Partitioning the SD

Can someone please educate me on partitioning the sd? Based on what I've read and my discussions with others, ext swap is for cache, fat32 is for apps, and the remainder is for usb storage???
I have a 8 GB class 6 (supposed to be faster) Samsung sd partioned at ext swap - 0 and fat 32 - 500.
If I'm right about ext swap (please correct me if I'm wrong), I could make my phone faster if I allocated some sd space to it??? One forum I read said that the phone is usually faster but it could have been referring to a different phone and a slower card.
If I did decide to change my partition what affects would it have (wipe sd, reinstall custom rom, etc)?
Thanks for any feedback!

Partitioning the SD card allows you to utilize a2sd/app2sd and/or swap space on your SD card - if the ROM in question supports it.
Note that the ext and swap partitions are separate things, not one and the same thing.
swap is for swap - set it to 0 (you will never need it)
ext{2|3} is for the A2SD/APPS2SD space for storing applications (and dalvik-cache for some ROMs) - 512 MB will be more than you ever need.
the rest is the VFAT partition - the MS-DOS partition you see from your Windoze box when you mount it from the PC.
Note also that partitioning your card destroys all data on it - make a backup if you decide to partition.
Neither A2SD nor having swap space will speed your phone up. (Adding swap - for ROMs which support it - will actually slow your phone down, except certain pathological cases, unless you become an expert on the process trimmer configuration and experiment with swappiness controls. The reason this happens is because the as-configured process trimmer kicks in too late if you merely add swap and do not reconfigure the trimmer).
My recommendation? Keep your life simple and avoid both A2SD and especially use of a swap area on the SD card, until such a time as you "need it". You might find a practical need for A2SD if you are going to be trying out a whole bunch of new ROMs as they come out, or you are an app hoarder and run out of space in /data.
Probably you will never need to use a swap partition on your card.
Again, in neither case will you notice a perceptible gain in "performance" of the phone.

PS Josh. Please stop putting usage questions in the Development forum. Please. Put them in the General forum.

Thanks for clearing that up......and i will stop posting in development.

APPS2SD and LINK2SD question.

Hello again, I need clarification with this subject...
I had a difficult time in rooting my android, thinking I failed. so for many times I rooted, installed xrecovery, then most importantly apps2sd. but I don't think it works, then I found all about Links2sd. I installed it, and each time after installing I always select the "link2sd" option, and I check the include davlik cache, but my phone memory is continually decreasing... is this normal or not? could there be a conflict with apps2sd and link2sd since I don't know if I have deleted apps2sd. sorry I'm an android newbie. Thanks..

Well... if you had app2sd link2sd would monit about it and asked you to uninstall it first.
If you don't know if your phone is rooted, look through apps - if you have a superuser app - you're rooted
As for link2sd working or not: connect your phone to the computer and open minitool partition wizard home. It will see your ext2 partition along with free and occupied space. If there are any apps on ext2 partition of your SD card - apps are installing there and the slight decrease of space is due to the existing shortcut files. Because you have created ext2 partition, haven't you?...

I did what you said and yes I found files on the other partition I created. but problem is, some files still go to the phone memory, for example the game app "ninjump" has 15mb installed on the phone memory while on links2sd it shows that it is linked to the sd card.
also, I tried removing the memory card, and when I turned on my x8 the programs were missing, so I suppose links2sd is working.
only problem is now is that some chunks are still installed to the phone memory. is there a way of totally redirecting everything to the sd card?

link2sd: Leave data files in Internal Memory, and you can choose the apps to SD
app2sd: Copy all data from the application to the SD, It's all automatic

Ok, here's the deal - how many times did you install ninjump in the past? If more then once, and meanwhile you moved it to or from ext2 it might have (though the probability is very slight) that you have two apps - one in internal storage and one in ext2 storage.
So, navigate into ext2 partition (it's a folder in root directory - sdext or so) and look for this app. It might be hard, as names of linked apps are somewhat messed up, but there should be icons If there is no app on ext2, try switching it back to internal mode and then onto ext2 again - perhaps without linking dalvik cache.

APP2SD
I having problem with the app2sd too..i dunno whether it works...This is what i had done..I had busybox, superuser, and xrecovery installed and rooted. But when come to partitioning the sd card, i partitioned it into 3 parts : FAt, ext2 and ext3...after that i installed the update.zip and custom zip of app2sd...the phone starts not recognizing the sd partition...anyone can help here??

