[Q] exFAT external sd card problem... - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

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!

As far as I know there aren't and posts saying it supports it but I've used TWRP with exFAT, Ext4, and FAT32 formatted ROMS.

roms not reading 64gb sandisk sdcard
I have the 64gb sandisk ultra class 10 sdcard... and it flat out works in stock... even when I recover. But doesnt work atall using wicked rom and a couple others. ExFat is the reason... those roms dont support it...

You can use this kernel to get exFAT support on custom ROMs such as Cyanogenmod:

[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)"

Help with 64GB SDcard

Just got a SanDisk microSDXC 64GB card from Amazon for my Galaxy S4. I don't want to mess anything up, so I've got a few questions.
Are these cards formatted with exFat? How can I tell? Do I need a special kernel to have it work? Will the stock kernel work?
Should I format it from within the phone before use?
Any other problems/concerns I should have before I copy all my music and ROMS over to the card?
Thanks in advance,
Foulwx...in Atlanta tonight where there really is some foul weather.
I recently purchased a 32GB SanDisk Ultra, and followed the instructions at these two links, for moving apps to the sd card:
http://forum.xda-developers.com/showthread.php?t=2142844 - mini partition tool guide
http://forum.xda-developers.com/showthread.php?t=2285221 - link2sd and foldermount
If you have some way to connect the card to your PC, the mini partition tool guide is really easy to follow. If you don't plan on moving apps to the card, you could just toss it in the phone and format it there. I screwed up the partitions a couple of times on my own (formatted the card 5 or 6 separate times, trying out different filesystems and partition sizes), before I found the mini partition tool guide, so I don't think there's much chance of permanently ruining the card.
If you formatted the card into fat32, then it would be more compatible without modifying anything on the phone.

You can connect the microSD to your PC to determine what format it currently is. If you stick in the phone, it'll format to exFat. The exFat format can be recognized by the stock kernel as well as the agat kernel and the ktoonsez kernel.
I have the same one. Just put it in my phone and went from there. Guess it auto formats it to exfat that way.
I flashed bluKuban and had to switch to agats kernel to see it. But otherwise works well.

exFat can have files over 4gb.
I killed my sandisk 32gb ultra card ...created the fat 32 partition and then the exfat and it won't be ready by the phone at all. When I put it into the computer it shows it only has 30.6 MB...I'm unable to format it through windows or with another app. Any help would be appreciated

Its not being read by the phone it doesn't even mount..
I'd try plugging it into the computer and running a partitioning program. It should see the card no matter what. Partition it to whatever format you want.

Theres one computer where it sees it and I connect it through an HP printer that had an SD slot.. Windows shows it as 30.6MB and asks me to format it but the format fails. I tried SD card formatter, HP USB disk tool..I don't know what to do
OK, I loaded all my music, pictures, and roms onto my 64SDCard from my laptop. Windows says it is exFat. Booted and seems to work fine.
Then I went into OUDhs recovery to try and make a nandroid. It can't mount the external_sd. Suggestions? Do I need a different recovery or kernel? I'm on the stock kernel.
Thanks again.
Edit: I installed TWRP 2.5.0.3 and it worked fine, I think. I haven't tried a restore yet.
I finally gave up with exFat and, after some research here on XDA, used Mini Tool Partition Wizard Home Edition to format my SDCard to fat32. I just made a Nandroid with OUDhs recovery. Hopefully, everything will continue to work OK and I don't need any 4GB files on my card.

SD card support

As the 'instructions' and the online help are no real use, i am throwing this out there....
It states that she Shield supports up to 256gb mSD cards, I have a 64gb Samsung XC card, the shield seems to know it is there as the 'Mount SD Card' option is not greyed out, but it wont mount or format the card
I have formatted the card NTFS as suggested in the online manual
The card works fine in a Galaxy S4
My 32gb card works fine, but is too small.
Any ideas?
Dale
I have never gotten the shield to format a sdcard. You will need to download a third party tool to format it fat32, as windows won't let for format any partition over 32gb fat 32.
Depending on the format options fat32 can support up to 1 or 2 terabytes

If on Windows, you need to format it using this:

Windows will only format FAT32 up to 32GB using the built-in utility, even though FAT32 supports up to 2TB.

Thanks for the links, i have never visited the geforce forum, the link i posted is from the actual instructions included in the online help built into the device.
If the card needs to be formatted as anything other than NTFS then they need to update the instructions, as i assume thats where most users would look first..

I argee, and I have had trouble getting my 16gb sdcard to work in it, but my 8gb works fine.
16gb is a sandisk sdhc class 4
The odd thing is, the shield does something to the card, if i put it back into the Galaxy S4 after removing it from the shield, the S4 says its damaged and needs to be reformatted. It then reformats it and mounts it ok.
Really need more than 32gb in the shield....
I got my 16gb microsd working. I noticed that my 8gb has a gpt partition structure and the 16gb had a mbr structure, after converting the mbr to gpt on the 16gb it works.
I popped in my 16GB MicroSD that I use for my SuperCard DSTWO and it read it without issue. I copied some ROMs from it and to it, worked perfectly.
I have now converted my 8b working sdcard from gpt to mbr and it stopped working so i will change it back to gpt.
Posted in other threads about this stuff. What ive experienced.
SanDisk 64gb Ultra*microSDXC™ UHS-I fails to mount in any format other than NTFS. Trying to mount otherwise results in loss of data and formating. Under NTFS format that file path is something ridiculous than can't be seen by some apps rendering the card basically useless. The card works fine in all other devices in several types of formating.
I have a 16gb of same brand and speed rating that mounts fine under FAT32.

