[Q] EXT4 MicroSD card problem - Samsung Galaxy Tab Plus

Hello guys,
I want to use my GTP to watch movies through my projector. I did some research, and found I can connect GTP to project by HDMI adapter.
The biggest problem is 4GB limitation of file size. External SD card format is fat32 which is allowed to have only maximum 4 GB.
I formatted it as ext4 and could copy bigger than 4GB. However, GTP can't recognized sd card. It said "not support file system".
Does anyone know how I can make my Tab recognize ext4 format sd card?
My tab is vanila, not rooted and has original factory ROM.

Official answer, you can't.
There is no direct support on an unrooted stock kernel to mount the external sd anything other than FAT32.
Even with a custom rooted kernel, getting the system to mount the external sd as an EXT4 partition would require some pretty fine work quite possibly using an init.d script or similar.

Have you tried the solution posted for the similar 7.7 model tab?
http://forum.xda-developers.com/showthread.php?t=1522134
There is also a way to mount NTFS format cards using the method and apps in this thread:
http://forum.xda-developers.com/showthread.php?t=1493294
Let us know how it works out. My tab is currently on loan so I can't try it myself.

I believe you need root to execute the mount command but I'm not certain.
Note that you will need to use the mount command manually each time you, e.g., reboot the device.
I suspect you may be able to get away with just adding it to /etc/fstab - that's what I would do with a Linux box but I'm not sure if that's deprecated with Android in particular.

acolwill,
Yes, I agreed that. I tried to search some script that can mount ext4 sd card, but gave up. Also, GTP does not have custom rom, doesn't it?
I appreciate your reply.
bydo,
Thanks for the solution!! It looks it is way way worth it to try!
I will try, and update the result here soon. I can't wait.
Thanks again, bro
h2g2,
Yes, but my GTP has random re-boot problem. LOL. Every 2 days, it re-boot randomly. I think rooting is not a big deal. Many awesome developer and hacker here already made good application for rooting. After that, I tried to find the command that can mount ext4 sd card, but gave up. After google, so many ways for different devices with different custom rom version. It was finding a needle in heystack.
But, I will try bydo way, and update the result for you guys.
Guys, once again, I really appreciate you answers.

I tested it!!!
Do you guys want to know the result?
It is working!!!!!
Lol, awesome!. I just tested 2 mkv 1080P and 720P movies.
Those movies worked perfect.
1080P movie was 8GB and 720P movie was 4.4GB, and sound was DTS codec.
I will make another post how to mount ntfs partition, how to play those movies. Guys, I want to post here, but I think we should share this with more people. That's why I want to make a new post, and describe in detail.
I will post the link here, so you can find it easily.
Special thanks to bydo!

I wrote a new post.
here is the link. You can get instruction on this link.

[HOW TO] format sd card with paragon partiton manager

So I decided to make this small guide, on how to partitioning your sd card with paragon partition manager… There is many different ways, including a script an xda forum member created, and ubuntu as well.. But I assume paragon partition manager might be the best for all people who don’t know how to use Linux very much..
i wrote it on my blog, if is considered spam than illtry to put the images content directly in the post
http://nitropr.us/web/2009/05/08/format-sd-card-with-paragon-partition-manager/
hope it helps some one.. i know i know there is MANY ways for this.. but well sicne paragon question keep popping up and did not see a small how to with images for new users so hope it helps least 1 person
Thanks! That will be useful for many... this should be sticky along with the sapphire/magic port (after someone starts a new thread for the newer builds. 600 pages!) Or at least a wrap stick (a thread that contains many highly used threads like in the developement and hacking section under the main thread) would be useful.
i think this is the easiest way. I did this to my card and took only a few min. def the way to go.
its a good guide, but i have a question everytime i try to format this way in paragon it says cannot create partition because all primary slots are taken, it says this when i try to resize or create new. any ideas?
Ok I resized my card using paragon my fat32 is 5gb and my EXT2 is 1.5gb. I went and tried to follow these instructions http://android-dls.com/wiki/index.php?title=Haykuro_Apps_to_SD and for some reason I am not seeing the system/xbin/busybox folder.

