[Q] any rom with data2ext

Hi all,
I want any sense rom with data2ext because then i got many MB free for apps.
How do i do this and is the speed acceptable?
Thank you!
Nick

easy:
1. root(if you havent already)
2. format sd-card with ext partition(like with a2sd but mybe a bit bigger partition)
3. install any rom with data2sd installed
and from my experience, no the speed is not acceptable. You will be much better off using a2sd+ which also gives you plenty of space..

yeah ok.
but i want many apps installed.. likely big games. and some games MUST be installed to the phone.. so with 10 apps my phone is fully full.
i always got like ~130mb internal.
but i want data2sd cause then you got many many mb free for apps.
+ when i installs an app and move it to my sd ext. it still leaves something on my internal memory wich takes space. so apps2sd still takes quite much space on internal memory.
so you all got this problem?

You are not understanding the difference between a2sd and froyo apps 2 sd. The last one being the one, where you can move apps freely.
The oldstyle a2sd+ moves both apps and dalvik cache to ext, so even though it says you have only gotten 130 mb, it will fill up very slowly. I myself have around 100+ apps installed including google earth and some games, and i have no problem..
edit: and no you cant move apps to ext. The app2sd in froyo is moving them to a special folder on the fat32 partition, while the oldstyle a2sd+ have the /data/app and /data/dalvik symlinked to the ext-partition, so apps will always be installed to ext using this method.

ok so i took leedroid.
and posted this in his thread:
hi all,
i got the apps2sd version.
and i got ext3 876MB.
But at the first page it says: lots of free internal memory! on the apps2sd version.
but i only got 133 mb internal mb free.
So i dont think thats much?
cause my apps cant move to sd.
some can but not all games.
so my space is limited and i really need much internal memory!!!
please someone help me!
Greetings,
Nick
EDIT: and how can i check if my apps and dalvik cache are thruly on my sdext?

OMG!
Please read my post over again.....
a2sd works by symlinking some folders to your sd-ext partition. This will NOT mean that your system will measure plenty of space. Just that those 2-3 folders will not take up space on the /data partition, so installing apps only leaves a little bit of data and thus only decreases the free space a tiny bit. 2 see this better try installing "quick system info" which will let you see how much of the sd-ext partition is used. Then go install a lot of apps and see, if this fills your phone. It should not(only a2sd storage in quick system info should be filling up).
and to check, if they are there, install an app like root explorer and check /system/sd which should show the folders present on the sd-ext partition("app","app-private" and "dalvik-cache")

Are you using a2sd+ at all or are you manually moving apps to SD via application manager?
data2ext still has not matured enough with relatively high risk of data loss atm. I have no doubt the devs are working hard on it, but it is not ready yet to go mainstream. AuraXTsense sported data2ext in 8.1., yet it has returned to good ol' a2sd. It simply is not stable enough.

A2SD HELP!

I have been having nothing but problems with A2SD I decided to partition my EXT3 to 2GB and at first installed leedroid and have since moved to OxygeN both obviously show only around 120mb when I start phone I understand this. It doesn't show A2SD so I install quick system info that says I have 1.99GB A2SD storage. OK move to the future and I have around 14 apps installed and have ran out of space on my phone. internal storage 16.05mb A2SD free 1.85GB the phone is not installing apps to the SD card. It was the same for leedroid and for OxygeN. I have nearly all my A2SD space available. I have no apps moved to SD using Froyo-A2SD. I'm pulling my hair out as my phone refuses to let me download a 700k app from market now..
I tried wiping cache too it upped my free space to 17mb.

No I read thats a bad idea as it can cause problems?
EDIT - Tried it and now I have 97mb free.. AWESOME so far no probs will update if I have any more. Also noticed though when I backed up before adding the mod it had some games/apps in the devlik cache i no longer have installed? Any way I can remove them? Like Skype etc..

A2SD was the reason for me to root...tryed arround diff ROMs...had the same prob like u...then i find my perfect ROM: Acemod007
super fast, stable, super support, and the best: a2sd works perfectly! i have an 2 gb ext4 partition and round 150 apps installed and 200 mb internal free (running CM7r2)!

yep thats why i rooted It's an annoying problem.

To find out, if a2sd+ is working, open terminal emulator and type
Code:
su
ls -l /data
In the ouput you should find this
Code:
/app -> /sd-ext/app
/app-private -> /sd-ext/app-private
/dalvik-cache -> /sd-ext/dalvik-cache
If you cannot find this, partition your sd card with gparted again (save important data before this):
1.) Create fat32 partition (primary)
2.) Create ext partition (primary)
3.) Flash e.g. oxygen rom
At last, make sure you followed the instructions in leedroid thread step by step in the correct order.

is the code i should write 1 or i ?

Neither nor. It's an "L" in lower case character.
SwiftKeyed from Oxygen with Transparent XDA App

Not sure if A2SD+ is working properly or not.

