I've been trying to format my 32GB sdcard to a filesystem that can read files over 4GB. Main reason being I use HDMI connection to view 1080p movies on TV.
Anyway, I've tried EXT2, 3, 4, NTFS, exFAT, and all of them come up with the "broken sdcard" message from android when I try to mount the sdcard.
I'm using kernel version 2.6.32.59-MB860-MROM and using the lastest MROM based off CM7. Anyone have any insight on where I can go from here? Thanks.
The whole entire Android system assumes the user storage (internal or external) is formatted as FAT32. This is much harder to change than you think. A simple reformat won't do.
You need to have at least part of your SD card to be FAT32 because many applications are using it to store configuration and data. You can have two partitions on your SD card, but I am not sure if video player will be able to use any partitions other than FAT32.
I found a way to format my external 32GB sdcard to NTFS and still have it mounted on the phone. Pretty easy actually. I'll post it here for those that might be interested:
-Used Paragon Partition Manager 12 on my Windows machine to format my external SD to NTFS
-Atrix wasn't reading the card so I tried a program called Paragon exFAT, NTFS, & HFS+ by Paragon Software. Link: https://play.google.com/store/apps/...251bGwsMSwxLDMsImNvbS5wYXJhZ29uLm1vdW50ZXIiXQ..
-Paragon was not able to mount my sdcard automatically as it just gave me an error, so what I did with the rom im using was mount manually to /mnt/sdcard-ext. Should be good to go after this.
Been using it for a few days and everything is working well so far. Only annoying thing is everytime I connect by usb to my comp and enable usb storage I have to manually remount once I disconnect.

At some point in time, probably when the nand was released for HD2 (I had one), we had to use a tool to format our SD card, I think to ext4. Eversince that my SD card was accessible to the HD2 & then the Evo 3D afterwards. Today after I got my Galaxy S III, it is unable to access part of the SD card, although in settings it shows the actual capacity utilized on the SD card.
Is there a way to fix that, considering the SD card stopped being read by the PC after the reformatting to ext4 sometime back ?
Does your SDcard have one or multiple partitions?
What do you mean by 'parts of'. Are there files/folders you cannot access, is something missing, ... ?
The S3 should have no issues in mounting and using EXT4 filesystems since it's internal storage is using the same FS.
Btw there are tools to at least read EXT4 filesystems under Windows (but none I know of to actually use read-write mode, sadly)
duh
I guess he might want to keep the contents =)

I installed ES File Explorer & it only shows the folders that were created by ICS. All my other content is not shown at all. If there is a way I can access the SD on the PC, move all its content then format the SD to FAT32 & move them back. This will solve the problem.
now I have got it. I am an A...hole
I did not notice the phone has internal SD like my pad, as my Evo 3D did not have. So what I was seeing was its internal SD. When I enabled root view in ES explorer, I was able to see 'ext SDCard'. The other thing is, my SD Card got read on my PC. Maybe cause it is Win 7 now. Earlier, Win XP did not read it.
How to mount an USB stick formatted ext2/3/4?
When I connect a FAT formatted stick, it works, NTFS too using the Paragon_NTFS TC plugin.
I thought ext2/3/4 is supported, when the system and internal storage is on an ext4 partition.
Has the tablet to be rooted?
Tried also an ext3 formatted SDCard in the tablet, the result is the same - it says the card is empty or an unsupported filesystem..
The format it is told to read the sd card is different from the format it's told to read the system as. I'd say you'd have to be rooted if making any changes to what's readable versus what's not. The only thing is I'm not too sure on how exactly you'd do that other than using a cwm recovery and adding an extension partition on your card.
I'm afraid I need to do something like this: http://forum.xda-developers.com/dell-venue/general/guide-ext4-microsd-card-dell-venue-8-t3042906
The main problem is, I can't root my Venue because I've encrypted the filesystem.
I'm afraid I have to reformat my USB sticks to FAT32/NTFS ...
Decrypt then? Root and recrypt?
Edit: did you buy a large as card?
My 32 is in but have only had issues with higher cards like 64 and 128. There's an application I once used to format the card on board but when I plugged it into PC whether Linux or win, they'd get corrupted. So now the 128 lives in my laptop and the 64 in phone. 32 for the tablet for me is plenty. Onboard formatted to exFat I believe. Backup your goods. [emoji12]
Edit 2: I'm sure there's an app for that. No? Sorry, I was talking micro SD like a MF, lol! Stuff like that is not cool but I throw everything on my biggest USB 128 and it's formatted to NTFS but my others are just fat and don't read either.
According the instructions when encrypting, there is no decrypting, only factory reset.
I have a 64GB card, formatted to FAT32, no issues so far.
The idea was to use an EXT3 formatted USB thumb drive for big files (movies), so far I'm bypassing the problem with a NTFS formatted USB thumb drive and the Paragon_NTFS TC plugin but I have to copy the big file to the internal storage because the plugin doesn't make the NTFS drive visible for other apps than TC (Total Commander).
Edit: There are apps for mounting USB EXT2/3/4 (USB OTG Helper, USB Mount All, StickMount) but they all require root.
Then follow the crowd and. ..
Root it, root it, root it.... lol
Those were the apps I've used before and I root every device I own before I even get comfy with it.
I recently tried decompressing a file that was just under 4gb to the internal sdcard. the decompression stopped at 52% (about 2gb) Think it's a fat32 file sytem with 2gb file limit. . booting to recovery and using ubuntu I can only connect via mtp from the mounts menu. Gparted cannot see the device. I'm thinking gparted does not view mtp as a local block device. any ideas how to format the 24gb internal sdcard to ext4 or reasons why I shouldn't ? thanks.

