I can´t remember correctly, but I think few days ago I was not able to read a CM ROM from my external SD card that was formatted with ext4.
So, does Clockworkmod support ext4 or does it not? I badly want ext4 to avoid the 4GB file size limit of fat32.
Thank you.
EDIT: Now I know. I have CWM version 6.x from CM 10.2 nightly and CWM cannot read ext4 formated volumes. Though I read CWM was meant to support ext4!? Obviously it does not.
EDIT2: Today I was able to mount a USB drive connected to the phone that was formatted with ext4. I do not know, why I am able to mount this ext4 device now and why I was not able to mount my ext4 formatted sdcard.

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 want to use link2sd and already partitioned my sd card into ext4 and fat32. Can someone point out a thread that explains how to do so? All i've found is for the sgs4g and other phones
I hope this is appropriate for the Development forum as it relates to the two recoveries here - CWM 6.0.1.4 and TWRP 2.3.0.0. I have previously posted in both those threads. I have not seen any comments about problems so it would be good to know if I am not alone.
I have the 64Gb version of the TF700T with JB (unfortunately, no NVflash).
I have been using the Sandisk 64Gb UHS1 card. It came formatted with exFAT and was one of the few that worked OK under the original firmware. I could not get either CWM or TWRP to see the card at all in recovery mode.
I found a spare 16Gb card that was formatted in Fat32. That worked fine and mounted without a problem under both CWM and TWRP.
I then did a full format of the 16Gb card under Windows 7 to exFAT and it would not work. With CWM I tried a simple backup and got 'Can't mount backup path'. Then tried to Mount /sdcard and got 'Error mounting /sdcard'. In TWRP I could not select or mount the card.
Next I did a full format to NTFS. With CWM I still have the same problem. With TWRP it allows me to select the card and it can be browsed in TWRP's File Manager. However, when I try to create a backup I get an error creating backup path.
Is it just me or can no one properly mount and backup direct to the external card with CWM or TWRP when the card is formatted in exFAT or NTFS?
As the 64Gb card cannot be formatted with Fat32 then does that mean I will not be able to use my 64Gb card and backup direct to the card?
TIA

EDIT: The precise error I am getting from TWRP is 'E:Unable to create folder: /external_sdcard/TWRP (errno=30)'.
It has to be FAT32 for some reason. I had the same issue so I bought a cheap card just to have an SD Card with my nandroid backups on it.
NTFS mounts as read only in TWRP which isn't all that useful but that's due to the kernel. exFAT has a much stricter license than regular FAT so I doubt that you will ever see exFAT support in a Linux kernel.
Maybe I will dabble with the kernel config & try to get NTFS to mount writable.
What about ext4, is it possible to format in ext4 and have android recognize it and the recovery... just a thought since Linux does support it and IMO ext4 is superior to fat32 and ntfs.
Moved to correct board (hint, unless you actually POST development, it doesn't belong on development......)
"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.
