Hello,
I have secondary partition on my SD card with ext4 filesystem on it.
With help of Link2SD i can use this partition for installed apps.
So the question is, when i create a backup with 4EXT (currently installed) or CWM does it include links and actual files from the SD card?
Got also a ext and ext1 seems to be a strange mounting problem..
It works but s2e cannot find the ext patition..

Hi,
4EXT nandroid backup takes a complete snapshot of your phone system,settings,data,and apps.
It does NOT make a backup of your sd card.
So, I would think that if you restored the backup,and you had not moved the apps in your ext4 partition,then they would match up again.
Why are you using an ext4 partition,anyway?
Isn't 1 GB of space on the phone enough for you?
software logic
well,
in linux filesystem, and in windows nowdays too, any storage can be mounted anywere, so if backup software differentiate external storage vs internal storage, it probably should follow symlinks and backup application from extended filesystem as well.
it could be a feature request

Hi !
I just installed the Lag Fix in my Samsung Galaxy S GT-I9000B and looks like it is fine.
As far I understand, the lag fix patch formats the internal SD as ext4 to have more stability and speedy.
So I am wondering if the external SD card would have similar benefits if I format it as ext4 too.
I don't have a spare external SD to check it my myself, so if anyone could provide any information, would be nice.

Hi
I have an external sd card and i want to have a second partition in ext4, to put somme date on it (larges files)
i read and test since 15 days and what i can said is
you need to have a first partition (primary in fat32 on the sd card)
the second partition in ext4 is not seen by android os !!! I mean, there is no way to mount automaically these partition at boot and use it.
I have found a old lagfix from mimocan which mount external ext4 , but it is to store applications as we do in sdcard. I do believe we can use for data but it is old now we have kernel and rom with ext4 in native mode and i don't find how use ext4 on external card for data instead of program (with link2sd for exemple)
link2sd or app2sd only works with internal sd card !

After you create a partition, it needs to be formatted to be usable. If you created the partition on your SD card by putting it in your computer, you have to format it separately. You use your preferred software to format, and you must specify how you want the new partition formatted.
If you create a partition on your SD card through your phone's recovery (i.e., CWM), it will automatically format it. I think CWM uses ext4 by default.

Does CWM support external SD card formated with ext3 or ext4? I considered exFAT and NTFS but none seems to be supported by CWM.
CWM can read partitions which have been formatted ext2/3/4 in your computer. I'm not aware about exFAT, and I highly doubt any recovery would recognize NTFS.
Hi guys!
I have installed CM10 Alpha4 on my i9003. The question I have is this:
Can I reformat the internal memory to EXT4 using Linux (gparted), or I have to use some script/CWM?
I currently have:
1. System partitions in YAFFS2 (made by the installation of CM10 Alpha4)
2. Internal memory in FAT32
3. SD in FAT32
Since I only use Linux I was thinking in using EXT4 on my phone, because I like Linux's file systems (and, of course, all its advantages)
I'm assuming the SD card will not be a problem if I reformat it using gparted.
Thanks in advance!
If you're talking about system partition, I'm afraid MTD partition doesn't support EXT4.
If you're talking about internal memory(which we can store data inside), I think can, found some article about this but you need to use some apps though.
EDIT: it seems like our phone won't mount EXT4 partitioned sdcard, so you will need to use some apps like app2sd to do the trick to actually store data in ext4 partition.
Oh, what a shame... but, hey! That was very helpful and I learned a lot. Thank you! :good:
EDIT: ops, I read it before you edited it. Yeah, I thought we were not talking about the same partition. It's the internal memory.
Hi,
When I instal Link2SD and open it for the first time it asks for the file system for my SD card second partition and I select ext4, but after always gives this error message "Mount script cannot be created".
The rom I'm using is CyanogenMod 10.2 by Rashed97 and Kernel 2.6.35.10.
Anyone can help me with this please, I tryed many things but didnt worked.
Problem resolved...
I've updated Superuser and rebooted the phone and after link2sd created automatically a new script and mounted the sd card properly.
Cant know exatcly what was the reason but worked.
But now I'm having another problem, Whenever I try to converte to User App I get this message "Failure - pkg: 7cache/download/****.apk Failure [INSTALL_FAILED_INVALID_APK]
Anyone can help me with this?
Mount script cannot be created.
If you store the Link2sd application in your memory card, it will not able to link to SD. Move that application to internal storage and use ext4 as second partition. It is working in my Samsung Galaxy 4.
solved for me
i had the same problem but got it resolved by....
connected the SD and phone using USB cable
backed up my files
i formatted the SD card created 2 partitions using Mini Tool Partition Wizard Manager, one with FAT32 and one with Ext4
exited the Mini Tool Partition Wizard Manager
DIDN'T safely remove the hardware from the taskbar
DIDN'T turn off USB storage
DIDN'T detach the USB cable from the PC
turned off the phone by the power button and disconnected the usb cable.
turned on the phone and opened the Link2sd app and chose ext4 and it created the mount script successfully
Hi all, same here, cannot create mount scripts.
MicroSD 32GB, recovery TWRP v2.7.0.0, rom CyanogenMod 11.0.0-RC11-p500.
Formatted SD-EXT (1024MB, no SWAP partition) in ext4 and now ext3, the mount scripts are not working.

