Introductory Remarks:
- Ext Partition is only needed if your rom uses App2SD+ (Froyo app2sd works with basic Fat32 partition)
- "Install apps to sd" (ext) must sometimes be configured in your ROM, check the thread for your rom for infos...
- Backup your SD card before you start ! The following steps will wipe the contents !
- Ext partitions are only visible in Linux = Windows can't see it.
- Swap Partitions are no longer useful.
- You can check if you have a working ext partition with Quick system info (in app market)
- On first reboot after partition, android will move some apps to the SD, this will take a lot of time. Some people have reported a bootloop on green HTC Screen, one reported a need to Battery pull 4 times before it finally worked), so be patient!!!!
- If the device is plugged into a PC when you try to boot with the partitioned SDCard it never gets past the white HTC sceen & logo.
Now the tutorials:
A. Easiest way is to install Rom Manager:
1) install rom manager
2) choose partition sd card
- 512mb ext
- 0 swap
3) let RM do the rest... ;-)
- I believe Rom Manager (as of end of July) creates an ext2 partition, therefore if you want ext3 or 4, easiest is to go through Gparted, or if you have amonRa Recovery, I believe this function is present.
B. Another one is using Gparted:
(copied this from http://wiki.cyanogenmod.com/index.php?title=Apps2SD)
You can use a livecd of GParted, or use it from within Ubuntu (vid: http://www.youtube.com/watch?v=sVK-t...eature=related)
+ You can do this using your phone to mount the SD card or a Card adapter directly connected to your computer.
1) Connect your phone to your computer (or use an SD Card adapter...., in this case skip to 4))
2) Pull down the notification bar and mount the phone
3) Start Gparted
4) Gparted will search available drives. (Your phone should show up as a USB drive, and will be something like /dev/sdb1 or /dev/sdc1, etc..)
Warning: double-check you've not selected a hdd by mistake!
5) In the upper right corner, select the correct USB device for your phone. (i.e. check to make sure it is correct size for your SD card)
6) Right click on each partition and select 'unmount'
7) Right click on each partition and select 'delete'
If you know what you are doing, you can re-size the partitions and add a new 2nd partition formatted as ext2/3/4
8) Right click on the big gray bar (should say unallocated x.xx gb) and click 'new'
9) Enter configurations
Free Space preceding = 0
Create as = Primary
New size = [don't touch]
File system = fat32
Free Space Following = 512 (or whatever you want)
10) Click add
11) Right click on the big gray bar (should say unallocated x.xx gb) and click 'new'
12) Enter configurations
Free Space preceding = 0
Create as = Primary
New size = [don't touch]
File system = ext3 or 4 (recommend ext4)
Free Space Following = 0
Click add
13) [CHECK AGAIN you are working on your SD card and not your Hard Drive!!!!] Click edit, then 'Apply All Operations' to write changes to disk
14) Quit GParted
15) Unmount your SD Card
16) Reboot your phone and wait (see introductory remarks)
C. Recovery Images
Some Recovery Images also have a option to format your SD card from the recovery screen. (see http://forum.xda-developers.com/showthread.php?t=721792).
I have not tried that.
As long as you have an ext2/3/4 partition and the ROM you're flashing has A2SD support (check before you download the ROM), you are not required to do anything more.
D. How to check if it worked?
To check whether A2SD is working once you've flashed your ROM,
1)Download Quick System Info from the Market, and check under A2SD Storage, it should give you enough informations.
2)download the Android Terminal Emulator app from the market and use the following commands
Code:
su
ls -l /data
You should see your app directory pointing to /system/sd/app and app-private pointing to /system/sd/app-private (courtesy of ikkokusenkin)

related thread: http://forum.xda-developers.com/showthread.php?t=731432&page=2
F. Open Questions:
What I don't know:
- If the size of the ext partition matters (if you have to choose 256/512 or 1024, and can't have 600mb for example?
- What ROMs require ext partitions? (all with app2sd+, basic froyo app2sd doesn't require ext partition).
- If Class 6 SD cards really are that important (some webpages say that class 2 cards are not able to handle ext2 partitions and end up bricked.
- How to manage the contents in the ext partition when changing SD Cards... (do you need any management of your ext partition?) or you have to reinstall those apps????) See here.
- How to check if you bricked your sd card...
- etc...
Good Luck

Use Rom Manager
Completely painless, took less that 2 mins to do mine
PS - It may appear to stuck at the HTC white screen after completion, I just left it and
it booted up normally after about 3 mins
50 apps installed and 132MB spare!!

The first time round the Rom manager worked for me. But I again formatted the card thinking i had not followed the right partitioning so i tried again but i get stuck on a black screen with SU request written forever which needs to be force closed.
Please advise. thanks

I recently bought a 32gb sandisk and want to get that working heres what I have done with no luck:
I inserted the new memory card and it picked up fine on the phone then I went to rom manager to partition the card, 512mb and 0 swap it reboots but only stays in clockwork mod, from here I dont know what to do.
If I connect the phone to the computer with the card mounted it displays the card as raw not fat32 but music files drag and drop and easily play.
I could format it from the computer to fat32 but I'll wait and see what you guys say.

