SD Card Partition sizes with Apps2SD

Hi everyone,
i was just wondering about what partition sizes I should set for my memory card using Apps2SD as I am a little unsure. I am currently using a 8 GB SD Card.
I was thinking to set it up with a 32mb swap, 512m-1gb ext2, and the remainder as fat32? Is that suffice? the ext2 size I assume is the space I would dedicate for the installation of apps.
Then after that, should we convert ext2 to ext3?
Please advise
Thank you.

I wouldn't use swap at any time. Your phone has 578 MB of Ram - I don't know how much is left for the running system after the substraction for radio, 3d,.... but it still should be around 400MB. Using swap would just slow down your phone.
A 256 MB ext partition for programs is enough.

Kind of depends, I will for sure get a bigger partition then 256MB, some games are 20/30MB in size. Will be nice to not worry about those anymore!

I just installed apps2sd then started installing was I meant to do different? lol

Hello guys,
I'm a newbie with Android.
I've not understood: with A2SD I can "migrate" all apps to sdcard or there is a way to choose what to have on the device and what to have on sdcard?
Thanks,
ghale

I have this question too. are all the apps going to the sdcard or you choose where to go ???? or when the phone memory fills the sdcard is used ???
and another question I have is if the sdcard apps are copy paste backup able

I have read that if set to 0, no swap partition will be created. The default is 32MB.

Im not using a swap.
I just created my ext2 using gparted on Linux. I resized the original fat32 and then used the free space to create ext2. No data was lost on original partition after resize

Hi there,
im not a big user of apps and won't end up installing many to the sd card. Would you suggest I set up the partitions as follows:
0mb swap, 512m-1gb ext2, and the remainder as fat32?
I have also read that if you convert EXT filesystem from EXT2 to EXT3 after partitioning, it results in better stability/performance, and by converting the EXT filesystem from EXT3 to EXT4 results in best stability/performance.
Can anyone clarify this please?
Thanks again in advance.

EDIT
Found it !

This is where i'm getting confused... this article, for example, states to allocate 32 MB to the linux-swap partition, 512 MB ext2 partition, and remaining free space as a fat32 partition (for an 8GB SD Card).
It also states this is the most common setup...

I used 980mb for my a2sd not swap and everything seems to be working just fine

Im just thinking... the Android OS is designed to do this for you, when it runs low on free memory it starts closing apps based on a ranking system for deciding which is 'least important' to avoid actually running out. If you later switch back to an app that the OS has removed from memory it will be reloaded from internal storage which won't be as quick as if the app was still in memory, but on the other hand it won't be any slower than if it was being loaded into RAM from the swap partition on the SD card.
Actually, I can't see swap helping... Either the Android OS will avoid running out of physical memory as it's supposed to and never actually use the swap partition, or worse it does actually use it as if it was extra physical memory (unlikely, I think) which will interfere with the sophisticated memory management scheme that's already there. Is this the reason why Android phones don't ship configured for swap? maybe because the OS is already doing something better that makes swap unnecessary?

As long as you followed the correct procedure (accessing recovery, installing the Apps2SD.zip file via recovery and set the partitions), then you are set.

Well, what would be the point of installing Apps2SD then if you did not allocated extra space to the ext2 partition

You will not need to hard reset, just access recovery again via Linux and select the option to Partition the SD in recovery mode, enter the partition sizes you want, then you may want to select the option: convert ext3 to ext4 for improve stability/performance. Yes, use the Gold Card SD.

Utilizing ext partitions on the sdcard with the G2

Hey folks,
I spent a long time searching, but I can't seem to find an answer. I'm using my sdcard and the partitions I created from my G1. I'm running low on space on my sdcard and I realized that the ext partition is not being utilized.
I tried to move some apps to the sd card using the native apps2sd (settings > manage applications) but it seems to be moving it to the main FAT partition and not the gig I set aside as ext.
Before I repartition it and get merge the ext partition with my main partition, I wanted to know if there's any point in having an ext on the G2. If so, how do I take advantage of it (for apps and cache)?
Its an 8gb class 2 sandisk with r/w speeds of over 10mbs. Aside from the gig for ext, I also have a wee bit set aside for swap, which is just about useless now - right?
Thanks for all your help!

Jury is still out over the need for swap with the Desire Z,some say it makes a difference but what is clear is that with the swap partition enabled,on Unity at least there is a display bug on widgets,I would say that the phone runs ok without it.

I don't mean to be rude, but I don't care about swap. The G2's performance is great. I am concerned with space and before I merge the ext3/4 partition with my main FAT partition, I wanted to know how to utilize that gig I set aside as ext.
Thanks again.

Ok but you did ask about the swap partition being redundant or not,anyway a gig ext is a waste of space with this phone so repartition and make it smaller 128mb or 256mb should be more than enough

When I was on my rooted stock u20j I used a app called 'Link2SD' which made use of the ext2-partion to store apps on... Maybe try looking at that on the market?
Good luck!

I had an ext partition with a2ext on my G2 but honestly it wasn't needed. I have a ton of apps and still have just under 1 GB of internal memory left.
Swap, as I'm sure you're aware, is pointless on this phone. Compcache is about the only thing I'd use and even that is debatable.