A few things here:
1. Unless you're planning on downloading every app ever made, you're never going to need a ext2 partition larger than 500mb, and even that is a LOT. I tried to fill my partition and managed to squeeze over 300 apps on there before I ran out of room...then I had to painfully uninstall them all cause I didnt feel like reformatting/reflashing/restoring.
2. Make sure you're using the right version of apps-to-sd. Haykuro's latest builds can be found here. The apps-to-sd versions are linked at the very top of the page.
3. The directories you're looking for are NOT on the sd card. They are only visible on the phone through adb. If you're not familiar with adb, do a quick forum search on how to set it up.

when uiu partition via usb cable the partition tend to mess up.. and not moutn o n the phone..
what you can do is, insert the sdcard check min my computer under management and assign a letter to th sdcard so the pc will read it mount it
Thanks will look into the adb issues but I am using the 5.0.2Hr apps to sd build.

[Q] Please Help, Having Problem With SD Partitioning On LG Optimus V

Hello XDA,
Before anything, I just wanted to introduce myself, and say thank you. My name is Tyler, and i've had a LG Optimus V for Virgin Mobile for a few months now. I've heard about rooting your phone, but have always been afraid to on the risk of bricking it. Thanks to this AMAZING site/forum and all the great and wonderful people that post on it, I did some research throughout the forum and found so much helpful information that I had grew enough confidence to root my phone. Now here I am, 2 days into my rooted phone! So honestly, thank you XDA, everyone has been so helpful and great.
Now, on to my question . I apologize if this is not in the correct spot in the forum, but I was unable to post in the development due to this being my first post. I'm trying to partition my SD card so I could save my internal storage space, and install to my SD. I looked at a few other posts, and gathered as much information as I can. Basically, here is what I have done so far:
1) Download/Installed Link2SD on my phone.
2) Connected SD to my PC, and using MiniTool Partition Wizard I created 2 partitions for the SD card.
As I read in a few other posts, I know there are some things to remember when partitioning. Please let me know if there is anything I missed. I created my first, main, partition. From my 4GB card, I made the first partition 3.4GB. Made sure it was "Primary", and a file system of FAT32. The remaining 306MB I created my 2nd Partition. This one, also "primary", and a EXT2 file system. Applied all settings.
3) Restored all my original files back to Partition1 of card.
4) Mounted card into phone, and started Link2SD. This is where my problems are happening. When it starts, I get a note about my second partition, and what file system I want for it. I am given the options of EXT2, EXT3, EXT4, or FAT16/FAT32. Any option I click on I get an error message. Every one says "Mount script can not be created.", but with a different note at the bottom. For the FAT16/FAT32 Option, it still says it cant be created, but theres another line under it saying "mount: Invalid argument"
All of the EXT's have the same error message when clicked on it. It says about the mount script can not be created, but then under that it says "mount: No such device" under that it says "ext2 (or 3 or 4 if that the option picked) may not be supported on your device. Try FAT32 on the second partition"
basically, every option I click I have no luck. I've seen other posts with it working on other Optimus V's. The only thing I could think of is the ROM? Im not too familiar with Rooting, etc. but I got it done. The ROM i'm using is the one given on this site from member: sublimewulf in there post with the HOW TO root optimus V. The ROM is "Stock Rom Rooted and De Odexed minus Bloat" (filename: "Stock Rooted and Optimized.zip") I guess like the filename says, its a stock ROM?
Any help, including a re-walkthrough, would be greatly appreciated.
Thanks again,
AND FOREVER XDA!!!
why dont you try partitioning the card through recovery options?

