I have 64GB sdcard and my phone is rooted. I lost all my data on card because of exfat file system. I have found out it is very unreliable. Reliability is worse than FAT32 system.
I would like to have NTFS or ext4 file system on it instead of exfat. I tried several apps: ezymount, NTFS mounter, Paragon NTFS & HFS+. No app was able to mount the card. Is there some way to use NTFS sdcard in galaxy s4?
Never had any problem with exFat filesystem with any samsung device I've owned. You'd better check the reliability of the card you're using!

No easy way. The kernel and modules set it up for exFAT. There is no way to change it without a significant change to the kernel and some support in the OS, initramfs etc.

hi i have the 16gb sdcard which is fat32 and i want to change it to NTFS because i need to put files on it larger then 4gb and when i tried NTFS android said it needs to reformat is there anything i can do?
Not sure if Android supports NTFS. But the driver (ntfs-3g) might be able to be included in the kernel.
NTFS will reduce the lifespan of your SD card too.
edit: If you have an EXT partition, stick the files on there then access them with a file manager?
Do the SGT 10.1's already have ext4 or not? if not, is there a way to get it put on there?
personal reasons.
yep /system /data /cache are all mounted on a EXT4 filesystem on my stock Tab 10.1

But internal storage is FAT not ext4... This is why over 4 GB files does NOT supported...
ext4 or ext3 file system has better performance than FAT32 ... Archos's Android devices use ext3 or ext4 for better performance and there isn't any restriction about over 4 GB files (especially for 720p movies ... ) ...
ext3 or ext4 file system can be seen on Windows platform without any problem by means of one application...
My old Archos 5 Internet Tablet has 32 GB internal memory which ext3 file system. I can transfer over 4 GB movies without problem under MTP mode ...
No, there is no fat32 partition on the tabet. It's all ext4, more infos here:

The problem with files bigger than 4gb being transfered via mtp lies somewhere else.

As I said before Archos's MTP mode supports without problem.
Moreover, Archos's files system can be formated FAT32 or ext3 ... Both system are supported!...
I think Samsung Galaxy Tab's files system of internal memory is FAT not ext3 or ext4 ...
If so can you instert ext3 or ext4 formated external usb pen drive via "usb adaptor" .... Well I don't think so...
You might think it is fat32 but it is ext4. Download a terminal emulator, type in "mount" and see for yourself. It has all been explained in the links above.
And sorry, I have no idea what an usb mount has to do with the fact that the internal storage or "/sdcard" is part of the /data partition and /data is ext4.

I wanted to ask gently, if someone is in a position to build a kernel that allows the SD card to be formatted in ext(2,3,4)?
I've pushed a 32GiB card into the tablet, and it would be very nice to move more than 4GiB sized data on the sd card.
Other file systems would of course possible
I have the P6810.
I don't think you need a custom kernel. The internal flash memory is already formatted with ext4 and supports files larger than 4GB. The problem is with the Samsung automatic sd-card mounting which forces fat32 only.
Is it possible to manually unmount/remount the external sd card with ext4 file support via shell or custom app/script?
The kernel's got ext4 support.
To mount the SD card, run the following in a terminal (as root):
mkdir /mnt/sdcard/ext
mount -t ext4 /dev/block/mmcblk1p1 /mnt/sdcard/ext
Your SD card will then be mounted in the ext directory on your Internal drive.
Resolved: by switching to the custom ROM Buttered AOKP 4.2.2 [+Aroma] and using its the default kernel. The OTG connected SDCards formatted as either ext4 or FAT32 was automatically mounted with RW accessable. Stickmount was not required. It seems odd that the neither the popular SentinelROM/KTManta nor Tasker650/Trinity Ten custom ROM/kernels would mount the same ext4 formatted SD cards.
I am running custom ROM/Kernel combination Tasker650 TX34 and Trinity Ten. Using gparted I can format an external SD card with FAT32 or NTFS and the SD card is automatically mounted by the N10. Settings->Storage can mount and unmount the OTG connected storage without issue.
If I reformat the SD card as ext4 it is not auto mounted but Settings->Storage does show a "Mount USB" button. Unfortunately clicking on it causes the SD card reader's light to flash but the file structure never show up in "/usbdisk". Note: I have the same problem with "SentinelROM and KTManta".
What is strange is that TWRP can see and mount the ext4 formatted SD card without issue from a "/usb-otg" mount point. File browsing the SD card also works but only in TWRP.
I tried from a terminal session to mount it manually:
> busybox mount -t ext4 -o nosuid,nodev /dev/block/mmcblk1p1 /storage/usbdisk
but it always return the error that "/dev/block/mmcblk1p1" does not exist which is true.
From everything I've read ext2,3,4 formatted SD cards should all be recognized. I am looking to load files greater than 4GB and have full RW access to the SD card. NTFS can accommodate the file size but is limited to Read-Only access.
Maybe the mount point is different for ext4 formatted SD cards but I can't find that mount point. If anyone can shed some light on this issue I would appreciate it.
Thanks

Hi, is it possible for our TN 7 to have exFAT support?
My SD CARD don't work with FAT32, NTFS or EXT4 fs, I tried to fromat it from Linux and Windows as well, always some problems.

You may need to do a full format of the partition table.
Format sdcard in MSDOS then make fat32 partition. For any modern memory or storage, use GPT format and then make partitions to suit. Partitions are best in fat32 or ext4.
GParted is a partition manger GUI for Linux that should do the job.
Any update on this?
Does the TN7 support exFat formatted sd-cards or only Fat32. Would be quite a bummer ... due to the 4gb file-size limitation exFAT or NTFS (not happening for sure) would be highly prefered.
Edit (i think i found the official answer)
w_w_w.evga.com/support/faq/afmviewfaq.aspx?faqid=59464
Well ... bummer!
Is there a possibility to add exFAT support through other means? A modded ROM maybe? Or a "patch"? (i read that there is something for the Galaxy S3 with CM10.1 and that CM11 supports exFAT from the start.)

I tried for a while with different apps to get another file system to work, but never could get it figured out. No matter what I did, fat32 is the only thing I could get to work.

Use "Bootice" by "www.ipauly.com" to format the sd card to FAT,FAT32,NTFS. Or you can try some another windows utility to format (I think your windows right click format fn is not working properly.) There are various options to choose, choose "partition editor -> your sd card -> create partition table as USB-HDD" option. This will recreate the partition table of the sd card.
I have tested exFAT with TN7, but it doesn't work. FAT,FAT32,NTFS work. I think EXT2/3/4 will not work with sd cards.
If those devices would at least support ext4 on their sd-cards ... just for files >4gb.
Thanks, will try bootice.
TEGRA NOTE 7 compatible micro SD card file system
I bought a 64GB micro SD that the TEGRA NOTE wouldn't read. As it turned out the problem was caused by the exFat file system on the card that the T.N. wouldn't even recognize. NTFS is recognized but it is read only and finally FAT32 is fully recognized, I am now able to read and write on my SD card. I used bootice by Pauly to perform the operations as suggested above, chose "USB-HDD" option and all is OK now.
