can someone please help me to set a2SD on MiniCM7-2.1.9 becouse i have big problems with that, i have set saving to external memory, also formated card to ext4, i dont know what is the problem, it transvers applications to SD, but not in ext4 part, but in fat
Thank you in advance.
Hey this is not a problem! when you set to save the apps in external memory the app sent to fat partition, because the ext4 partition is like extension of the internal memory. Set to save the apps in internal memory (the apps go to ext4 partition) and all is fine!
ok, tkanks man
Hello, I'm hoping someone can answer a few questions I have regarding the format of the SD Card for the Android system. - Apologies if this has already been explained on this forum, I did a search but didn't find anything too useful that answered my questions.
(I have knowledge of the linux file-system and swap drives, just unsure of the benifits of this for android).
Currently using a 16GB SanDisk Class4 SD Card.
I'm aware that you can format the SD Card to use as a swap-drive and for use of ext2 file-system.
While searching for info on this I found the following xda link which simply explains how to do this:
http://forum.xda-developers.com/wiki/SD_card_partitioning
My questions are:
1. What are the benifits of having the ext2 file-system? (Would apps stored on SD Card run faster etc?)
2. Do I need to keep a FAT32 partition (as opposed to just having a swap and ext2 partitions without any FAT partition).
3. Does the swap drive greatly improve performance. And is this worth doing on a Class4 SD Card?
Thanks in advance!
Hi.
at the first I must say swat will decrease SD card life.
i recommond you to create EXT3 or EXT4 partition.
1)one of the benefit of EXT partition is your phone storage will not full and its help your phone performance.
2)yes.of course you should have fat32 partition for eg:music-movies...and other files.
3)yes.swap is a very good.and it helps your phone ram.eg:when you play plants vs zombie at the first screen game will exit because of ram and swap will use like ram and its good for gaming.
Thanks for the reply, much apprecaited.
Are you sure I need a FAT32 partition though? Videos, music etc etc can all be saved to ext2/3/4 on a linux OS so I just assumed I could just do away with FAT32 all together?
Is the following just not the same as using an App2SD app?
"1)one of the benefit of EXT partition is your phone storage will not full and its help your phone performance."
Sorry for being a bit fussy but I'd like to fully understand what the Ext/2/3/4 partition is actually used for. Is it just used purely for storage?
Thanks again!
In a short summary (and assuming you are using a Kernel and ROM supporting the features) ...
- "Swap" on a swap partition has its own own "filesystem". The data structures are actually created by "mkswap" and the partition is not directly accessible by the user. If your phone runs low on physical memory unused parts of the memory will be swapped out into the virtual memory to make room for other apps.
Note that this is no "magically increase your RAM" solution. Once swapping occurs it actually slows down the system as the swapped out memory regions need to be copied back into physical memory, sooner or later. It may only help to run "RAM hungry" applications.
- "SD-Ext" is a, most likely, ext2 formatted partition to where Apps you move to the SD (either by Android or App2SD) will go. This increases the amount of apps you can possibly install, but doesn't resolve the problem that apps having widgets or apps that are started during Android boot-up need to reside in the internal phone memory.
- The /sdcard partition where all your user data is being stored should be kept FAT32 (for the simple reason of making a backup of your data by slapping the card into card reader easier - Windows can't read Linux filesystems by default). Some ROMs will allow you to format /sdcard ext3 or ext4 ... the advantage is that ext3/4 (if the mount options are correctly set) may perform a lot better than FAT32, though your mileage may vary.
Roger? ...or do is something still unclear?
Many thanks B.Jay - I'll hit the thanks button after I post this reply! You cleared up all my questions, but just going back to the FAT32 partition;
I use linux as my main OS, so accessing the EXT format partition wouldn't be a problem; Do you know if all ROMs would work without a FAT32 partition and replace it with EXT2/3/4 partition? If you're unsure I can always find out by formatting and loading a rom.
Thanks again, you've been most helpful!