No, it won't use the ext just Fat32.
Instead of the market app, use darktremor's A2SD script. You have much more functionality with it. It also can use ext2, 3, and 4. There's an app that I'll try to locate on my computer for you that gives you a GUI to control it all once you have it installed and active.

[Q] What does partitioning do?

I've seen posts mentioning partitioning but what is it?
and what is the Swap size?
and does it really improve speed and such?

If you want to use link2sd or similar then you need at least two partitions on your sd card, I have a 1gb ext4 and 512mb swap. The ext4 is for link2sd which, to simplfy it, uses part of your sd card as an extension of internal memory meaning an ability to install more apps or leaving more internal memory free; the swap partition is for linux swap, which won't make a huge difference, maybe only noticable if you use your phone heavily.

Using cwm will wipe your sdcard. Use Linux, or on windows use partition wizard.

I'm using the Link2SD and I can move system apps to the partitions, but is this safe to do?
Like if I plug in my USB to my pc and I have an important app in teh partition will it just crash my phone?

Android will only unmount the first partition. The second partition (which is used by Link2SD) will not be touched, so everything is safe.

Would moving everything off the internal memory save battery? or would it have no effect?
and if the SD cards read and write speeds are faster than the internal memory would that make it faster?

If you have an sdcard that has faster r/w speeds than internal memory then yes. If that's possible...

[TUT]How to Create Partition in SDcard/MicroSD for Windows user

hello guys,
i wanna share to you guys how to make a partition in external sdcard/MicroSD for Windows user. Dunno if this already post in XDA, didn't do a research
just to remind, do this with your own risk!
now, what we need :
1. PC/Laptop
2. microsd/sdcard with capacity 2gb/4gb/8gb/16gb/32gb
3. microsd adapter or card reader.
4. Minitool Partition Wizard http://www.partitionwizard.com/free-partition-manager.html
there's another tool called gparted but this tut only use Minitool Partition
5. a ciggy and a cup of coffee
before we go through, don't do this while you're drunk, so sleepy or in hurry..
now, i assume that the minitool partition already installed on your pc/laptop and the sdcard is empty.
let's begin....
1. put your sdcard into adapter or card reader
2. open the minitool partition wizard software.(pic 1)
3. right click in sdcard (pic 2--i use 8Gb) and click delete. after that your sdcard will look like pic 2-1 as "unallocated" (becareful to choose the drive!!)
4. right click and click create (pic 3)
5. in create new partition choose "primary" (dont use logical) and change the "file system" to "Fat32".(pic 4 & pic 4-1)
6. in partition size you change to what you need. if you want to swap 1gb then change the "partition size" make your "unallocated space after" to 1024mb(pic 4-2).
(i dunno exactly the space that fit with but i use 1gb, if you dont know either you can ask to our dev or mr. pep) after that click ok
7. now you can see the 1gb seen as unallocated(pic 4-3)
8. right click and click create again at the unallocated(1gb) will be a warning that "the new created partition cannot b used in windows" click "yes" (pic 5)
9. now change the "logical" to "primary" (if you choose logical then your phone will probably got a black screen or black screen with battery icon+lock icon after you flash a new cusrom) (pic 6)
10. Change the NTFS to ext2/ext3/ext4 (if you want to install link2sd/s2e from market you can choose ext2 and/or ext4, for me i choose ext4 because i use s2e) and click ok. (pic 6-1)
now there are 3 operations pending in the left side (pic 6-2)
11. click "apply" and "yes". (pic 6-3)
12. now take your ciggy and drink your coffee and wait 1-2 minute untill the successfull pop up then click ok(pic 6-4). close minitool program.
- this ext* will not shown on windows, only on linux base OS.(you can see it on Windows by using some software, i.e : linux reader or raise data recovery, etc)
- use sdcard adapter/card reader
- if you wanna move your app just use link2sd or s2e free on market.
- in this tut i use ext4 just for example to you guys if you choose s2e, but it is not a must for you to choose ext4,.for faster read/write sd choose ext2(see post 2 by pep)
this is just a tutorial for those who dont know and dont understand how to make partition/swap and for those who dont want to swap the phone's internal<-->external. do this before go to Pristine Method
swap thing is too risky for class4 microsd,
credits to :
- minitool partition wizard (useful tools)
- mr. pep (this guide related to Pristine Method ) http://forum.xda-developers.com/showthread.php?t=2044861

- XDA
if this help just click the Thanks button if there's something i forgot to write or i'm wrong please correct me..

