So I bought a new Samsung sdcard. The sdcard automatically formats into f2fs if I try to use it as adoptable(Internal) storage. I don't have any problem with f2fs bit seems like my device or ROM doesn't support it (Random reboots and bootloops). I used the sdcard as portable as fat and ext4 and there Werner any issue. I previously had another sdcard which would convert into ext4 while using as internal and it didn't have any problems.
So can I change the sdcard's default file system so that it would convert into ext4 instead of f2fs if used as internal ? Any help is appreciated.

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 !
regards
I have kingston 32gb memory card, class 6.

Anyone knows where problem might be?

hi
looks like you want to do the same thing than me but ... as i learn at this time, there is no way to use ext4 partition on external sd card, just with some tools on internal sdcard.
android doesn't have script and code to mount under /mnt ext4 partitons just FAT32 !!!!!!!! great
"Use EXT3 Filesystem For The SD-EXT Partition,To Avoid Any Errors While Backup" Thiz is the suggestion from developer. But I dont know how to do this

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.
i try to copy 4GB file into lenovo a7-10 but i found that it's does not support exfat (as i used on my G3)
I formated second partition on sd card using EXT2. When I installed link2sd pro, I selected the use of secnd partition as ext2 and saw info about problem. Whe I selected EXT4 , it works good all time to today.
Is it EXT4 over EXT2 ? Or EXT2 was reformated to EXT4 in the background , I do not know.
