Ok if I do a sd card partition what are the benefits from doing this action?
What will happen?
What are the pros and cons from this?
If I do a sd card partition will it delete everything from my sd card?

Copy contents to your pc. Format sdcard thru phone. Flash amon recovery. Boot into recovery, partition thru recovery on your phone.
App2sd allday. No cons

Benefits is extra space for programs.
Like the poster above me said, copy everything off your phone on to your PC and use Amon Ra's Recovery to do it all for you automatically.
It will not ruin your phone or sd card.
You'll be fine.

It said on rom manager that it cold do it. What sizes should I have? Ext size 125? 256? 512? And swap size? 32 64 or 128?
Somebody help?
Sent From My HTC EVO

it's really your choice. If you want more space for your apps, make the ext partition bigger.
the swap partition (i think) really shouldn't be as important for a evo (as it's got plenty of ram and processing power), but you might as well make a 128 swap.

Well I mean can't you already out apps2sd already Without partitioning?
But what happens to the other 256 half of my memory where will it go?
Haha sorry.
What do you use tho?
Sent From My HTC EVO

meh, I'm not too familiar with 2.2's apps2sd methodology...
my SD card is still formatted from an old MyTouch 3G Slide, with like a 256 MB ext and 64 MB swap.
neither partitions will actually be "visible" when you mount the sd card, unless you view it in linux.
the space that you use for the ext and swap will be taken away from your total GB.
so if you have a 8GB card, and partition away (theoretically) 512, only 7.5 GB will be accessible to you.
I say go for it, if you think it'd be nice to put apps on to an extra partition for more space and not having to worry about whether that app is still usable and functional when you mount your SD card.
And the swap partition... I know how useful it was with older phones (like the G1) and how essential it is with almost every linux distribution, but I really can't confirm or deny any benefits it would have on an Evo.
it certainly wouldn't hurt it (i think 0-0) but I can't say it'd help too much either.
I think you could at least give it a shot. If it doesn't do anything, then you haven't really lost much. If it helps a lot, then you've gained something. If something goes wrong, it's rather easy to get back to normal.
Hope that helps.

Ext partition with Evo

So i know on my magic i always had a Swap partition, EXT, and fat32...
Seems like when i got my Evo, the SD card only had a fat32 and no EXT.
When installing custom roms, Should i just go ahead and reformat the card with EXT or do we not need it on the Evo. From what i know of the EXT partition and working with my magic for so long, i would assume it still needs to be there but it was just odd that it wasn't there from the factory when i got my phone.
TIA
IMO, a2sd isn't necessary on this one
I have almost 60 apps installed (including the behemoth Google Earth), yes I know how ridiculous that is, and I still have over 200MB internal storage free.
The EXT2/3 and Swap partitions didn't come stock on your Magic, either.
It's up to you. Like nebenezer said, it's really not necessary on this device. The only reason I'm running a2sd is so that I don't have to mess around with reinstalling all my apps when testing out new ROMs. That's really the only reason at this point why a2sd would be an advantage. In fact, unless you're using a class 6 SD card (which the provided card is not), it actually probably slows down the phone a bit when launching applications.
Ahhh.. So EXT is pretty much only for A2SD? Thought there was some other info on there...
And i know what swap is..
Cool. THX

pretty much, you can move dalvik to sd and I think data/data too but like CentroniX said unless you have a c6 or greater card your better off skipping a2sd on this phone.
Not having to reinstall your apps is convenient but when I flash a new rom I wipe EVERYTHING anyways. I always like to start with a clean flash so if there are any problems I know its not one of my apps. Plus titanium backup makes it very easy to restore everything.

How to use A2SD?

Hi,
I would like to know how to configure it.
I have in my SD:
1024M for swap
1500M for ext2
5000M for Fat32
Sent from my HTC Desire using XDA App
Swap? On a Desire? Don't think you need that, there's plenty of RAM.
So you need to partition your SD card, 512 mB ext3 should be plenty, the rest can be FAT32.
FAT partition must come first.
ok, thank you.
And now how can I enable the A2SD apps ?

