samsung/Microsoft for exFAT. Samsung licensed Microsoft's CLOSED SOURCE exFAT implementation. But Samsung under agreement with Microsoft DOES NOT release the source code and therefore we CANNOT build any support for exFAT formatted 64 GB SDCards)"

[Q] exFAT external sd card problem...

I have the strangest feeling this has already been answered somewhere...but i've scoured the internet and havent found much of anything on the topic. I've read some mixed statements saying ppls sgs4 see's an external sd card formatted as exFAT, others say it isnt working for them. I've figured out a way to get the hardfloat Kali Linux ARM gui terminal working and all applications installed running in a chrooted environment...however the image size needs to be a minimum of 6gb to install all programs. I'd like to go with 8gb just to give it a little play. I have an SGH-I337 (AT&T) and am rooted, i've tried stock rom w/ stock kernel, stock rom w/ KTweaker kernel, said it supports exFAT but did not work. Also i've tried Cyanogenmod 10.1, but havent tried the KTweaker kernel w/ cyanogenmod yet. After formatting the 16gb microsd i have to exFAT and inserting it into the phone it states "Preparing SD Card"...and immediately says "SD Card is safe to remove". Anybody have any insight as to how i can get around this 4gb filesize limitation? Any input will be greatly appreciated. Thank you.
Here's the deal.
All cards 32gb or less (SDHC cards) come formatted in Fat32.(Part of SDHC spec) This includes a file limit of 4gb max for a single file.
All cards 64gb or more (SDXC cards which the S4 supports) come preformatted in exFat (Part of SDXC spec). This does not have a 4gb file limitation.
The stock Samsung / AT&T Firmware supports exFat. (I bought a 64gb SDXD formatted with exFat and plugged it in and worked right away). Most recoveries do to. (TWRP does at least).
However, I flashed CM10.1 onto my S4. CM10.1 does _NOT_ support exFat. Initially I backed up and reformatted my card in Fat32. Angry with the 4gb file limitation (I have many 720p and 1080p movies over 4gb..) I actually took the microSD card out, used a adapter and hooked it up to a Linux system (Ubuntu 13.04 in my case) and used gParted to format the card to EXT4 filesystem. EXT4 is a filesystem most Linux machines use and support natively. This is actually the filesystem most newer Android device use for their internal SDCard / Data partitions! I popped the card back in, CM10.1 reads it perfectly! And I was able to copy files over 4gb to the device!
So its not a hardware thing since the S4 is SDXC compatible. Just formatting / partition time issue.
I greatly appreciate the breakdown! However i do have a question, since the sgs4 supports exFAT, why does it not see it after i reformat my 16gb to exFAT? Is it because it is an SDHC and not an SDXC? Also, does the type of recovery you have installed alter what filesystem types are recognized?

No problem!
As far as the spec goes, if it's formated in exFatand its SDHC it should still read it fine. Filesystem is just a filesystem. The spec just says what is used by default on cards.
One possible issue though, did you format your card in your phone? Sometimes the odd way these work the SD cards like to be formatted in the phones themselves. It worked formatting from a Computer for my ext4 case, however that does not work for all cards/phones/filesystems sometimes.

I've tried formatting from phone, 3 different computers (one computer running Debian), cfdisk command line as well as gparted, also window's format utility. It seems though nothing is working however after going to Cyanogenmod 10.1 last night and formatting the external to ext4 the phone only displayed "Reading SD Card" then "SD Card is blank". It works perfectly fine whenever the phone formats it, it just doesnt like any other type of filesystem. It is a polariod sd card which gave me issues in the past. Hopefully i can get this resolved and post more on it. Probably just something small i'm missing :/
Anyways, thanks a million on the input!

[Q] Doesn't read Ext4 neither NTFS for the sdcard, wtf?

Ok, android is supposed to be just fine with Ext and NTFS right?
Well i've got S4, kitkat 4.4.2 and 64GB original super fast microsd card and guess what, i formatted it first Ext4 then NTFS because i needed more than 4GB files and for both it says "SD card is blank or has unsupported filesystem."
both times formatted under linux desktop PC
the default formatting from the phone seems to be either FAT or exfat but files over 4GB can't be written. (exfat is supposed to do over 4gb right?)
So, what i'm doing wrong?

Official Galaxy S4 doesnt support NTFS (not sure about Ext4). but there are some custom kernels that can deal with NTFS.
I found this on wikipedia:
exFat advantages: File size limit of 16 EiB–1 byte (limited by volume size), raised from 4 GiB−1 byte in a standard FAT32 filesystem.
so I guess yes it can handle files more than 4GBs, I haven't tried it myself.
Use the official SD formatter tool, it formats cards with 64 GB and larger using the exfat system.
just google: official SD formatter

Official Galaxy S4 doesnt support NTFS (not sure about Ext4). but there are some custom kernels that can deal with NTFS.

With the build in formatting tool is what I use to format it, but then I can't write a 30GB file
in the file size limit you mention " File size limit of 16 EiB–1 byte" what's EiB?

If it's a cheap and therefor most probably fake SD card this can also be a problem. Most cheap 64GB cards do not have the advertized capacity.

I Always format my SD cards using Minitool (PC app). Never missed a beat.
If this doesn't work I still think it's a fake SD-card
well it's not, thanks for getting the thread in the wrong direction though!
so does the default bult-in android formatting do FAT or exFAT? It doesn't seem to be possible to tell from the phone?
So, seems like the only way forward is to format it in exFAT?

I am pretty sure it will only format in the style it was originally eg. Original setup of fat32 it will format fat32, if EXfat it will format EXfat.
Ext,1, 2, 3, 4 are all native to android (Linux) so ext4 shouldn't be an issue.
When I formatted my 64Gb card sd formatter did not format it to EXfat I had to do it manually. Please not that windows Xp does not directly support EXfat you need to manually install a patch and then manually format the sd card via cmd window
You'll have to confirm the command but it's something like
Format x: /fs:exfat
This is what I had to do on my old Xp box to do the job.

Oh btw ntfs is proprietary file system to micro$oft and technically it's closed source, but I read somewhere ages ago someone managed to hack something together that does work

formatted it to exfat and it works now
so for anyone else that wonders here is the summary of what I found
the android on Samsung S4 reads only FAT and exFAT on the SD card.
NTFS and Ext4 it does NOT recognize.
by default it formats FAT
I had to format it exfat on a PC
works now, still haven't tried with files over 4GB but shouldn't be a problem
