How to mount ext4 formated sd in Overcome ROM

This article is a google translate from my article in Greek from here: http://fwlia.k0uk0s.gr/2011/07/mount-ext4-formated-sd-android.html
Sorry for any language mistakes
Well, quick and dirty way to mount ext4 file system on the external sd.
1) We need external sd and kernel with ext4 support (Overcome has)
2) Format from a Linux machine the sd to ext4. The best way is to format the sd from a card reader. If you want fat32 partition, put it first and then the ext4
3) Put the card into the device and do boot. The android will grumble that there is a problem with sd, ignore it. If you have the first partition fat32, it will not say anything
4) In the internal sd (the fat32 which has the device from factory) you make a folder called external_sd. Most of you must have the directory
5) You install on android the http://market.android.com/details?id=os.tools.scriptmanager
6) you make a folder in the internal sd named scripts and there you make a text file named mount.ext4 and this content:
#! / System / bin / sh
mount-t ext4 / dev/block/mmcblk1p1 / sdcard / external_sd
7) If you put the first fat32 partition, then change mmcblk1p1 mmcblk1p2
8) Finally, in the Script Manager we installed before, pick the mount.ext4 and tick run as root and run at boot
Reboot and complete.
I have yet to find a way to become the ext4 unmount when the device connect to usb.
Now you can put that hd movies in sd whithout the 4gb per file fat32 limitation. You just need a linux machine to copy them in sd.
Have a nice day

Thanks Alot!
Dude, you are my hero! Hate FAT32 like the plague. Now I can rid myself of it once and for all!

yeah! it's done, good job. but i have some bug to report can not use Mass storage to connect to PC , can be connect by Samsung Kies only.

A normal Win PC doesn't know about ext4... As the OP states you'll need a Linux-machine to work with.

Can you store a 6 GB movie on internal storage ?

I know that external storage of SD card is limited to Fat 32 and the max size is around 4 GB. What about internal storage? Can I transfer a 6 - 8 GB movie file onto the internal storage of the 7.7 ?
I have the Playbook and I can certainly put a 6-8 GB movie in it.

I saw a guy put 10GB mkv into /SDCARD

easy
$su
# dd if=/dev/zero of=/sdcard/blob
wait a few seconds and
ctrl+c

to overcome the fat32 limitation you can format the sdcard to EXT4 and then copy anysize you want to it
all our phones by default can read linux partitions and fat partitions
if you are running Linux as your desktop PC you would not have any problem copying & pasting files to and from the phone
if you are a windows guy, just install the add-on for windows to read Ext2 partitions

I have windows 7 (64-bit) on my PC. What add-on are you refering to? Is it an application that I have to install on Windows 7 ?

Hi just google Ext2 and you will be able to learn all about it.

thats a shell commands to create a file for the time you wait... it should create a very large file very quickly, so you will see if it handles big files or not

Eeeexcelent!! I shall have to get an EXT2/3/4 driver for my Win7 box and re-format my 64GB SD!

or just install linux in a virtual box inside windows
then use the VM USB pass through so when you plug it into the PC it will automatically mount on the virtual Linux box
if you want to do it your way, you'll need this http://ext2read.blogspot.com/2010/04/ext2read-22-released-now-with-lvm2-and.html

So, using Ext2 volume manager, when I select a volume and want to change the partition type, A) will that essentially re-format the disk, and B) which one is ext4? I don't see that...

Please help.
After I run the above program, I don't know what to do next.
All I want to do is able to transfer my 6 GB .mkv movie file to my SD card so that I can either view it on my Galaxy Note or the Galaxy Tab 7.7.
How do I go about doing this? Is there a simple tutorial guide to using the above application? Do I use it to format my micro SD card? Will it work for a 64 GB card?

The internal galaxy tab 7.7 can take any kinf of file, it dont have de 4gb limitation, but the external sdcard is not readable if formatted in ext4, i have try it and the tab say that the sd is corrupted. I repeat GALAXY TAB 7.7 WITH HONEYCOMB CAN`T READ EXT4 FORMATTED MICRO SD

You need use "drive mount" to mount a ext4-formatted sd card.
You can get it from android market.It's free apk.
Here are some of my experience:
1:I use gparted live cd to format my sd card.
2:ext2fsd as windows ext driver.
3:"Drive mount" to mount ext4-formatted sd card on tab 7.7.

What is the difference between EXT2 and EXT4 ? Which one should I formated into in order to be able to put 6 GB video file on the microSD card?