Is anyone having issues ( with the save path etc...) when using 64gb formated as FAT32?
Another post in that thread on the GeForce forums is that it does not support unicode file names.
The main difference I know of is that FAT32 does not support single files over 4Gig in size, NTFS does.

NTFS is also a journaling filesystem and has a few more inbuilt security features (which I see as pointless for the filesystem itself). Journaling won't actually do any good for the longevity of the SD card, its extra read/write cycles which are already limited enough on an SD card.

[Q] Need help formatting SDXC External chip.

Hello everyone,
Recently, I flashed a Lollipop ROM to play around with it. This isn’t about the ROM or the Android release in particular. It’s about filesystems.
While Lollipop worked perfectly fine with my external SD, the OP mentioned reformatting the SD Card as a different filesystem to play nicer with the new release. The other benefit of doing this would be support for >4GB file size, which is what I want. I've meant to do this for a while, but I've been too busy.
I’ve since reverted back to 4.4 while I wait for a more preferable Lollipop release to bake, but I still want to reformat my external SD. It is 64GB and I’ve attempted to reformat in TWRP, using a USB SD reader using OS X Disk Utility and a built-in reader using Windows format tool.
Nothing works! TWRP says it formats successfully, but everything is intact. Windows gives errors, OS X can’t remount the drive and finish.
What’s going on here? FAT32 sucks and I want to change it. Is it a protection on the chip?

Cards over 32GB in size are supposed (as per SD-alliance standards) to be exFAT, stock Samsung ROMs WILL format those AFAIK to exFAT. With the card inside the phone no other formatting option (than from the ROM itself) will work. With the card taken out and placed into a decent card reader in Windows 7 or newer you should see the option to format it to exFAT, and all decent ROMs should now work with that (Samsung stock-derived ROMs work best since they have a very solid exFAT driver, CM-derived ROMs have been very ****ty in the past in this regard).
Oh, and one more thing - questions should go to Q/A!

Micro SD card wont be mounted by Samsung Tab a6

So I have a Samsung Tab a6 7 T280 wifi and I've inserted a MicroSD card (128GB). I've done this with the stock os first and I just got the message card can be removed safely. and it wouldn't let me mount it.
Now I've installed the Tinker V5.1 Stock Rom over it and it still happens. (wanted a faster os on it).
I can reformat the card with twrp to be ext4 or exFAT and it doesn't change a single thing. if I insert the sd card I get a quick preparing card and then instantly the message card can be safely removed. clicking on mount sd card in storage from settings doesn't do anything except prompt same message.
I'd try a different sdcard.
Okay, so I hope I can help, I have the SM-T280, I do not use Tinker ROM, instead I debloated my stock ROM and use an SPA kernel by @_mone. If you're trying to extend storage to your tablet, you'll need to use a PC to partition the SD card two PRIMARY partitions. I used on Windows MiniTool Partition Wizard (free), and I used a FAT32 partition and an ext2 partition. With the stock ROM/kernel I had problems using ext4 or extFAT which didn't make sense to me but it is what it is, and I used the app Apps2SD to handle all the work.
The main thing, you need to make sure your SD card has TWO (2) PRIMARY partitions.
Good luck.

What about the Sizes? As in one partition 60 GB the other one also 60 GB ? Or the fat32 partition 1 GB and the ext2 the rest?

FAT32 is not for large capacity storage. Use exFat. There isn't much point in having such a large ext2 partition. It's incompatible with media transfer protocols unless you use a Linux system.
This device fully supports exFAT. I use a 64gb sdcard no issues.

I wouldn't think so, I'm sure it supports 128gb cards.
Just partition it into to halves. First partition exfat. Leave the other unformatted and see what happens.

partitioned into a 40 GB exFAT partition and left rest unpartitioned. Didn't change anything. if I pop it in the tablet I get a short preparing sd card notification then immediately an SD card safe to remove notification...
I'm really confused by this. The tablet is new so I doubt that it's broken but I don't know. Do you know if there's a way to check any kind of logs on Android like dmesg on Linux as an example to see what happens with the sd card?

Nobody can lend one for a few minutes? Or try the card in someone else device?

So I have a Samsung Tab a6 7 T280 wifi and I've inserted a MicroSD card (128GB). I've done this with the stock os first and I just got the message card can be removed safely. and it wouldn't let me mount it.
Now I've installed the Tinker V5.1 Stock Rom over it and it still happens. (wanted a faster os on it).
I can reformat the card with twrp to be ext4 or exFAT and it doesn't change a single thing. if I insert the sd card I get a quick preparing card and then instantly the message card can be safely removed. clicking on mount sd card in storage from settings doesn't do anything except prompt same message.

According to Samsung, the T280 will support a 256gb SD card BUT I know from experience that SD cards over 32gb can be VERY touchy. If you use a PC to remove all of the partition and then let the tablet try to do its own formatting and it still doesn't work, I'd say you have an incompatible SD card. That doesn't mean the card is bad but that it just won't work in the T280.
As an example, a Samsung EVO+ card (which can be found on eBay for $30) will probably work while a "no name" card from China, probably won't.

I always use Samsung EVO cards and they always work perfectly. Price per GB they are very reasonable too.
