if you format your external sdcard ext4 will kies still be able to read/write?
anyone tested?

Hi all,
I am testing a freshly formatted and aligned ext4 partition on my SD for APPS2SD+, and so far, restoring with TB it seems to be flying! And the APKs are indeed being written to the sd-ext mount.
So when I switch ROMs I'd like to format with CWR, but I wonder if CWR will format with ext4, or ext3... is there a way to format the sd-ext with ext4 without a computer?
Thanks!
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.
After formatting the card on linux via gparted, android shows the sd card as damaged and asks me to format it? How does one mount an ext4 card?
I am just guessing, but since the SD has to be compatible as USB Mass Storage Device, it must be formatted in FAT32. Windows for example cannot handle linux/UNIX specific partitions like ext3 or ext4.
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

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.