Tried ext4, ext3, ext2 and even fat32... Not one of them works.
There is an app similar to Link2SD but working?
Or how can I use SD-EXT to extend the space for apps?
Thank you.

same issue here
Had similar problem also ("invalid argument" message). Problem in my case was that my CWR formatted to ext4 by my ROM do not want to work with ext4. So I used "mini tool" and formatted to ext3. Connect in CWR to PC and format , reboot, create script, ....
I solve the problem by not using the SD-Ext.
I'm guessing that this is something none of you are aware of as I don't see it mentioned in any of your posts...
Link2SD will fail if there isn't enough free space in /system.

For others who find their way to this thread
It appears this is an issue specific to the device - and that is an "unknown" until you try. I tried the above also - with minitool partition manager and easus partition manager and none of the partitions worked with Link2SD. Then I downloaded and installed app2sd (all in one tool) on the device and used the partition tool included with it to reformat the second partition. Be advised the app2sd version from google Play was full of absolutely ridiculous ads that I had to constantly escape and back out of or "X" out of at the top right or left corners - to get back to use the actual tool itself.
1. Ext2 format failed with an error (tried it twice even after wiping the partition)
2. did not try Ext3
3. Ext4 formatted successfully - but the mount script of Link2SD STILL failed
4. FAT32 formatted successfully - AND the mount script of Link2SD worked
I then uninstalled App2SD - and hopefully all the ads it brings
It should be noted even after successfully getting Link2SD working - it could not "move an app" to the SD card because it reported the device - a Teclast x70R was using "emulation" - but Link2SD reported it could "link" and move some files to the SD of some programs. I suspect the reality is the FAT32 file system has something to do with this as it cannot carry the permissions needed by UNIX type Operating Systems.
Others have said the EXT file system partition must be the first partition on the SD card; and while this had proved to be true with a PC hard drive when trying to install OSX as a dual boot Operating System - on my Android device it simply resulted in the SD card being unmounted - or failing to mount at all
It should also be noted that the minitool and easus partition managers COULD NOT successfully format the second partition of the SD card apparently either - because Windows technically only will recognize the first partition on a removable SD card type drive - apparently true even though they both reported successfully formatting the partition - when in fact it was ONLY AFTER reformatting using the app2sd partition tool did I get meaningful error messages - and/or that the FAT32 format of the second partition actually worked in Link2SD
It is another example of "go figure"
Hello everyone.I made the sd card partition but now I do not have any songs or anything inside SD .They have all deleted or what?Please,tell me what to do so i can restore them.Thank you
When sd partition is made, the sd card is formatted during patitioning. & there is no way to recover files afterwards.
Yes, you can restore them provided that you haven't used the sdcard much.
Use Recuva for windows or TestDisk for linux.

if windows ain't detecting anything, that means you've created the first partition as ext 2/3/4 (which is wrong partitioning), the first partition should be FAT32 and primary, and the second small partition should be ext 2/3/4 and primary (and i guess you're using it for swap or link2sd etc), and after partitioning, if your windows is detecting properly your first FAT32 partition then you can restore deleted file using Recuva or tune up utilities (and loads of other softwares), recovery is possible after formatting, with a bit of luck...:good: (ie those deleted files shoundt be over-written with some other files you copied to your card)
First don't reuse SD card to save files and try with Remo Recover.