[Q] Reboot loop

I bought a new Kingston 32gb class10 microsdcard, because i decided to test Data2sd on my tf700.
I installed data2sd zip from recovery and when I booted up it said "Encryption unsuccessful", and I can only reset tablet.
I cant make a factory reset as it just reboots and displays "Encryption unsuccessful" again. I can go into recovery TWRP but all my files on my internal storage is gone, so I cant flash CROMI again.
So I copied the CROMI rom on my 32GB fat32 formatted card, but in TWRP console it says E: Unable to mount '/external_sdcard'
I should have never done this
Can anyone help please?
Apparently you didn't partition or format your card correctly - did you use gparted?
This indeed sounds like yo uare one of the many many, many that still used MiniTool, our warnings notwithstanding. Try Gparted.
Furthermore, if you can access any other storage partition in TWRP and would like to copy your backup(s) so you can reinstall you can do so with the AROMAFile Manager found here:
http://forum.xda-developers.com/showthread.php?t=1646108
Boot into recovery, flash the AFM zip file and it will start the file manager. It's a convenient option to have, but it does take a little getting used to.
I used minitool. Any gparted alternative on windows machines? I have ubuntu on my virtual machine but it cant see the internal card reader :/
TWRP couldnt recognize my Kingston 32gb, thats why it was unable to mount it. I used a old 512mb sd card and I have managed to install CROMI again. Awesome!
One thing I find confusing reading the Data2SD thread (http://forum.xda-developers.com/showthread.php?t=1962507)
I am confused as to whether I need 2 partitions or 1. I always transfer files between my tablet and computer via USB cable. So should I make one 32gb ext4 partition? Or make a small 8mb fat32 partition and the second as my ext4 partition?
Allright got my questions answered else where.
I am using the Gparted CD to boot up from and format my SD card.
To anyone else do not use MiniTool as it doesnt work!
Thanks guys.

Yeah saw your post on Data2sd thread. The post Muffin has made should be edited, as ppl tend to read the first 3 posts from the op and not the replies... Oh well no harm other than many posts from users. For a second I thought I turned my tablet to a brick..

Yeah, the latter effect is what I'm trying to stop: I was in the same situation, with the added bonus of nobody having figured out how to recover. It took me an entire evening and a lot of stress to get back my microSD card after it stopped working altogether. Once a thread gets more than, say, 300 posts you can't really blame a new reader for not going through all of them -- the OP should be updated, however, when an issue is as clearly established as this one is.

SD cards: exFAT Fat32 file sizes

Just wanted to check peoples thoughts on this. Had a 32GB Sandisk card corrupt (i think) on me the other day. Woke the phone and seen the SD card icon in the task bar as if it had just mounted the SD but it had unmounted it and said that there wasn't one inserted. Have yet to try it in a PC to see what (if any) files I can recover.
The previous night I had made a nandroid backup (Philz touch), there was something not quite right with the file sizes not showing on screen but it seemed to work the second time around. Can't recall if the card was formatted as FAT32 or exFAT, but if FAT32 could one of the nandroid files caused issues if it was over 4GB? Anyway going to see what I can possibly recover and if it can be reformatted again before possibly purchasing a 16GB Samsung card here: (http://www.7dayshop.com/samsung-plus-microsdhc-uhs-1-16gb-memory-card-class-10). Dont mind the smaller size if its more reliable.

I quite highly doubt a Samsung SD card will be more reliable. Don't know what's the fuss about SanDisk corrupted but I myself or anyone in my friend/colleague circle have yet to face a problem with SanDisk!
And the first thing you should do is format your card to exFAT, I really don't know how and why people uses FAT32

This is the first problem I've had with it to be honest, had it or over a year and was using it in my HTC Sensation previously. I'm trying to remember if it was exFAT or FAT32, I remember a ROM (Google Edition S4 ROM) not being compatible with exFAT and checking mine out of curiosity, but just can't recall what it was and never flashed the ROM. I didn't reformat it coming from my Sensation so it hadn't changed in anyway.
Luckily all my photos were backed up to dropbox so nothing lost of too much importance. Need to get a microSD card reader to see if its completely borked or if files can be retrieved.
Someone will correct me if I'm wrong but I'm pretty sure that Nandriod breaks the files down smaller than 4GB if you're running on Fat32 so I doubt that'll be your problem. Mostly because the FAT32 architecture just won't accept a file that big unless the Linux kernel of Android ignores the limitations. I would HIGHLY recommend NOT restoring a nandroid backup if you think the sizes are off or if you're attempting to recover the data without and MD5 checksum. That's all sorts of bad juju.
As for Sandisk vs Samsung, I have both, I've never had a problem with either. My sammy card is in my TF201 and my Sandisk is in my I337 as it's a faster card from my benchmarks. But like I said, no problems with either.
As for data recovery, go check out Recuva, it's supposed to be pretty good especially for being free. Since I'm IT I have professional grade software for data recovery and don't have tons experience with Recuva. A couple tips about data recovery. Once you determine you want to recover data, DO NOT WRITE TO OR FORMAT THE CARD, that'll prove to make the entire process more difficult. it's going to take a good long time, at least an hour for the initial scan. Do all the work on the card from a computer and not through a connection to your phone. Anyway if you have any questions or possibly want some help shoot me a PM, I'm happy to impart my knowledge.