Try to format the card back to fat32 using:
http://panasonic.jp/support/global/cs/sd/download/index.html
Then check out the Windows way of using parted to partition
http://androidandme.com/2009/08/news/how-to-manually-partition-your-sd-card-for-android-apps2sd/
After partitioning I use clockworkmod to upgrade ext2 to 3.
And you can't always set a linux swap of 0 so calculate 1MB for that part.

I got it to fat32 but then the windows way of using parted to partition seems difficult. How can I tell if I have partitioned my card successfully? How can I partition using clockworkmod only, when I go to partitions menu it only says mount or format, this is frustrating...

gparted has a live cd to partition your sd card
http://gparted.sourceforge.net/download.php

Hi, i see you all set swap as 0 does that mean its using phone internal storage as swap how fast is read/write of phone ram ? i have class2 32gb card i used the phone boot with the r5 windows.bat to get into it and i set 256 swap/512 ext2/ rest 32bit all seems to work fine.
i note that writing to the sd card is about 2MBps and read is 10MBps.
i have a class4 8gb that writes at 10MBps reads about 17MBps i have had both in the phone and i cant say that i notice lag on the 32GB but i havent had it more than a few days and coming from xda orbit its a big difference.
if i use the card as storage the phone becomes very lag but maybe thats cause in that mode it would have no swap file? might change that when i finally flash to froyo.
gparted kept saying it was unformatted when windows said it was formatted so i gave up with it.

Thanks, but I think I sorted it. Fingers crossed.

Just rooted my htc desire and used rom manager to partition my sd card (the one I got when I bought the phone). Everything fine.
then I bought a new Transcend micro sdhc 8GB... this memory card is not recognize by windows if using card reader. So..:
- I inserted into blackberry and connected using usb cable. My windows (Windows xp) can see and access it.
- formatted the new memory card to Fat32
- copy Open Desire and and Official Sense Froyo ROMs, both by Adam
- flashed to Sense Froyo ROM, and when it rebooted, it freezed.. cant get into the system
- flashed to OpenDesire, it worked.
- Download ROM Manager
- choose "Partition SD Card"
- Swap 0, Ext 512mb
- ERROR...
what should I do?

Did you download Clockworkmod recovery through ROM Manager before that?

If you create a partition using rom manager do you lose all your apps and settings that you already have in use.
thanks

yes.. cos when i clicked partition sd card, it asked me to download clockworkmod first.
it goes to recovery screen but with "unsucsessfull" message. cant find sdcard/cache/update.zip ...
the funny thing is, if I copied update.zip from my old memory card into new one. and run update.zip from recovery screen... then it worked.
but when I checked with quick system info, app2sd only shows around 400mb. is that rite?

Its showing around 400mb for me aswell, but how exactly can I tell if it is working. If I go to manage applications and click on sd card I have a couple that I moved over i.e rom manager but some apps are unmovable to sd card. Are these apps unmovable by design. I hope I haven't done it wrong.
BTW neophyte is the best rom I've used yet.

If so, how do I do it?!

Formatting of the memory card.

Hi sorry if this has been answered but couldnt find it.
i recently purchased a a bigger size micro sd card for my htc desire. The phone will not turn on with the card in, nor can i format it in the recovery memory. Can someone tell me what i need to format it as on computer. GPT MBR, FAT 32. etc etc. Thank you

I used Gparted in Linux to set up the standard layout:
- 32MB SWAP
- 512MB EXT2
- Rest FAT32
You can download a livecd of Gparted, or use "Partition SD Card" within ROM Manager.

You can download GParted for Windows aswell. Google it.

Or you can flash amon ra recovery and use that to partition within the recovery.
Also rom manager allows you to partition the card as well. I personally use 0mb for swap and 768mb for ext3. Do note rom manager only allows you to use an ext partition no bigger then 512mb. I assume it only formats it in ext2. My opinion is amon ra recovery is the way to go. Use version r5 as the latest is quite buggy according to other users. Or you can use gparted as mentioned earlier.
Misunderstood your post, use gparted. I didnt read that you cant turn on the phone with the card in it.

swap is not needed

It's already been done.
Can't hurt, though.

I'm also having a little problem with the partitions...
I have a 32gb card, but when i remove it from the card reader after making the partitions (or after disconnecting the phone from the computer) the only partition remaining is the FAT32...ext and swap become unloccated space :s
how can i fix this?

You do realize that you can't use the SWAP and EXT partitions as drive-space, right?

yes, but i'm not talking about the space...the entire partition itself dissapears. for example, if i'm going to flash a rom that need an ext partition it won't flash...the ext partition is gone

one question,
should the ext partition be in the front or at the back of the FAT32 partition?
or it doesn't matter?

How to create ext3 partition on SD-Card under Windows

This post is for people scared of Linux (like me)
I finally found a way to partition a SD-Card under Windows. I tried more tools, but only one was able to work with SD-Cards. Here's what you need to do:
1. Download and install MiniTool Partition Wizard (google it, i cant post links)
2. Resize original FAT32 partition to make room for the ext3 one. If you have enough space, the data on the card shouldn't be affected, but make a back-up just in case.
3. Create the ext3 partition on the space made available and apply changes
The first partition should be FAT32, and the second ext3, make sure you have them in this order.