Once you have Apps2SD installed and your SD card partitoned correctly, all there is to do is just install your apps and they will be installed to your ext2 partition on your SD card. Use the Quick System Info app from the Marketplace, or see my thread to check if it is working correctly:

Way too much swap!! For Desire best is 0 for swap, 512mb for Ext2 and rest for Fat32
is it possible to partition the SD card "outside" the phone?
I got a new SD card I want to use, and the old one is running as ext partition, and the phone spasses out if i swap the 2 cards? so how can I make the external partition so I can install on the new one?
Yes, you could try partitioning by accessing Recovery Mode via your PC while having your phone connected with the USB cable. Use the relevant push files (available for download in my sig from the Nimbu guide) to access Recovery Mode, then you will see an option to partition your SD card. You can set the swap, ext2, and FAT32 space of your SD card and convert it from ext2 to ext3.
As advised above, set your swap to 0 MB, ext2 between 512 MB - 1024 MB (max), and rest of space allocated to the FAT32 partition.
Remember to backup your SD card contents beforehand otherwise you will lose everything through partitioning.

I'm on r3.1 rom with A2SD+, I'm really pleased with it but I plan to switch to some Froyo rom once htc releases it (with A2SD+ if possible).
What is the proper way to prepare sd card for change of rom ( now I have sd card with standard settings: swap 0 ext2 512 mb fat32 rest).
Do I need to format it again?
The thing that I need to switch between goldcard and my everyday card during the process makes it difficult enough

With DJ Droid's v1.0 R1 BETA rom (Sense with Froyo), it allows you to partition your SD card the exact same way you had done with the r3.1 rom. I have mine setup with a 0MB swap, ext2 size of 512 MB, and rest to FAT32 partition. To install this rom, it is advised to format your SD card again to get rid of any niggling bugs.
AFAIK, all other Froyo roms (ones without Sense) require you to prepare the SD card differently and not have your SD card partitioned, you need to push via ADB to install your apps to the SD card.

This will not be possible as you need to use the Gold Card to unlock your phone's CID if your phone is network branded. After that, you can root and then flash a rom, and then partition your sd card afterwards.

Thank you buddy. I appreciate your kind words
what are the benifets of app2sd???
The title says it all, I was wondering what are the benefits of storing and running your apps from the sd card other then the obviously being able to install more apps then can be stored on the phones internal memory?
Secondly what is the purpose of zipalign? At a very simplistic level I guess it has something to do with optimizing the apk though I am not really sure what this means.
Even with my Sprint CDMA Hero overclocked to 652 (min) & 710 (max) I still find the keyboard to be a bit laggy, will enabling the above help with this at all?
Yep, by installing apps and their associated cache to your SD, it saves you from having to install them directly to internal memory, which would affect the performance of your phone with the more apps you install. With A2SD installed, you basically save storage space and allows your device to run faster.
Also, consider installing a cache cleaner app to free up more space.
Zipalign makes interacting with apps more efficient after they are optimised making them run faster with the Android OS.

I have seen the benchmark tests showing the speed improvements but I don't really see how changing the location of where the apps are installed to would necessarily improve the performance of their execution, I mean the phone's internal storage is separate from the phone's internal ram. Are there fragmentation issues or something when it comes to running the apps from the smaller internal storage vs the larger external storage of the sd card?
I think this question was asked previously but I didn't see an answer for it; when app2sd is set up, when you start installing new apps do they automatically get zipaligned and then installed to the sd card or do you have to do it manually?
Hmm.... i think you have a point there and i agree with what you are saying. With A2SD, i don't think it improves performance since it's ROM space, not RAM, that these apps are occupying. The main advantage of A2SD is having more dedicated space for storage of apps.
Since the 1.6 SDK was released, i think the ADT does this automatically on APK export. Therefore any app which has been updated since ~September (and was developed using the ADT Eclipse plugin) will be zipalign'd.
You can also do this manually, see this link:

