I have not been able to find a way to mount in the external card slot an sd card formatted (under linux) with an ext4 file system on it. I have a rooted P600 tablet running kitkat, with the external sd card fix. I'd be grateful to learn it's just plain impossible, or to have a pointer to a solution.
So that is impossible, too. Like Ntfs.
Thankfully we have ExFat.
"True" custom roms may change that. There is one for the p600, and an early stage Cm11 for the p605.

Hey guys total noob here to android and flashing ROMs. I rooted my phone and flashed to TuchMi S3X 5.0. First installed 3.0, then went to 5.0. In both builds, my SD card wouldn't mount, i'd get a message saying "Preparing SD card" in the notification bar, then "SD card is safe to remove." When attemping to mount through Settings, nothing happens, and I can't mount in recovery either.
I've tried reformatting every which way I can think of, but still no luck. The same card worked fine in stock.
Any tips? I've searched all over the place but couldn't find anything pertaining to TuchMi S3X and external SD cards not mounting.
So i've determined that the issue is with the exFAT file system. If I format the card in FAT32 it works fine, but this is a 64GB card, and I want to use exFAT.
If i let the phone format the SD card when it is unformatted, it uses exFAT but the card STILL isn't able to be mounted...do I need a custom kernel or something?

So bottom line the card still showed 64GB and worked as long as it was FAT32?
Fellow n7100 owners and Devs. I have a large 64GB NTFS formatted SD card, for various reasons I need to use NTFS and not FAT, FAT32 or ex_FAT.
For some time I have been happily using the Paragon NTFS mounting program to automatically mount my external SD card on /storage/sdcard1 and it has been working well. That is unit I upgraded to a ROM that uses Android 4.2.X!
The reason for this seems to be that Android 4.2 breaks Dalvik-apps that mount file systems to be shared with other apps. [email protected]!!! See the post below for more details.

My questions is... Does anyone know of another way round this? I need my NTFS formatted card mounted as /storage/sdcard1 else it breaks a lot of other things for me.
Are there any 4.2.x roms that have been patched to cope with this change? My ROM of choice at the moment is JellyBam and I am currently stuck on version 4.1 because of this limitation. I could be persuaded to move to something else that would allow me to work around the issue.
Anyone????
Many thanks,
I downloaded & used a file called fat32format.exe on my 64 GB SD card. It was the only way I've found to use the card in my Note 2 GT-N7105 on a custom Rom.
Hello everyone, I know this thread is already present and I also red the info regarding with it, but it seems my problem is something I can't solve with the help of those previous instructions. I have an I idea how to solve it but I'm hesitant to do it because I don't know if it works, and I kinda scared to do it because I don't want to buy again another SD Card if ever the present one will break.
Problem: I have a torrent app in my Note II and I liked to use it always because it downloads fast, but the problem is that whenever I want to download files that is more than 4GB in size, I always receive an error that the file I want to download is to big for the file system; (file system limit exceeded), and I learned that this error occurs when my storage system is FAT/FAT32, then I read a thread in this forum that this will be solved by converting my SD Card's file system to NTFS and use Paragon NTFS Mount app so that my NTFS Card will be accepted by my phone, alas I did as what was instructed, converted my SD Card to NTFS, mount my card to storage/sdCard/extcard <---Created another path as it was said that using the default path would make it not work. But when I re-started to download files it fails to me again, the same problem encountered (file system limit exceeded). I even converted my SD card to exFat because I heard that this can handle large files, more than 4GB but also to no avail.
Solution(not tested yet): I am planning to make 2 partitions in my SD card, one partition would be fat32 and the other would be NTFS, and use also paragon app, so that when I insert my card to my phone, the phone will mount the FAT system to the fat32 partition and leave the NTFS partition alone and not be used.
Does this method of mine will work? Are there any ideas aside from what I had in mind that will also help me solve my little problem. I know that this problem of mine is not that big, and I can just refer it to other threads and the google but I want to know from the pro's and OP's here if my method is possible.
Thank you!
Kudos to all!:good:

You need to define a mount point like sdcard0 is internal sd sdcard1 is external sd fat32 partition sdcard2 as the ntfs partition which is really hard to do on a samsung based rom (even windows doesnt recognize the second partition on sd cards ) you can format the sd to ext3 or ext4 it's the best possible solution

I see, too bad, but thanks any way. Does the procedure in formatting my sd card to ext3 or ext4 is the same as when I format my card to fat32 other system, or would you use a program to do it.
Why are you using Fat32 or NTFS just format the SD card to ExFAT. No size limit and compatible with Note2 & Windows
I think the problem you are having is due to the torrent app you are using, it might be trying to use the internal phone memory as a temporary location for the file you are downloading. Try changing your torrent app
(I had this problem with the official utorrent app)
For some reason my ext4 formatted 32GB MicroSD card is not being recognized from my file manager. However, when I boot up in TWRP recovery, I can see the SD card and its contents.
This morning was the last time I was able to browse my files in the external SD partition. I downloaded Spotify, downloaded some songs for offline listening and that is when I received an error message that I was out of disk space. When I checked my internal storage, I still have 4GB left but the external SDcard is nowhere to be found.
Is there an android utility I can use to restore my access to the SDcard paritition?
You need to format it to fat32, I had to do the same once rooted. You will need a utility on a pc to format it. Eric

Confirm your kernel is supporting Ext4 , some custom kernel doesn't.
Hi,
I'm using ROM CM 10.1 nightly 2013-05-01. I have downgraded to CM 10.1 2013-04-01 nightly and even formatted the internal storage then flashed back to stock ROM.
Same thing. The stock Samsung ROM says I have a blank external SD card. CM 10.1 ROM says there is no external SD card.
However, when I boot to TWRP (2.5 version) recovery, I can see the external SDCard just fine.
I would love to go back to FAT32, but need the ex4 because I have a Linux installation that requires at least 6GB partition to work.
My setup with ext4 has been working for about a month, up until yesterday. I have no idea why this happened all of a sudden.
The external ext4 formatted SD card did pop back briefly right after reinstallation of CM 10.1. I was even able to browse the files with no lag or errors. Few minutes however, it disappeared again. Frustrating.
Is there an android utility I can use? I know CM 10.1 doesn't recognize exfat.

By the way, I just inserted in another ext4 formatted SD Card. This one is recognized immediately and I can access my files.
So I am thinking that the other SDcard not being recognized by the android OS may have developed a read issue. Is there a way to recover without having to reformat the card?
The non working sdcard is displaying this message when accessed by a file manager: "directory read banned".
Is there a way to unban it?
The phone can read other ext4 formatted cards.
Okay. I inserted the sdcard in my linux laptop. Apparently for some reason, it is now being mounted FAT32 formatted drive. I guess that explains the read banned message in android because of the presence of a file larger than 4GB.
Is there a way to repair this painlessly?
I would like to have a 128 GB external sd card formatted as ext4 instead of exfat, due to another device I use this card with only supports ext4. But when I put in the ext4 formatted card into the G4, it will not mount it? What's the trick?
edit: looking for non-root method if possible
Here's a brilliant tutorial from a few years back.

EDIT: Note, this is for 4.2.2 JB, but yet still may prove useful in understanding how to do it.
Thx, however it looks like that one requires root. Looking for a non-root method for now...
I havent had to deal with it lately, but you used to have to have a custom rom to support he ext4 file system, because the default android didnt support the file system.
