Hello,
OEM's rom doesn't handle ext4 for external storage and asks for reformatting to exfat, telling it is "corrupted".
Manually creating an exfat first partition and a second ext4 partition doesn't work to vold mount the partitions, but mounting manually works for using the filesystem, yet the system aggressively asks me to format the whole storage.
How should I proceed to format "correctly" my sdcard to make vold stop ask me to format, yet keeping a whole storage ext4 partition, or a small exfat partition and a big ext4 partition.
On device tools that touches /system are outright banned as it will break safetynet stuff. (But root is available)

Hi everyone,
I have project in mind but all i did to realize it didn't work.
my project is: i want to use the sdcard with 1st primary partition for saving Roms and updates to work with cwm (fat or fat32), 2nd prim. part. for my data aka "/mnt/sdcard" (ext4), 3rd prim.part. for apps using Link2SD (ext4) and last, optionally, 4th prim. part as SWAP (swap).
this is because i want to use ext4 for /mnt/sdcard but cwm can not read ext4 to backup/restore roms. i tried something with vold.fstab, and init.local.rc, init.rc, /etc/init.d/ but i couldn't achieved the goal.
can anyone help me achieve this?
thx
i'm using CM7 (CyanogenMod-7.1.0-MADTEAM Gingerbread 2.3.7) SD 8GB
512 MB (FAT/FAT32)
6 GB (EXT4)
1GB (EXT4)
128MB (SWAP)
i found a manner to make the first primary partition visible only to cwm: i made it hidden fat.
so android looking for the first usable partition of my sd to mount as sdcard. also by a script i can make swapable the last partition, but this is an option as it is not always wise to have a swap partition.
but some problems remain:
-android forces mount in fat32 for sdcard
-link2sd forces to mount the 2nd partition for its purposes, and it cant because the partition is already mounted as sdcard in fat32. link2sd has to mount the third partition for linked apps.
ok my sdcard is not seen on my device what made it unseenable is that i wanted to use ext3 so i deleted all partrion,wiped sdcard,made 3gb fat32,300 mb swap and 300 MB ext3 now my sdcard cannot be seen i went into mount in cwm and used mount on all options but still not on phone seen and root explorer says its not mounted i can see all my data on sd card on my pc using card reader and i use my fat32 partition primary and other 2 partitions logical please help me asap and thanks in advance
ALL partition should be PRIMARY - not LOGICAL.
Backup your data and format it in, then create those partitions in MiniTool Partition Wizard
- FAT32 (primary)
- EXT3 (primary)
- LINUX SWAP (primary)
but must warn you -> there is possibility that you will have troubles with automounting EXT3 or SWAP...

swap is already mounted bt ext3 I can use A2SD IN settings right?
pic of what im gonna do in attachments plz see it
ok i did it what i didi is attached screenshot and im booting it up now
On my Archos 101IT I formatted the (removable) SD card as ext3. This was required for TitaniumBackup. When UrukDroid is booted, it mounts the file system as:
/dev/block/vold/179:17 on /mnt/storage/sdcard type ext3 (rw,nosuid,nodev,noexec,noatime,nodiratime,fmode=0 666,dmode=0777,errors=continue,data=ordered)
I do not want the fmode/dmode since these make it impossible to protect files on the storage (again, as required by TitaniumBackup).
Where can I change what to have this file system mounted with the right options on reboot?
ANSWER:
Urukdroid has a special script, /system/bin/mount_sdcard.sh, that mounts the SD card upon boot. This script understands (V)FAT and EXT4. Anything else is left to the vold automounter. Archos modded vold so it could do a bit more than stock A 2.1 vold, e.g., mount EXT3 file systems.
I upgraded the file system on the SD card to EXT4, and now mount_sdcard.sh mounts the SD card upon boot with the correct mount options.
Thanks to $aur0n for helping me solve this.
Upgrading an EXT2 or EXT3 file system to EXT4 is easy, see https://ext4.wiki.kernel.org/index.php/Ext4_Howto#Converting_an_ext3_filesystem_to_ext4 .
So ran out of storage in /data partition, decided to create 2 partitions in my external SD and i created it using Gparted, one is ext4 and the other is fat32, now the phone refuses to mount the ext4 partition from Link2SD.
Looking at the vold.fstab file and sysfs paths(/devices/platform/mtk-msdc.0) , it seems that our phone can mount only 2 (+1 otg) partitions ? (or is it just 2 sd cards ?)
is it even possible to mount the second partiton ?? (No /devices/platform/msm_sdcc )
I do know of the EMMC method, i don't like it ;p
A block for the second partiton is present in /dev/block,(mmcblk1p2) gonna mount and see what happens

hi, gowtham121
ROOT your phone first,
create 2 partitions as fat32 on sdcard
its work on my chd:fingers-crossed:
Does the /data partition encrypted by the default full disk encryption? Also, does partitions that are mounted in /data be encrypted as well? I have a partition that i created on my external sd card, which is used by Link2SD app, and it is mounted in /data/sdext2. Will that partition be encrypted?