connect the phone in "Disc Mode" copy all your data onto your computer, disconnect, change memory card to the new one, and copy and paste to the 16 gig.
Sorry I don't know any way of moving you games or apps when changing an SD card
hope this helps! good luck!
Wow, is it that easy, thanks a lot! Can someone help me about the games/apps ?
sorry to dig up this topic, but since I searched for it, here goes:
Same issue, I am changing from 8GB Micro SD to a 16GB micro SD, the catch: I am using A2SD+ and my previous 8GB has ext3 partition, so do I simply backup, change card and copy back the files or do I need to partition the new 16GB card like I did the old one, and then copy my backup?
if you want to save your ext as well, then this is best done via amon-ra recovery.
do a nandroid + ext backup of your rom with your old sd card.
put in a new sd card, formatted with ext, restore nandroid + ext then your rom and ext will be fine.
As for the fat you will have to copy as outlined above (via a pc).

isnt it that the the nandroid backup will be stored in the SD? if so then after I do a nandroid backup, place the new blank SD and do a nandroid restore, then if it looks for any backup, then it wouldnt find anything because the old card isnt there?

The folder "clockworkmod" stores the Nand backups. You need to copy this to the root of your new sd card. This will be detected by Clockworkmod automatically

This is what I did them I got a new card, I had this in another post so just cut and pasted, my solution to moving to a new card. Bering a new member I can't post the link in here, but here is the copy of it here.
My setup, 2GB no class listed MicroSD, HTC Desire, Rooted with MoDaCo r9, with A2SD. All of my apps are on the MicroSD pretty much.
Well the MicroSD came in and I did what I know how to do, I used a cloning program that I use all the time for PCs, figured what the hell it should work.
- I plugged both of the MicoSDs using the SD adapter, then plugged the SD adapter into an SD to USB adapter and plugged them into the PC.
- I used Acronis True Image 2010 Acronis True Image , did an exact clone (called "Disk Clone" in the Acronis software), from my 2GB MicroSD to the 16GB MicroSD. Did NOT adjust any partitions or anything, had 14GB of free unused, unpartitioned space on the new card.
- Then I took the new 16GB MicroSD and plugged it back into my phone, booted, and it worked great, the phone can't even tell that it's a new MicroSD, shows same sizes and everything, as I didn't adjust any partition sizes yet.
- Then I took the MicroSD back out, plugged it back into the PC, then used another product of Acronis, called Disk Director Disk Director and then went in and expanded/resized the FAT partition to the full size, it used the free unused space to do that, and moved the partitions down the line and expands the FAT one in place.
- Plugged the card back into my phone, booted, worked great, got 15 GB plus of space now on the FAT partition. All the apps works, everything works great. It seems a little snappier and faster when loading apps now.
Side notes:
I just happened to have both of these products installed on my PC and use them all the time so that's what I used, but any Disk Cloning program that supports USB will work.
There is plenty of other "cloning" programs out there, like Norton Ghost - not free, some other pais ones. But also bunch free ones as well a list of them here , wiki list of them as well. Some of these programs are LiveCDs, which means you boot your PC of a CD and then you can edit HDs, also the USB Drives, other like Acronis will have a PC program as well a boot disk. With acorns I was able to use it just as a program no booting of a CD.
I personally have used this program called "hdclone" which is free, it has one limitations but it really is not a big deal in this case, it limits the copying to 1 GB per minute, hell for 16GB card thats 16 minutes !!! so not a limitation really. So do a exact clone using HDclone, don't resize the new SD just leave it as is, this worked for me, I think leaves everything exact as possible. Another free cloning program I have used in the past is DriveImage XML , so either of these will work to clone one SD to another. Now to resize, the product I use ALL the time to resize drives is "gparted", this one is a boot CD, so all you gotta do, plug in your SD card using the USB, boot of this small GParted CD, select your drive and then expand the FAT partition. Few extra steps with some free products but it works if you're not able to acquire Acronis.
Hope this helps, let me know if you have any questions or problems. Sorry for the long write up but haven't seen anybody describe doing this plus some people aren't as familiar with cloning HDs as others.

