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.

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 had originally created a sd-ext partition of ~600 MB using MiniTool on Windows 7. However, recently I observed that the 2nd partition is not being shown at all, by MiniTool, Windows 7 Disk Mgmt or GParted.
Using the recovery I was able to partition the sdcard and bring the sd-ext partition size down to 128MB, but I am still unable to completely delete it.
The built in SDCard erase option too is formatting only the FAT32 partition. Is there any command line I can use within android itself to completely delete the sd-ext partition?
Resolved: Miraculously, Windows finally detected my card as being unformatted and a quick format got the job done.
My cresta has a system partition (/system), a data (/data) partition and a sdcard (/mnt/sdcard)
And a mounted (/mnt/external_sd) external SD kart (8Gb)
The data (/data) partition is only 1 Gb and the rest of the internal memory is used bij the mounted sdcard partition. The data partition is allmost full and I can't move anymore apps to the sdcard (not all of the apps are movabe)
I can mount a external sd-card but I can't use it for moving applications. I only can move to the internal sdcard.
I want the internal sdcard (/sdcard) removed and the 2Gb added to my data partition.
And the mount of the (internat) sdcard witch is removed must be set to the mount /external_sd
I'm a newbie, so can anyone help me to change this?
There is nog data or apps on this tablet (Cresta CTP818) and I have a backup of the Original rom (tested to restore)
So I can try whatever I want.
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
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.