Ok, i have just finished re-installing all my apps after flashing AceSMod007-3D, the first A2SD+ ROM i have used, and i am already running out of space. I have noticed that any "phone only" apps i download seem to be placed on the internal memory whilst anything movable seems to be placed on the EXT partition and doesn't decrease internal space at all. Is this how A2SD+ is supposed to work? Is my only option to free up more space to delete some of my phone only apps?

I've just rooted and installed AceSMod007 (v33) and im also confused by what goes to SD-Ext4 vs Internal... so far it is hitting Internal, although one app does have the SEND 2 SD option but not sure if that means to the FAT32 or Ext4 partition.
so well confused so far... im holding off customising the phone until i have a better idea.

Open titanium backup, it should show u system memory, internal memory, sd-ext memory and sd card memory..If the app2sd is working u should see that sd-ext is not empty
Leave away the SEND 2 SD option..this is the android stock move to sd, not the app2sd

Its definitely sending apps that were already movable to the EXT partition, but i was under the impression that A2SD+ meant that apps that previously weren't movable would now be able to be spread over the EXT partition as well. If all it does is send the movable apps there automatically then its basically the same as stock A2SD, just without the need to move them yourself

NO, that is the stock move to sd: mean a part of the app can be moved on the sd card fat32 partition, it doesn't allow every app to be moved, and the app is partially on the sd card
The a2sd move every app u install on the ext partition, is not in ur sdcard fat32 partition..it move completely the apk on the ext partition..so the space saved is enough (u will STILL see that the app can be moved on the sd card..but u HAVE to leave it on the internal memory to make the a2sd/a2sd+ fully work)

ok .. but why does the Internal Memory indicate decrease (by megs) if it is installing on EXT. I can see my game is on SD-EXT/APP but Internal went down by 3megs.

The data saved from each app (settings, preferences) is still on the internal memory /data/data so that probably is normal if the games need to save a lot of things
Btw how much is ur free internal memory?

its now 108MB of 148MB, with only Mini Info and HyperJump Installed

Its definitely not just the data. one of the apps i install is 7.5mb and 450kb of data. it decreases the internal space by 7.95mb in total after an install, NONE of the app what so ever is going to the EXT partition, and i suspect there are several other apps doing the same thing

quick system info will show the a2sd size

if u install from the market an application, it will be downloaded on ur internal memory..that the space that u see probably
restore all ur apps, and stop looking for a mb more or less..u will have lots of space available..if this is not the case then u did something wrong.

yes.. from a fresh install of the ROM it started with around 111mb free, so yeah you are correct never will get the 148mb back.. but then the Stock Rom DID have 148mb free so that like 37mb lost from the get go.
Its all new to me this apsd+ stuff so i'll start install Apps and see how far i get, on stock i HAD to use Froyo "Send to SD" to get everything installed.
thanks.

could it be you have a few extra bits thrown in (app wise) with your rom that is taking up extra space?
afaik apps2sd+ you should leave everything on internal

ok this was a good read.
http://forum.xda-developers.com/showpost.php?p=7458565&postcount=8
it kind of implies that because there a symbolic link from NAND/Apps to sd-ext/apps, the phone thinks apps are still internal so will reduce the freespace indicated in Settings --> SD & Phone Storage

Well obviously something is wrong, as i have installed around 30 apps and i'm already out of internal memory.

[Q] SD-card partitioning / storage layout on desire

Dear XDA forum,
since a few roms i always get a "low on storage" warning, even after factory reset and flashing a new rom.
So i'd want to ask for a small summery of what storage there is inside the desire and on the sdcard and how to solve this problem
My sdcard is 16GB class 10. I didnt partition it manually (i think).
according to my desire it has effective 14.2gb.about 2gb are used and 4gb are free? that doesnt sound right.
so i guess its 2 partitions?
could anyone please tell me which mountpoint is which?
and how do i solve the low storage problem? do i need some a2sd script or do i have to more the internal storage to the sdcard?
which mountpoints do the scripts actarlly move?
i have no problem with repartitioning my sdcard. i was given to understand that u usually need a fat32 partition (for apps i guess) and an ext2/3 partition afterwards. some scripts even allow a swap partition at the end of the sdcard to be used as swap space. is that a good idea?
i know its a lot of questions :/ but i hope for some good answers :>
thanks & greetings,
soomon

my advice would be to backup your sd card and (re)partition using gparted, start from scratch because I don't know what your current configuration is, step 5 here
choose ext3/ext4 partition (max ~1.5GB) depending on rom requirements, most support ext4 and should be slightly faster. most roms don't need swap partition.
in simple terms, your space will get taken up by apps (apks), dalvik cache, app cache and app data. most custom roms will automatically move apks to your sd-ext partition. there are various different scripts which move the other bits around. generally it is better to keep app data on internal (/data partition)
regardless of which rom you choose, use an app like 'diskusage' to browse all your partitions, so you can work out where and how all your space is being use.
to maximise space you also need to be s-off and correct hboot for the rom (again should be stated within each rom thread, or search within it)

ok so the first partition on the sdcard will become my sd-ext which will replace the /data partition on the internal storage.
I guess is hould try data2sd then?
with a class 10 it should not get that slow and i get loads of space on that partition.
thanks for your help.