I use titanium backup to see app2sd works or not. if a2sd decrease, so it work.
if internal still decrease, I guess some file or even some app just can't work with app2sd.
one question too, how or can I move games data from fat sdcard to ext2 partition? like gameloft data. I need my fat space for other file

I tried navigating to the ext2 partition using minitool partition wizard, and I indeed saw files that I have installed there. so do you mean that apps2sd is better than links2sd? thanks..

Well... I'm not saying anything is better, though I used both solutions in three different ways.
For stock SE ROM link2sd is better, since you only need to partition SD card into primary fat32 and primary ext2 - nothing more. Then you install an app and all works fine.
With custom ROM you cannot use link2sd, since they all have app2sd hack preinstalled (well, you can always modify files, but what for?). Problem occurs when you have this hack AND ext2 partition. The hack then moves automatically all your apps to ext2 memory along with dalvik cache if you install them in internal storage. If you install in external storage, the app goes to fat32 secure folder and dalvik cache remains in ext2. If you don't have any ext on custom ROM, dalvik cache is always in internal storage, while you can move any non-system app onto fat32 sd card.
The ext2 solution in custom ROMs may seem convinient, but for me it was not. When you use apps like phone locator, they should always dwell in internal memory, since SD card can be easily taken out, while deleting such an app from a remotely locked down phone would require flashing, otherwise the device is useless for the thief

Well actually both app2sd and link2sd are typically similliar. I've tried app2sd before and it still leave some files in internal memory. So will link2sd. But link2sd is much more easier to use because once your phone is rooted you just need to install it on your phone without going through the adb shell thing. Easy for newbie for sure. But you just have to manually link new installed applications and games. That's what differ link2sd with app2sd. Now I'm using link2sd. If you want to make sure, why don't you try those froyo phone. Try to use the app2sd stuff on those phone. They still install some applications on their internal as well although they have built in app2sd.

[Q] about partitioning your SD card?

okay, so i just flashed Kyrillos' ROM (7.0, then upgraded to 7.1)
now i want to partition my SD card to create SWAP, and also to create a partition to add extra space to the internal memory (what is it's name, again?)
i don't know too much about what type of partition to do, so can you guide me through the process or give me a link where i can read further?
also, what are the recommended partition sizes?
PS : i have a 4GB, class 4 SD card. and i just downloaded minitool.

you can flash g3mod kernel and do partition in uer sd card.mine is 8 GB Card, Class 4...I have 1024 as Ext Size and 256 as SWAP. so the choice is uers.

I've been looking for that too , Thanks

okay, i didn't know i'd need a card reader :/
i don't have it. any way to partition it using the CWM?
and what sizes do you recommend? i was thinking maybe 128 MB SWAP and 512 as the internal memory size.
and do i have to flash the g3mod kernel? i'm currently running 2.6.32.9. this came with Kyrillos' 7.0.

wait, i'm getting confused now. when i flash Kryillos' ROM 7.0, does my kernel also get changed? or am i running the stock kernel?
and the CWM i'm talking about is just.. recovery. the one that i access using vol up + vol down + home key + power key.
that also has partition SD card option under advanced > partition SD card.
will this do or do i have to flash g3mod kernel?

Once you flash Kryillos' ROM you are no longer running the stock kernel
CWM is ClockWorkMod Recovery and it comes with the ROM and so it's different (Google it)
And about making a SWAP, well , you might wanna read this -
"1. An Android swap partition must live on your SD card. SD cards are very, very slow memory. They are 100 to 1000x slower than a SIM. They are 10 to 100x slower than a hard drive. They are marginally faster than a network connection. When an application is “swapped out” it is copied into this very slow memory, and copied back to physical memory when it needs to run. On the other hand, when an app needs to be restarted after being terminated by Android, it is loaded not from the SD card but from the device’s (relatively) fast physical memory.
2. When an Android app is terminated because of low memory, it decides what information must be persisted to represent it’s state. This can be very, very small. For example, it might be an integer index into a database. When an app is moved into virtual memory, the OS has no idea what’s important. It just moves the application in whole. It can’t be smart about it.
3. Having swap actually prevents the native Android memory management scheme from activating. The system sees memory and doesn’t distinguish between physical and virtual. It will therefore prefer swap over the native Android memory management scheme, and won’t activate the native scheme until swap is full.
4. Having swap requires some overhead of system resources."

[Q] CM9/CM7 Out of space, but computer showing 27GB available

Hello all,
I have CM9 nightly installed on a 32GB microSD and I have just run into a weird problem. I still have 27GB left open BUT when I try to download magazines and install apps, it's saying I'm out of room or running out of room. Anyone have any idea why that might be?
Is it possible it's installing things to the EMMC? If so, how do I change that?
Sorry if this a n00b question. Thanks in advance for your help.