Almost all custom partition managers can do this in Windows-Partition Magic, Paragon, Or Gparted with VMWare

They can, but not on SD Card. Windows doesn't support partitions on memory cards. I tried Partition Magic, Paragon, Easeus, none of them work.
I didn't try Gparted with VMWare tho, you might be right about that.

Paragon works for me on Windows..And Gparted is what I use

Strange, it didn't work for me (see attached pics).

Just install the latest ClockworkMod, or Amon-RA and do it through recovery.

It's useless, you need a ROM that supports it.

quick question - if I create an ext3 partition using this method or any other way, and then move the apps I had on SD (the old way) back to internal, will it then move them to the ext3 partition automatically? I just want to make sure I have this right myself before I attempt it.
I'm using Oxygen 2.3 ROM RC-6 which supports apps2sd etc.
thanks in advance for any replies.

I'm using 9.0 Pro, you're using 10.0 server, if that helps..
I still prefer Gparted though..On Vmware.

The a2sd+ script is built in, it executes at installation. Best way would be to use Titanium to backup ur froyo a2sd apps, wipe+install a2sd+ custom rom, use the option of Titanium, to move to sd.

and how do you want to put data on the ext3 partition ? ... you will need linux, its the best way...

I use miui rom, xpart(data2ext). the script works, but the phone is slow as ........
someone any idea?
i also have a 8 gb card, same partitions, but no problem..
any idea how i can tets my 16 gb card?

Minitool is crap. Haven't used easeus but its still under Windows, which is a no no
Gparted is the only decent tool that will nicely partition an ext partition on your sd whilst aligning it properly. This is both my personal and professional opinion.
Now because it doesn't run in windows, its a bit more long winded but so much more worth while.
Virtual machine (vmware player) is the best method. There is a link to a guide to set this up in my signature

Heeeellllppppp,

Do you actually need the swap partition? Maybe you should just try to get link2sd running first.
And did you create your ext4 partition as a primary partition behind your fat32 partition? You could also try to use ext2 instead of ext4.

Problem
Ext4 is primary of course, ext2 not so quick as ext4, so what i shoul do?
So I have another one question, does Widfire s supported ext4, i use eoghan kernel for android 4, and custom rom by djoliver

Ok...

So I got a diffrentsd card, went into CWM recovery and If you go into the advance u will see something like partisioning. So if u go in that and select all u want and that should work... try to create 1gb or less... Since more than 1gb doesn't seen to be working well. After its done reboot and go to link2sd and it will see the partision so then u can select... ;D
Good Luck

P.S. Delete the curent 2nd partision before doing it, delete it with mini tool. If u want to see some magic flash data2sd.zip and u should see that the partision will be made as the internal memory and it will go there instead of linking ;D

Question
Thanks James I ll try it, but what the ext number created in recovery? EXT2? Or another?
Sd card wil formated?

Amm... I think ext2, but its better than nothing
P.S.: EXPLORE the recovery mode and you will find out more

Thanks
Thanks I do this

Can't you just use the Partition Wizard in ClockworkMod Recovery? Let's you choose your EXT size (upto 4GB) and a swap size (which i usually do 0M)...
Gl.

I also got the same problem with minitool partition wizard...ita useless in my case. So i tried partitoning with cwm which u cando by selecting partition sd card in advanced menu...it creates an ext2 partition. I suggest you to use cronmod's INT2EXT script as it seems far more better and easy than link2 sd!
Hit that "THANKS" button if i helped you...

If you use a INT2EXT Flashable mod, then also partition from the Recovery too

Please answer the following questions to be able to help you better.
1. Do you have a working sdcard installed on your phone ? (silly, :silly: but important)
2. Have you made the appropriate partitions on your sdcard ? (usually 3 partitions are required; 1 fat,1 ext and 1 swap)
3. Does your kernel have init.d support?

Since you are using CM11 by Olivier, I believe it supports init.d. No issues there.
So, the reason CronMod script is not working for you is that you don't have appropriate partitions on your sdcard. CronMod script "increases" your internal memory by basically mounting the external sdcard partition as your internal memory. For this to be possible, sdcard should have a partition formatted as ext2/ext4 file system.
In simpler words, I would recommend you to create atleast two partitions on your sdcard both primary. One of them should have ext2 file system and the other fat32. (ext2 will be mounted as internal memory and fat32 will be your "normally" usable sdcard). Having a swap partition is optional.
I am running CronMod Int2ExtV2+ Script with following partition scheme on a 4GB sdcard.
Partition1- fat32 (2.5 GB)
Partition2- ext2 (1 GB)
Partition3- swap (512 MB)

That's not right. The first partition have to be FAT32 for use as sdcard and the 2nd one will be ext2/3/4. Just reverse Partition 1 and 2.

Well, at the time of posting, I didn't mean that to be in any order. That's why I posted the link on how to create the partitions. But anyways, it can be confusing, so I changed it. Thanks.