It's a known issue with Clockworkmod. Go back into Clockworkmod once again and restore the backup you just made. All will be well.

what can i say? very detailed!
the only problem is that, I had to download Acronis product demos before I can do all these. I do imaging before but I dont resize EXT partitions...
ANyway Im still downloading..
Although I think it would help if anybody can post free and lighter (below 50MB, I guess) of softwares that can do USB cloning (disk cloning in general),..
I will post here my results..
HDclone is pretty small program and it should do the job.

So far, this worked for me.
1. Backed-up my old 8GB card on my PC (the FAT partition).
2. Did Nandroid + Titanium Back up. (The Nandroid will backup the EXT partition)
3. Formatted the new 16GB with FAT32 on my PC
4. Resized the 15.++ GB of FAT32 to 14.XX GB so that the 1GB goes to the EXT3- I did this via a bootable GPARTED CD I got here: http://gparted.sourceforge.net/download.php
5. Copied the Clockwork MOD folder from my PC backup (see step 1) to my new 16GB card.
6. Inserted the new 16GB to my phone and booted into ClockworkMOD recovery
7. Did a NANDROID Restore.
8. After restore, I had to shut off my mobile and I removed the card coz I needed to copy back the whole FAT partition backup from step 1 to the new card.
9. Placed the new 16GB back and voila!
(NOTE: steps can be interchanged,for example, I think the copying of the FAT partition done in step 8 can be done after step 3 above.
Anyways, hope it helped.

[Q] How Do I Remove An Ext3 Partition From My Sd Card?

I was using my 4gb sd card for apps to sd for my previously-rooted android phone, and had about a 500mb of it partitioned to ext3. I have since unrooted my android phone and put it back to stock, but in doing so, I lost the recovery console that would allow me to unpartition my sd card. Is there a safe program that will recognize the ext3 partition and remove it?
Gparted. You can use a live cd or a VM.
Hi there. I downloaded a free program call minitool partition wizard. Do a google search for it (I can't post links)
It has worked well for me with my SD card partitioning.
Make sure you back up the contents of your SD card before removing the ext 3 partition as it will delete all the contents on it.
could you please elaborate a little as i am a noob. like whats gparted? whats a vm? whats the process of doing what i asked? thanks for the help.
I don't know if Windows recognises it at all but worth a try really. Gparted is a live cd tool that allows you make partitons on a storage device. I think that VM refers to a Virtual Machine, using something like VMWare or VirtualBox.
guys please help. i used these softwares but none of these is showing my ext3 partition in the program window. just a 3.22gb of one partition on phone. the 512mb of ext3 partion is still missing and i dont know where to find it.
Well, since you really don't need the ext3 partition anymore, you could format the whole SD card from windows (do a back-up of the content on the hdd before, though). Then in Windows (I'm guessing you're using windows ), with the phone connected in mass storage mode, right click on My Computer / Manage / click on Disk Management and you should see in the list of the drives your SD card (pay attention to the size). Right click on the 512 MB partition - Delete volume... After that you should create a new partiotion, format it as FAT32... Or you could delete all the partitions of the card and create a new volume.

The partition may be corrupted. You can still try to use Gparted live cd - google for gparted-live-0.7.1-5.zip . It can also be installed on USB flash, check their site for instructions. Restart your PC and boot from the CD or USB flash then check your sd card. If it still doesn't recognize the 512 partition, you might be out of luck.

how could the partition be corrupted because i was using the ext3 partition to install apps when i had root. it was only recently that i have to sell out my htc desire and i unrooted my htc desire. unroot procedure was done successfully but the card is only showing 3.22gb, i-e, 512mb is missing. this may become an issue if the buyer does not want to pay for a 4gb card with only 3.22gb of storage. it should be around 3.5-3.6gb
A partition may become corrupted if you remove the battery from the phone while the system is still running (i.e. writing data on the partition), it is not unheard of. Do try the gparted solution mentioned before, though.