Android has 3 major areas where stuff is stored. The system partition holds all the OS stuff plus has an area for system apps. The data partition is were downloaded apps get stored normally. The media or sdcard area is normally used for music, videos, pictures and also where some apps store any working data.
The system and data areas are of relatively fixed sizes even though they are all on the actual SD card. For your 32GB SD card it is probably "460M system, 975M data, rest is FAT for sdcard" from veryGreen post.
So your error message is being triggered probably because the 975M data partition is full. Typically this enough to hold about 150 - 200 apps depending on their size, but some games can take quite a lot.
You can check memory usage by going into settings and looking under apps.
What can you do about it? On an SD card install the simplest way is to use ANdroids capability to move apps from the standard data partition to the sdcard partition. Not all apps can be moved but many can and this will then free up space in your data partition.
Get the Apps2Sd app to help you manage this process.

I haven't run from a sdcard in quitevawhile, buy it sounds like the card didn't get repartitioned after making it into a bootable. After you burn an image to a card, you need to use an application like Easus, a disk partitioning tool (free for home use for windows, I believe) t repartition the card and make use if the remaining space.

I think the partitioning must have worked otherwise it wouldn't function at all.
You could change data partition size to give more space to the data partition if you are careful. I've done that on emmc prior to install. I've never tried it on an SD card after install and it's possible it might muck something else up. However, the basic point is that apps and related content go into data by default. The big part of the SD card left over from the initial install is intended for media.
Compare it to a phone. The data partition in the internal phone memory is fixed and can run out of space if lots of apps are installed. If you plug an SD expansion card into a phone it allows you to store lots music, video, etc but unless you move apps to the SD card then your original data space is unchanged. That's why app users can complain if a memory hungry app can't be moved to SD.

Maybe you can teach me something here. I am not sure I understand.
When I formatted an 8 gig card to run cm7.1, I was able to use it to boot but had the rest of memory unavailable for use. It wasn't until I redid the process and then reformatted the partitions to have the remaining space available. Only then was I able to use the remaining 6 gigabyte or whatever. I had the four partitions in both instances, and the card worked, it just wasn't available because all the space was allocated to the wrong partition. Which I rectified with Easus, I'm pretty sure.
What I guess I am saying, isbthat there are some tools that could be used, although I maybe wrong. It just seems counter-intuitive that the OP should have to use App2SD and otherworkarounds when theybhave 32 gigs to play with. I think Easus lets you define those partitions anyway you like, with the 29 gigs or so that is left once you allocate the system stuff.
Like I sad, I maybe just don't understand this very well, it is something I did when I was first learning about rooting, before I figured there was no real reason not to go internal.

The various partitions have different purposes. It's not that they are unavailable for use. You want each area to have sufficient room for what you want but not necessarily too big because that then is wasted and is subtracting from the other areas.
First there is the boot partition containing the boot images. This can be small.
Next you have the system partition (~500MB) which can be fairly small because the OS does not take a lot of room and the system apps are relatively fixed in size and you don't need to add extra to that.
Next you have the data partition where downloaded apps and some of their associated data lives. You want this to be fairly big to accommodate a decent number of apps but it doesn't need to be huge. Apps vary in size from 100s of Kbytes up to say 20MB or more. So a 1GB data partition can typically hold about 200 apps.
On an SD card that then leaves the rest of space for a sdcard partition where media can be stored like video, pictures and music plus some apps will also require some working space on there.
So on an SD card install the main balance is between data and sdcard. If you were to make the data partition larger to accommodate more downloaded apps then you reduce the amount of space for music, video etc. But you do want enough space to hold a decent number of apps. The standard verygreen SD card installer sets the balance at ~1GB data and the rest sdcard for media. Now if you never wanted to put much media files on the SD card and you want to be able to download thousands of apps then that would be an argument for setting the balance the other way.
Now if you install to the internal memory the same scenario applies but you have an additional partition confusingly called emmc. Your boot, system and data areas are on the internal memory. The left over internal area is the emmc partition and the sd card is now normally set up to be a single sdcard partition.
Both the emmc and the sd card are typically used to hold media files.
The size of the data and emmc partition in the internal memory can be varied before you do the install by some partitoning zip tools and there is a thread dedicated to that.
By default as supplied new Nooks have a 5GB internal data partition and a 1GB emmc. Many people think that is not a great choice as it is really difficult to run out of app space with 5GB and it means there is only 1GB internal space for media and the unused data space is wasted. By repartitoning to say 2GB data and 4GB emmc then you get plenty of space for apps and release space for more media.
You are right that using something like Apps2Sd would seem unnecessary when you have lots of free space. It is effectively a work-around to let you use some of the sdcard as extra data area if you run out of the data area that has been allocated. Actually on an SD card install there is not much of a downside in that moving an app from data to sdcard as it is still all on the same SD card. For an internal memory install it is nice to have a big enough data partiton to make moving apps to the SD card unnecessary.