Linux would, of course, be able to mount a ext partition (even on a SD card put into a card reader).
As for the ROM ... it depends.
The Stock Kernel Modules AddOn of GingerDX introduces ext3 and ext4 modules for the SEMC Stock Kernel, so in theory (I didn't test it!) you should be able to access /sdcard when being formatted ext3/4 - though it could be that you might need to adjust the vold script to properly mount the partition. The modules are mainly for supporting the sd-ext partition for "Apps-to-ext3/4-partition-on-mSD".
There's also alfsamsung's Alfs Kernel which is compatible with GingerDX and some other ROMs. That would be something you could try as well.
Simply look through the ROM threads ... I think MiniCM7 (+nAa's Kernel) should be able to support it, though this could involve some tinkering.
Personally speaking, I only have a ~2GB sd-ext on the SD in my X8 and the rest is a normal FAT32 partition (/sdcard).
yes you need a FAT32 partition.
when you partition your SD card you can move moveable app and games to ext partition.
please dont move app wich they cant move to ext partition.
cause after restart app that you moved to ext will corrupted.
good luck.
Thanks again! I think I'll follow your trend and try the 2GB SD-ext and the rest FAT32.
sd-ext missing!!
hey guys!! I've a small prob, would appreciate some tips. I normally move apps to sd card, if the app is movable by default. if the app is not movable by default, i use this app2sd by droidsail (available in the market) which force moves parts of the app 2 sd card. When I make back ups using xrecovery, i have no problem.
but when I use cwm for back ups, it gives an error saying sd-ext not found and it skips that part of the back up!! so any app I've moved by default or forced moved to sd card doesn't get backed up!! So I presume I have to create a sd-ext partition manually? How do I do it? I do have an sd-ext folder. but its not in sd card. it's in the root. (never had this prob with xrecovery though)
thanks in advance!!

Hi!
Could You give me tutorial how to make swap and app2sd on SDE?
I think I have to make partitions. First with swap. And now one partition ext4 and there will be app2sd and my files or two partitions-first with app2sd and second with my files?
My card is 10class and 8gb
Thanks

Please, tell me what is your sd class and how much gb have it?
8gb and 10class
Thanks

1. FAT32 (for you own files - music, pictures etc.)
2. ext4
3. swap
create them in this order.
cwm can do that.
format sd
create partition
swap....
wait...reboot
in terminal emulator.
type
su
a2sd xdata

To make partitions on your SD follow these steps.
1.Make a backup of your SD.
2.Enter CWM recovery.
3.Go to advanced->Partition SD card.
Now it will ask you for sizes of A2SD and SWAP.
Set them as you want.
Its Done...
NOTEartitioning the SD will erase all the data on your SD card..
Difference between Link2SD and Apps2SD
Hi Guys,
I just wanted know the difference between Link2SD and Apps2SD.
When I used Apps2SD all my user application are moved automatically to SD Card. I don't have a choice to select the app to be moved to SD.
where in in Link 2Sd I have an option to move selectively.
more over when tried apps2sd on ICS ROM ( MiniCM9.0.4 ) it wont work. many forums says the apps2sd scripts are not supported in ICS due to changes of implementation of OS.
so which one is better ? why ?
Secondly which iotion is beeter for swap ?
Swap partition or Swap File
1. I know Swap partition allows to use even if phone is connected to PC where as swapfile will dismounted if you connect ot PC.
but if I use ReadaheadKB setting of SD card in devices section swap file will perform more faster ( as it was cached partially) vs. swap partion
( ReadAheadKB helps to perform sequential reads more faster )
even if SD card wear & tear is more with SD card. th cost for SD cards are down so drastically that one can afford the loss of SD card ( laugh: data on SD should be backed up frequently :laugh:
Cheers!

Hi,
I am one of the many people who have defective internal memory on their P1000..
I managed to partition an external SD correctly for holding an android Kernel (MIUI).
I just want to tell the kernel not to mount the defective internal memory anymore (because it behaves unpredictably).
Is there a method to do this (like in linux removing the entry from /etc/fstab) ?

Hi, i have a problem with installing apps, my internal storage is only 2gb and it runs out od memory, every time i need install big application i need to move all apps in internal mmc manually. So do you have any EASY solution to make my internal mmc my default storage for application?? Pls pls thanks!