MTP is a real PITA, imho. I'm pretty sure that GParted would not recognize an MTP or PTP connected device as local block storage; the device handles its own disk management with these protocols.
How were you decompressing the file to the device? It might be better to decompress on your Ubuntu box, then transfer the file through MTP, ADB push, or cloud storage service.
Do you have enough storage available on the destination device to accommodate the decompressed file size? Try this in a terminal on the device:, look at the line for either /sdcard in TWRP or /data in the ROM, respectively.
Code:
df
Have you tried going into either an ADB shell or terminal session on the device to check the file system type?
If you are in TWRP, what is the output of the following in the device terminal?:
Code:
mount | grep /sdcard
Can you still get into a ROM? If you are there, what is the output of the following in an terminal or ADB shell?:
Code:
mount | grep /data
Thanks for responding. I can't say I diddn't think of decompressing on the pc and then transfering but I just felt like moving down the path of converting to ext2 for it's resiliency . as far as space available I had at least 12gb. Im also running multi-rom and I also kinda wanted to see how that was going to work out. The multirom directory contents are not visible from the internal rom they can only be seen from recovery and copied there.

Interesting... EXT2? The only application I have seen that for recently is a dual boot scenario where Win7 and Linux share a common data partition and you want to use something better than FAT or NTFS. EXT4 is journalled and is more the standard of late, for most partitions under Linux.
Not sure Android even supports EXT2 and even if it does, how would you go about formatting an internal sdcard partition to it. I have used Gparted to redo external cards in a card reader, but how would you do the internal partition, especially since it seems to be mounted at /data/media and /data is ext4?

Right.... I am familiar with that...
Internal /sdcard/ is not a physical MicroSD card, nor is it mountable as USB storage media, to my knowledge, just as an MTP/PTP or ADB device through the ROM or TWRP, respectively. That is why I am asking why and how you might go about formatting it to ext2. Not that it's impossible, just don't see why you'd want to do that...
reason for formatting to ext4... (I mistakenly wrote ext2 instead of ext4 on my previous post)
1. to possibly solve file size limitations of 2gb for fat32,
2. ext4 (yes ext4 not ext2) is a journald file system
3. it would give my phone wings as if I poured redbull on it. (not really... I just needed a 3rd reason)
My phone is 32gb. I believe it is 8gb emmc and 24gb sdcard_internal. (I also have an Sdcard_external which is the removable micro sdcard but I'm not asking about that) Doing this ext4 formatting May be more of a hassle with permissions issues when running multiple roms anyways. if it can't be done then no biggie. I was wondering if twrp or philz had the capability

ext4 makes far more sense. Not that there isn't a part of me that now wants to figure out how to make it ext2, just for the exercise....
You still didn't answer my original troubleshooting questions though... What happens when you try the df and mount commands I referenced? This may be a moot point after that.
Here u go
Alright, this is telling me that the /data partition, where the internal SD card is mounted, is already ext4. It has 6 GB free.
I am unable to see the filesystem on the external SD card with this output, but it has just 3.5 GB free.
So again, I think you would need to decompress the file on the Ubuntu box, determine its uncompressed file size, then transfer. Depending on the compression ratio, you may be over the 6 GB. Either way, you are cutting very close and not allowing much room for new software or local files.
Can you guys speak in English please
Can I or can I not claim all of the 30 GB of storage
Thnx
I am trying to mount an external sd card that is ext4 file system. I am mounting it on a directory of my internal sd card. It seems only root sees this. If I transfer a file to this directory as normal user it gets stored on internal sd. If I run df as normal user I don't see the ext4 mount, but if I su then df, I can see the mount. Basically what I'm trying to accomplish is using my external sd with ext4 instead of exfat.
Also if I insert my 128gb sd into my Linux computer it only shows I think 25gb? If I put it in phone I see 128gb? Do I need a new card reader for my computer?
I download a lot of stuff onto phone and sync with computer, using mtp sometimes crashes, that's why I'd like to use ext4 and just toss my sd into computer and transfer.
I don't know why Android wants to use exfat when ext4 is so much better and native already. Maybe just to keep support for windows?

What I've tried:
I partitioned the sd card using minitool partition wizard. I partitioned it into 100gb fat32/exfat and 20gb ext4 partition. I was able to install apps onto the ext4 partition and read things from the fat partition. However, there was a couple problems. I could never see the ext4 partition, all I saw was the internal storage (32gb) and the sd card fat partition (100gb) so I didn't know anything about the sd card ext4 partition.
Secondly, on reboot the fat partition would not mount. I would have to take out the sd card out and put it back in to get it to work.
Thirdly, even when the fat partition would mount it would not show up in windows mtp. When I plugged the phone into the computer all that I could see was the internal storage, so if I wanted to put anything onto the sd card I would have to take it out and put it into the computer.
I've used this adoptable storage module to enable installing apps on sd card. It "worked" but I face two problems with this: solid explorer only reads the sd card so it says I'm only getting 120gb (not 120gb + 32gb) and secondly it doesn't load magisk modules properly, so vanced youtube or viper4android don't work. Also now I can't get reverse this.
I've been trying for a while now, I would really love some help.
Bump!
I've even tried contacting Samsung and they've done nothing. I have kernal auditor and it looks like I can make a init.d file, is there something I can do with that?
I would completely format the sd card (With android settings) and then have you tried simply going to settings/apps/*the app* (maybe have to click storage or something) and then move to sd...
Check out the second from bottom in the pic if it doesnt work and try again

I think that the setting in developer options worked! Easier than partitioning.