[Q] Where is my memory going ?

I've xcd35 also known as zte blade. I've not installed many applications, still I see only around 25MB free space in my phone memory
What can be the reason for this ?

Have you taken a lot of photos or videos possibly and are those not being saved on the SD card?

Yes, i did took many photos but they are on my sd card.
Still I don't know where did the space go.. can anyone help me in getting back my space ?

Maybe you should install some app such as file manager from market (I can't provide a link, search "file manager", it's the first result by rhythm software). Then go ahead and select "Storage analysis" after clicking menu. It'll do a complete scan of your phone+SD-card and then shows you the biggest space hoarders.

I installed file manager and it says following,
device total memory: 162.5 M
device free memory : 24.57M
sd total memory: 1.86M
sd free memory: 1.15M
Also, it gives the biggest space holders, but all those are in my sd (like one app tak 570+ MB and my documents take 33M, both are in my sd).
the list all space holders includes the folders in sd card only.. How do I see status of internal memory ?

The 162.5MB is the total internal memory available for your apps and their data. The 24.57MB is how much of that is free at the moment. When you move an app to the sdcard, some of it is left behind on the internal memory, so you can't get rid of all of it. You can increase the amount of internal memory available by creating an ext partition on your sdcard (though it looks like you only have a 2GB sdcard, so you wouldn't have much space left for music etc. on it) and then using something like darktremor a2sd to move your apps to the new ext partition. This works differently from the normal move to sdcard as it allows you to move the whole app so frees more space.
The other option is repartitioning the internal memory. This means you take some of the space from where the rom is installed, and add it to the data partition so you can make use of it. For this to work well you need to use/be using a custom rom as the stock ones wont fit in the reduced space.

This isn't really a long term solution. The dalvik cache is needed by the phone, so wiping it will only temporarily give you more space until the phone rebuilds it all once you use your apps again. The cache partition is separate from the data partition, so wiping that would make no difference to how much space you have available.

Which ROM you are working on? It seems like you have stock ROM as you are unaware of CWM. If you are using stock rom, you need to switch to any custom rom to flash darktremor a2sd so that you can partition you sd card and install applications on them. You can get complete tutorial on installing CWM and custom rom from cyanogenmod website. You can uninstall bloatwares if there any to free your phone memory.

You need to root and install a custom rom to partition both internal as well as external memory efficiently. You can flash darktremor a2sd script that allows you to install apps on partitioned sd card to your rooted stock rom but it won't work (didn't work for me).
Almost all the custom rom come with darktremor a2sd pre-installed on it. So it is advised to switch to any custom rom. But beware, both rooting and installing custom rom will void your warranty. Once you install a custom rom, i'm sure you will love it.
You can find guide on partitioning internal memory on the following links

But i personally won't recommend partitioning you internal memory as the following ICS rom uses the default like partition.
You can follow the following link below to root and flash cyanogenmod

If you find rooting steps given in the guide difficult you can install z4root from following link and install it on your phone to root the phone easily.

Once you install cyanogenmod install "ROM MANAGER" from market and there you will find the option to partition your sd card.

I can change my sd card to 16 or 32 GB .
That is not a problem..
Now, can you please tell me how do I do external partitioning ?
or how do I do repartitioning of internal memory?

You can partition the sdcard from ClockworkMod recovery, which you need to flash the custom rom or the darktremor scripts to make use of the ext partition. Some roms come with it pre-installed, others you have to flash it separately.
You can repartition the internal memory by TPT or Windows flasher. TPT is the easier and safer method. From your internal memory stats you posted earlier, it looks like you are stock Gen 2, but download the Mr Pigfish app from the market to check.
If it says you are Gen 1, then you can use one of wbaw's TPTs from his thread on here, or you can use them from my app. Once you use one of these, you will be converted to Gen 2 as well.
If you are Gen 2 already then you are most likely stock Gen 2 and will need to use the TPT's from my app (choosing the stock Gen 2 option when it starts), from the thread I made on here, or by using the Windows flasher.

Here's a tip that I just recently discovered.
Since apps that are flashed in your rom (like Market) cannot be deleted in a conventional sense, a duplicate of the app is created whenever they are updated. I found an app called apps2rom that moves the updated version to the rom, and deletes the old version.
I got a good 10mb from that.
