I know from old Andoid OS threads that it was necessary to split format an SD-card in fat32 and ext3 or 4 partitions.
I now use ANdroid 4.4 and got myself a 128GB SDcard.
Simple question: is it still neccessary to reserve a ext3/4 partition for the OS ? Else I would all format to fat32

Hi there pals, after buying HTC Desire second hand I'd like to make FAT32 and EXT3 partitions... I burnt GParted and saw that those partitions exist, so no need for it...
EXT3 has 1GB (in gparted written that is 116MB used???) other is FAT32 - 8GB SD card from previous nokia 5800.
I downloaded every bigger application to test saving files, and from cca. 60mb's internal memory now I'm on 26mb's, obviously nothing goes on that EXT3 partition?
I wanna know how to make my phone install aplications on that EXT3 partiotion not internal memory which is almost full?
Thankful!
I'm using HTC Desire with OXYGEN ROM, some 8GB SDCard!
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.
I would like to partition a 4gb sdcard and create three partitions for user data, phone data and swap
The rom on the phone is nobodyAtall's MiniCM10-4.1.0 (Nightly May-18-2013) http://forum.xda-developers.com/showthread.php?t=1837273
My question is: Would be any problem using sdcard partitions as phone internals?
My idea is create partitions, change the device init scripts so the phone mounts a sdcard partition as /data and other as swap. SDCard Class 10 might not be used.
I mean.
I'm a Linux user and a Mac OSX user.
I Do NOT need fat32. I can read linux partition with my linux machine.
and linux ext format don't have 4G limitation.
I can even found ext driver for windows. or Mac
but I found that my android phone can't format it to ext,
I want my /sdcard in ext format.
Is that a solution for this?

It all depends on your phone and the default format that your phone uses. For instance Samsung use rfs (fat32) format for its stock ROM as such ext 4 will cause it (SD card) to fail, on the otherhand if you use custom ROM, it will be converted to ext 4 format when you flash custom ROM. So you need to be careful about it.
AT the same time if you have CWM, you can format your SD card too either fat32 or Ext4 format in the phone itself . so use your device specific forum to determine which ROM for your phone is capable of what format FIRST before formatting it..

Hi
I tried to create 2nd partition as ext4 on internal SDcard, 3 GB but my device keep saying that the SDcard is broken and tell me to format it. when i format it, it format the whole SDcard as FAT32.
what i did is delete the whole partition, apply it, create 2nd partition as ext4 and give to 3 GB and create 1st partition as FAT32 and give it 10 GB. my tablet does not have custom recovery.