I thought it should break them down, it was just the /data partition that includes the apps and app cache, if it could be over 4GB stored as a .tar file would that still be broken down as such? Won't be attempting to restore the nandroid (if its even still recoverable) as I have flashed a pre-rooted stock odin firmware and its actually really smooth (maybe thats due to the sd card not being inserted). Although I seem to be having an issue flashing a custom ROM, as even after flashing the firmware via odin then trying to flash a ROM via Philz touch its still bootlooping (even with a wipe/factory reset and clean install format). Haven't attempted a different custom ROM but just havent had the time to test that out. Thinking I would have to download the original firmware files and start from scratch with rooting and adding a recovery to see if that solves it, but think I'm going to sit tight for the moment.
Thanks for the recommendation and the support, much appreciated.

Well in general in windows when a FAT32 structure is asked to write a file larger than 4GB it'll flat out deny it (usually saying something like disk is full). If you're writing to a FAT32 structure using something that increments the file as it writes it, when it hits the 4GB file size limit, it'll usually say again disk is full and the file will go corrupt (which can lead to the file being undetectable). I do believe that Nandriod is smart enough to realize when it gets to that 4GB limit it'll break the tar into multiple files or else the linux OS would probably kick back an error. As for your ROM bootloops and things like that, I'd see about another ROM, maaaaybe it could just be that the ROM you flashed doesn't like your phone (I have an i717 that does that with a ROM). If that still doesn't solve it, like you said. Start at the beginning completely clean and just work through the entire process.

Cheers, I had re-downloaded the previous version of the ROM which I was on before hand and made sure to check the md5s but it still wouldn't boot which was annoying, but a full install from scratch may be the way to go. Never had bootloops before and was just worried after I had wiped and started a fresh and it still happened. I think the real lesson is to make sure to backup ANYTHING that is of value to you!
Luckily I had just happened to use the auto backup for photos to dropbox so got off lightly this time!
I have had the EXACT same issue 2 weeks ago.
I bought 2 x 32gig microSD cards (Sandisk)
1 for my phone and 1 for my digital camera.
Recently the 32gig one in my phone just DIED for no reason at all. Lost all my files, music, everything.
I contacted Sandisk, had it repalced. In the meanwhile i purchased a 64gig Samsung one.
I am yet to have an issue with the Samsung 64gig, but only time will tell.
On a plus note, Sandisk sent me a replacement 32gig card very quickly (infact too quick, i purchased the 64gig Samsung one on the idea that the Sandisk replacement was going to take months... in fact it only took 6 days...)
Cheers
How did you contact Sandisk, did you need to give a serial number or provide proof of purchase?

I always use Fat32 on SD-cards. Why? It works on every Rom, with every kernel, every recovery, on every device, every camera, every computer, all the time.
When not in need of files greater than 4GB Fat32 simply is the way to go, compatibilty-wise.

OTG and ext2 support

I never expect an issue with a USB device formatted as ext2, but I'm unable to mount o=under Oxygen, I can in TWRP however ext2 should be a support FS. The only option Oxgyen 9.5.4 offer is format, which is wrong.
On a related note, I really can not understand why data transfer to and from android phones is so bad, 'File transfer' is find for small transfers want to move 20GB, not a chance, it always hangs faild ... It is either 'File Manage'r from TWRP (which works well if you plan ahead, as you need to create the folders first that you want moved), or ADB push/pull which works well, but is not what I'd call use friendly. I miss SDCards as that made it so very much easier.
Anyways anyone know why EXT2 OTG is not supported?