yes buddy i have tried the gparted solution you suggested before. even that is showing only 3.22gb of my sdcard and no mention of the 512mb ext3 partition. i dont know whether i am doing something wrong or what.... ???
Anyway, is there anyway i could recover that corrupt partition? Like can i ROOT my htc desire again and then try to format the ext3 partition from the recovery? i read somewhere there is a way to do that in recovery by giving some commands. and once i have recovered the ext3 partition space then i can UNROOT my htc desire again. DO YOU THINK IF I DO THIS ITS GONNA BE OF ANY USE? Please help me.
This might work since it worked for me. 4GB mysteriously disappeared from my 16GB card and neither Windows or gparted picked it up. The only way I was able to get it back was putting it in my phone and the Android picked it up. I did have to format my whole SD card but nontheless, I got all my space back. Hope this helps and if you have tried this then I can only guess that your SD card is buggered.

um actually, my sdcard IS in the phone this whole time as i dont have any card reader. i am connecting my phone with my pc in hard drive mode.
from within the phone, i have tried to format the sd card many times but the space does not go beyond 3.22gb..
Something seems to have messed the partition up. Have a look around on the web

ok tell me if i root my cellphone again, will it help?
because there is a way to delete the ext3 partition from the recovery.
finally recovered my ext3 partition.
this is what i did.
1) rooted my phone.
2) enter into clockworkmod recovery
3) mount sd-ext (i guess it wasnt mounted that's why no app was recognizing it)
4) now windows was able to recognize the ext3 partition.
5) problem solved.

Oh man, I had EXACTLY the same problem and was driving me nuts. I searched high and low everywhere and couldn't find the answer. Thank you!

Hi there. I downloaded a free program call minitool partition wizard. Do a google search for it (I can't post links)
It has worked well for me with my SD card partitioning.
Make sure you back up the contents of your SD card before removing the ext 3 partition as it will delete all the contents on it.

this worked.. thanks a lot
i had the same issue as the OP
Use a card reader and MiniTool Partition Wizard.
Delete all partitions on the SD card and create a new one that fills the entire SD

SD card ext and swap partitions: How useful? How large?

I'm using Mimicry 1.4.0 and quite happy with it in general. I've figured out that 4EXT is the way to go, and have ensured that all my internal partitions are ext4 (just now actually, I'm interested to see how much it helps). I have seen various people suggesting repartitioning of the SD card as a way to see a significant performance enhancement as well, and this seems reasonable to me but certain information on the matter seems to be lacking. There's a few posts here and there on the subject that have additional detail, but they're in other device forums or in response to folks running different ROMs..
So:
How helpful is repartitioning?
Should I just create an ext1 partition? Is ext2 additionally helpful? What about a swap partition?
What do the damn things actually do?
How large should I make the partitions? I assume there's a point of diminishing returns.
Since I am a cheap bastard, my cheap SD card is likely quite slow. How do I tell how fast it is? How relevant is that?
Much thanks!

I'm also interested to know if anyone using swap has seen any performance improvements.
When you make for example 128Mb ext4 and 256 Mb swap partition to your sd card for G2 and plugged in it. Stock rom will not use the swap file but stock rom will detect the ext4 part and use it for keeping the cache there.
and for the custom roms like CM series and Sense roms you'll need to make a swap partition and if you like ext4 partition on sd card. (ext4 is not necessary).
Because G2 and desire Z has 368Mb ram and these new custom roms are needing a bit larger space then stock rom. thats why you can use " swap_enable_v2" for additional ram using. ( Remember if your sd card's write speed more then 6 Mb/s ) of you can simply use some scripts like SuperCharger_V6 or some other like this.
I stongrly suggest you to use Swap enabler and SuperCharger_V6 at the same time like me. it increased my desire z's permormance more then %40 and it awesome now.
:good:
Well, I'd say swap partition does not always is a good idea - constant reads and writes of the specific part of the card may degrade it's performance.
That's why I'd suggest trying DataSwap, which can just create plain file on the card.
I'm using it for over 4 months now, and I'm pleased.
On the side note AFAIR /sdcard should be FAT, and not EXT4
Partitioning the sd card or creating a swap file on sd card is not so different. Still mskes alot reads and writes

If you are using ICS/JB - I put my swap file on the /cache directory since it doesn't seem to ever get filled up. Then I am not using the sd card.