Great tutorial!
If I may, I'd like to add some tips:
When making the very first partition (from an empty-card condition), make sure:
It's Aligned to MB instead of Cylinder
There's a 1 MB 'gap' in front of the partition
Also, make sure that all partitions' sizes (in sectors) are divisible by 256 (or, in other words, the partition size is a multiple of 128 KiB).
.
The reason for this is that some SD cards allocate their storage capacity in 'blocks', and the largest known block size is 128 KiB (128 * 1024 bytes). 256 sectors = 128 KiB. By ensuring that all partitions' sizes are divisible by 256, you are ensuring that no block is split between two partitions, thus keeping performance high (as the SD card no longer need to read a block and perform a seek just to find the beginning of a partition), and help lengthening the life of your SD card.
.
(Other SD cards might have smaller block sizes, but all a binary fraction of 128 KiB, i.e., 64 KiB or 32 KiB or 16 KiB or 8 KiB or 4 KiB. Thus, if partitions are multiples of 128 KiB, they are certainly multiples of the smaller block sizes.)
To ensure that partitions are divisible by 256, just before you click on the "Apply" button, do the following for each partition created:
Right-click on the partition
Choose Properties (the bottom option)
Click on "Partition Info" tab
The size of partition (in sectors) is "Last Physical Sector" - "First Physical Sector" + 1
For example, in my case (see the attached image), the "Last Physical Sector" is 29003775, while the "First Physical Sector" is 2048. Thus, the size of the partition is 29003775 - 2048 + 1 = 29001728. Divide 29001728 by 256 and you have the nice integer value of 113288, meaning that the partition is an exact multiple of 128 KiB.
As for the filesystem type for the second partition, I myself prefer ext2 because I reasoned:
This is an SD Card; employing journaling (implemented by ext3 / ext4) will result in too much writing -- shortening SD Card life
Writes are (nearly) instantaneous anyways; journaling are helpful if writes take some time to finish (e.g., writing to a spinning disk, which needs the track-seek and sector-seek plus track-shift plus ECC generation)
The only way a write to SD Card can get interrupted is if power was removed immediately. Aside from dropping your phone and inadvertently ejecting the battery (in which case, SD Card corruption should be the least of your concern), smartphones can't suddenly lose power. When power gets too low, Android performs an orderly shutdown ensuring that all buffers are flushed
ext2 code in the kernel is simple, making reads & writes faster, and less intrusive to foreground apps (no need to generate/manipulate a checksummed journal)

thank you bro for rhe additional tips..i forget bout that.. that'very useful for us.
yes, ext2 is better to choose..
i use ext4 because i install s2e not link2sd..and sometimes ext2 cannot be read by s2e but it's not a must for everbody to use ext4..

did you swap your internal sd-external sd after partition to ext4 and using the app(i.e link2sd or s2e)?
what apps that you use to swap?link2sd or s2e?what app tools (beside those two app) that you use?
it wont get hardbrick if you follow the tut carefully,,
i do this with my 4 microsdcards, 2microsd with size 8gb, 1microsd with size 4gb and 1microsd with size 16gb and all of it just class4.

Hi stpdkid.
Okay,I've got a 32gb class 10 SD card.
I tried doing the partition last night.
It the SD card which I had been using on my Xperia Arc for nearly a year so you can imagine the amount of garbage on it.
Copied everything to my PC and went ahead with the partition.
First partition Primary/ Fat32/9gb
Second partition also named as Primary/Ext2/21gb.
Done.
Copied my files back onto the sdcard and inserted it back into my device which only recognized the 9gb.
Used link2sd and it reads only the first partition of the sdcard.
I think I did everything correctly.But why is it that I'm missing the 21gb?
Should I have named it as NTFS/Ext2/21gb?

I've googled a lot to find a way to format the second partition in any format other than FAT32 which allows for app linking but not data linking , I tried to format the second partition in all ext formats (2-4) but no use the Link2SD cannot the second partition .

First of all, wrong section.

I think Xperia M kernel does not support ext partitions.
So you have to download kernel source and enable ext partition while building the kernel.
If you don't have enough knowledge on how to do so, search here for already made custom stock kernel (I don't know if there is one)

Maybe you are using hacked link2SDplus aren't you?
You can't link apps using patched link2sd, alternatively you can use original link2SD then patch it manually with lucky patcher afterwards.
It works for me in latest cyannogen ROM and ext4 as my second partition filesystem.

I can confirm what @allrested just wrote, ext4 second partition on 64GB card works fine with Link2SD. Been using it that way for over a year on a stock ROM with rooted Kernel on Locked Bootloader. (Both Android 4.1.2 and 4.3)
Pay for the Plus version of Link2SD and you can write data to partition too. Have 1.7GB free on my internal flash.

I'd like just to confirm that you have Xperia M Dual so that I wouldn't purchase the software then find that my kernel doesn't support ext4 partitions , specially that I tried with the free version and it didn't even mount the partition all together

I have an Xperia C1905.
I'd be surprised if it makes a difference, but fair question.
Update
I also have an Xperia C2005 (now) and again, I can confirm Link2SD with a ext4 partition works fine.
Using the paid Link2SD version you can clean most application data off the Internal NAND memory.
My C2005 only has a class10 32GB card at the moment (10.5MB write speed).
Will probably upgrade to a 64GB SanDisk Extreme Plus.
Also using Foldermount on the C2005 and C1905 without problems.
Be advised, games will still look to load data on the physical internal NAND memory, so you have to side load the game data onto the SDcard manually.
This is only required if the game data is over 1.5GB as normally the internal memory has 1.6GB+ free now.

If I remember correctly, ext2 worked with my c1905 if I selected ext4 when prompted (I know, a bit weird)
