I was wondering if anyone could point me to a way to be able to use an ext4 formatted sd-card with a stock lollipop ROM?
I'm usually using CM which had this built in, but might have to revert to stock due to an annoying lag with a Bluetooth keyboard on cm.
Marshmallow uses encrypted EXT4 for Adopted Storage. With LP it shouldn't work at all. At least stock Note handles exFAT, which the custom roms don't. More annoyingly, the Note doesn't support USB to Go media with NTFS.
Thanks! That's a shame, so no way to get ext4 support even with one of the custom kernels? I tried searching, but didn't come up with anything conclusive (and the xluco kernel I tried didn't seem to help). I did try an app called ntfs mounter, which claims to Mount a range of formats, but it didn't seem to work either.
And it seems not even exfat would be a reasonable alternative? I'd like to avoid it anyway, as Linux support isn't great (and it feels wrong not to use ext4 if you're using Linux anyway). What I would need if I were to try the stock ROM is some way to have files larger than 4gb for my Linux chroot image...

I have tried to find information on this, and I'm struggling.
What file system does the evo use by default? I know it's EXT2 and fat32 for camera card, but the main partitions I do not know. Yaffs?
I've heard things about Yaffs2+EXT2 (refered to as godmode), using EXT2, using Yaffs, and using EXT4, with or without journaling. I want to make my file system faster. I keep finding very diluted information that never gives the whole picture. How does yaffs2+EXT2 work? How do the different options perform relative to eachother?
I'm guessing nobody is going to answer... got pushed a couple pages back on the forum
I'll tell you what I know, which is limited. the ext2/3/4 are used for storing apps/cache on the sdcard. It is separate from the fat32 partition which is where everything else on the sdcard is stored, ie pics/roms/backups... Having an ext partition setup will not automatically speed up your phone. You must use a sdcard that is class 6 or higher to give you the speed you desire. The ext2 partition is used with godmode i believe. I had better results from the non-godmode synergy, so I didn't bother learning everything that I should have. Ext3 is what is primarily used for DTA2SD, which I have been using for 2 or 3 years now. I have yet to see a rom that uses ext4. The only thing I have seen about it, is the recommendation to stay away.
Not sure about YAFFS, you could always google it though.
Thanks, this was helpful.
Appreciate the comments.
I am running ext4 from a a script on my gtab. Can i run ext4 with this script on the evo?
I read somewhere that the evo cannot use ext 4. Check out synergy god mode, it has some weird hybrid file system if I remember correctly.
EVO default is YAFFS2. Godmode is YAFFS2 + EXT2. EXT2 and file sytem and YAFFS2 as wear leveler layer.
Read a little on Linux history, I know that EXT2,3, and 4 are newer than any YAFFS, with EXT4 being the new standard for now. Basically all of the new phones use EXT4 now, that was made the new standard or something of the sort with Gingerbread.

Has anyone had any experience with using their SDcard with either the ntfs file format, or any other? If so, how well did it work and what did you think of it?
I know there are plenty of threads out there asking whether it's theoretically possible to format the SDcard to any other file systems (usually asking ntfs) and still expect android to read it, but I haven't found actual usage statistics (stability, speed). I'm interested in reformatting my SDcard to either NTFS or 4ext (I use linux, so pretty much any file system is game), however I don't know if this will be better for prevent files from easily corrupting, or if it'll still be the same (theoretically it should).

I didn't know that 4ext was a file system, I believe you meant etx4 :trollolol: 4Ext is a recovery for some android (HTC) devices.
I recommend using 4Ext to format your sd card with whatever it recommends. I think it formats to part ext3 and the rest as ext4, but I can't remember.
I think you can use NTFS or any other popular formats with android though
Yes but not on the DHD. Kernel support is required for R/W in those formats. For example, the Samsung Galaxy S3 can use NTFS and exfat formatted SD cards. The DHD can only access fat32 formatted cards and use a multi-partitioned (ext3/ext4) card for app2sd.

jeezus, I meant ext4 I us 4ext rc8 on my i4g, so I'll probably give it a go sometime.
Is there a kernel that supports a 64 gig sdcard?
Or is there a mod to fix it?
Or do I have to format the sdcard for AOSP?
Please someone answer me

KT747 supports exFAT if that's what you really want. But if you're using AOSP, you can format the card as ext4 instead and use it with no problems with any kernel. I know CM10.1 supports mounting ext4 SD cards at boot (I use it), and if you're using an AOSP ROM that doesn't support mounting ext4 at boot, check out goo.im, and navigate to invisiblek's folder, and he has a zip you can flash to mount ext4 cards at boot.