[HELP]Can't read SD Card after formating

Guys help me please. I partition my sd card. few months ago. last night i formatted my SD card. after that. SD card can't mount. please help me. what to do ? also my computer can't read it please help me how to fix it . thanks in advanced.

first backup any data you have on your sd card
remove all partitions with minitool and create a new partition of fat32 and format it with minitool
next boot up your phone with the sd card in
goto
settings
storage
unmount sd card
erase/format sd card
now go into cwm - you sd card will now be mountable
for the 2nd partition create it in cwm
cant remember exactly where the option is from memory but its under something like partitions
just create a 2nd partition of 1024mb with 0 swap
you can then copy any backups back to sd card

if you are unable to read your sd card via a card reader on a pc (not via phone usb cable) in order to delete partitions and recreate them, its best you get a new sd card

how sad. btw. Thanks :good:

My computer also once was not able to read my sd card but minitool partition wizard detected it.... What i did then was that i deleted all the partitions and created a new one with
Label--Android-SD
Type - Primary
File type -- Fat32
After i did this .. My phone and computer both read the sd card...
Hope this helps for u too..
Press thanx if it helps you

I think that's not the problem, i use a MP3 player with USB
If you plug your sdcard on linux-based using anything it should be /dev/sdc
Do a dd if=/dev/sdc of=/home/[your user]/Desktop/sdcard.img
After that install WinImage http://www.winimage.com/
Open the img with winimage it will tell you where to connect,
choose first primary fat32 partition open menu -> extract all with subdirectories, :good:

[Q] How to move apps to sd card in Lenovo A1000L-F?

Hello
I try link2sd, Lucky Patcher and AppMgr ||| but all of them detect USB storage as external SD card. Is there any other way to move app from USB storage or Internal storage to SD card? I root it.

Did you prepare the storage in the right way?
1. partition fat32 // 2. partition ext4 (Both must be primary partitions)

Yes, SD card partion is fat32 and usb storage is ext4 both are primary and not logical.
Thanks for your attention!

You need 1 physical storage that you split! For example split internal OR external sd card fat32/ext4. But not one storage fat32 and another ext4.

My phone can't mount the SD card (Meizu M2 Note)

I have the Meizu M2 Note, and i have recently I bought a Samsung SDHC card 128GB.
When I first use it in my computer (with an USB adapter) i formatted it to be a NTFS (didn’t know back then that Android OS doesn’t support it), of course my phone didn’t recognise the card.
Then I formatted it to be an exFat file system and my phone couldn’t mount it either.
So I turn to use third-party softwares to turn it into FAT32 which failed as well, even tried to make partitions (4 of 32GB - FAT32) and I couldn’t do it with “Paragon” (it didn’t succeed formatting the other three partitions).
What can I do? my phone just won’t recognise my SD card!

Hi,
Are you using Windows? If yes, insert your SDHC card and format it to FAT32. If this doesn't work, you probably broke your SDHC card. But you said that you bought it recently, so I think that you still have guarantee. Good luck!

Hey, first I want to thank you for your quick reply, but I can't format it to FAT32 without using third party software (only has two options: exFat and NTFS), and when I tried to format it with the third party software it didn't work as well.
It can't be broken because it works just fine in my computer.

OnbekendV said:
Hi,
If you are using Windows, you don't need third-party software to format your SDHC card. Just insert it in your computer, since you have said that your computer recognised your SDHC card. Then open Windows Explorer -> This PC -> Right-click on your SDHC card -> Click on format -> Choose FAT32 -> Choose format. This should solve your problem. If this doesn't work, go to windows.microsoft.com/en-us/windows/convert-hard-disk-partition-fat32-format#1TC=windows-7 and follow these steps. Good luck.

Download this tool (best partition manager for Windows): http://www.partitionwizard.com
Now select your SD Card and format the partition on it to ext4 and try on the phone.
If it does not work with ext4 try with ext3.
Remember that in that program when you make all the changes you want, you have to press the apply button.
If it still doesn't work try factory reseting (and backing up of course) and formating options ext4, ext3, exFAT, FAT32 in that order (they are from best to worst).

Does Android support ext4? I know windows doesn't right?

[Removed]

@Ori5800
Yes, android does support ext4.
@OnbekendV
The only reason I see to format in FAT32 is because Windows supports it. It is slower than ext4, holds smaller partition, name and any other size.
I would reccomend ext4.