Is there a filesystem supported by both touchwiz kernels and AOSP kernels?

Aside from FAT32, no. Since exFAT is proprietary, AOSP can't include it (for the most part; obviously, KT747 had it), and since 90% of users will only use Windows PCs, Samsung has no reason to support Linux filesystems.
In reality, both TW and AOSP kernels work with ext4. The root filesystem on our phones uses ext4, so the kernels have to support it. But since very few of their customers even know what a filesystem is, let alone which one they're using, Samsung sees no need to support mounting ext4 SD cards at boot. The kernel does support ext4, but Samsung went and butchered the vold.fstab so ext4 cards wouldn't mount correctly.
So, for no real reason whatsoever, FAT32 is the only filesystem guaranteed to mount in both AOSP and Touchwiz at boot without hacks (if you look around, there's a guy that's working on getting ext4 cards to mount at boot in TW). It sucks, especially with a 64 GB card.

So that is wat I thought just making sure there wasn't any ones I didn't know for linux. since I do not have a SD card reader for my PC I tried the alternative route of formatting the card through my fone that Is provided in KT747 but wen I try to put in ums mode with the app it appears on my computer as a CD drive and I can not access my card? Any thougts ?

I had that problem. My solution was to toggle USB Debugging. When it was off, turning it on fixed the problem. When it was on, turning it off would fix it. I thought they would have fixed that by now; guess not.

Sure, if it works. I was having that problem when CM had built-in UMS, so I don't know if the problem will be the same with the app.

Has anyone managed to get a NON-FAT partition mounted from their SDXC card?
I tried so many mods, tricks, and patches to get Link2SD running on anything other than FAT that I finally bricked myZ550ML. Since I can't manage to un-brick it after many hours of trying (separate thread), looks like like it's going back.
I'm trying to decide whether to get another one. Right now, I'm concerned that this phone may never support ext4 or F2FS (at least until Android M).
Thanks! Carl
Wondering if anyone has managed to figure out a way to get this working, or if I'm just missing something. I've tried everything I can find online, including a custom kernel (EX), (both) paragon NTFS mounting utilities, stickmount, a couple different TWRP-flashable .zip's, as well as miscellaneous other root apps that supposedly will mount NTFS, all to no avail.
Running 9.0, stock rooted + EX kernel and Magisk. And unfortunately FAT32 or other formatting isn't an option in my case. Any thoughts or advice or is this just a no go? Thanks!
Android doesn't support NTFS and is unlikely to ever support it. If none of the apps you've tried work then there isn't anything you can do except format the drive you want to use as FAT32. I know that isn't an option, but you don't havr many options here.
Paragon "works", but only in a couple of specialized file managers. There's no generic solution I've seen that simply mounts OTG as a directory. There is a Magisk package that claims to do this with vold, but it's only supported by an older Magisk version and doesn't support Android 9 yet.

Android only supports FAT32/Ext3/Ext4/exFAT. Why is FAT32 not an option? It will support up to 2TB partitions and although it doesn't natively support encryption, it is possible to encrypt data on a FAT32 formatted partition. What is it you are trying to accomplish?
The OP likely has a device formatted as NTFS and doesn't want to go through the trouble of pulling off the data, formatting, and replacing the data. Unfortunately for him, he's going to have little choice but to fornat to be able to use it.
exFAT USB drive wasn't supported on my P2XL Pie, tested a few days ago. Had to format FAT32 through Android (since the only options were FAT32 and NTFS in Windows File Explorer).
i may be a little late to this thread, but
total commander from c. ghisler and
usb stick plugin (tc) from ferenc hechler
does that. it worked on Android 8 at least, on android 9 i have some troubles atm, i can only copy data to my expandable sd card storage, but maybe it's a bug on my hand, worth a shot.
there is a free version of the usb stick plugin as well and total commander was always free without ads