also use links2d,very usefull.....

hi again,
as i see in a terminal emulator by typing "df -h"
my data is 150mb and has 15mb left, so i guess i better moe the whole partition to the sdcard as i'd have to move all the apps to the sdcard anyway sooner or later.
my /system has only 5mb of 250mb left. is that a problem?

depends entirely what rom you're running if any, and what scripts it uses. basically you should be able to find some way to install many apps without running out of space (one of the main reasons for rooting in the first place ).
with your current setup, you could try something like link2sd to just move apps and dalvik to sd, see if you have enough space that way. you shouldnt have to manually 'move to sd', keeping them on 'internal' tricks them to sd-ext. (you can use something like 'diskusage' to check they're actually on the sd-ext)
the system partition is meant to be mostly full. free space on /system is wasted space.
you're still on stock hboot, which is why your data partition is so small.
if you install another rom, many of them have a smaller system size, so if you're s-off you can flash a different hboot to repartition your internal memory layout: your system size will reduce to roughly match your rom, and the saved space is converted into extra data space, see alpharev.nl for hboots.
e.g. if your rom system is 140MB, will fit nicely into cm7r2 hboot with 145MB system, and you get 287MB of data instead of 150MB. 287MB can be enough to store app data and dalvik cache if you don't have too many apps.
i refer you to these sets of guides for further reading, should explain a lot more, and better than i have...

thanks eddie,
i'm still s-on and stock hboot, but i use a custom rom: http://forum.xda-developers.com/showthread.php?t=1766550
i guess the problem is that LBE gues 4 and lookout together need over 22mb of space :/
i'll try link2sd then.
thanks!

hm.. when i try to install link2sd i get "insufficient storage available". that program is not even 1MB in size and i have 15mb of free space on the internal storage.. what can i do?
edit: i'll try to install it at home with an adb tool. maybe i have more luck with that.

follow instructions for a2sd with that rom (scroll down). this will move apps and dalvik to sd-ext automatically. or follow/search the thread for other methods, it's regularly discussed...
[not used link2sd, it should in theory do the same thing, but my advice would be to stick with the instructions as that's the recommended way if you really need/want to install link2sd...uninstall something else to make more space ]

ofc removing apps might help (althrough i only installed 2 or 3). but 15mb should be enough to install a 800kb software
gonna try to install some apps later after running a2sd.
thanks a lot man didnt see that information.

easy step by step for clearing phone memory

I've read on here that people are able to install lots of apps without clogging their memory on their phone, placing all their info on their sd cards. can someone help me do that? I've already have app2card and other apps to clear up memory but things still start to take up the phone memory.
I've done the search and can't figure this one out. i'm using the atomic rom and I believe my phone is rooted. thank you.

Well, even if apps is moved to sd, their odex files will still occupy space in dalvik-cache. If you have many apps, internal space will surely be low.
I'm using DiskUsage app to see what is taking space in internal memory.
Here is some hints from me that can help you with internal memory problems:
-clear your apps cashe and data from time to time (obviously, you can do that for not so important apps, but not for games, because you will loose your progress)
-Most GB roms are not big in term of size, so there are lot of space left in /system (sometimes even more then 100MB). You can install some of your apps to system (move them from /data/app to /system/app).
-Reodex your rom. You'll get 30MB+ if you reodex just framework folder, even more if you reodex all system apps. (so all odex files will be in system partition, not in dalvik-cache (data partition)
-Finaly, you can unlock your bootloader and flash custom kernels (lupus or turbo kernel) that can increase you data partition to 610MB

thanks! i'm really happy with my atomic 7 gb rom so I don't think I will flash a new one (at the moment). I have abou 120mb left in my internal memory....is that pretty good? will reodexing your rom slow down the system?
appreciate the feedback.

120MB is OK. Actually, it's all ok untill first thing you want to install fail due low space. Then you can think of things posted above.
No, reodexing rom won't slow your phone.

I think your referring to Link2sd. I have about 300 games/apps installed and still have loads of space. Look up link2sd in the market and follow the instructions. You need to format your sdcard and use minitool partition to make am ext2 or ext3 or ext4. I use ext2 foe the partition. Make it around 1-2gb in size. I made mine 3gb. The rest is fat32 format for your sdcard. When you install links it will ask what ext type it is. 2,3,4 etc. Select the format and it will install the script them reboot from that point all installed apps will be linked to that partition. Freeing up a lot of space. Like instead of a few megabytes of storage its more like a couple kilobytes as its just a file telling your phone where to look foe the application or game on your ext partition.

First, make a backup of your sd card to PC.
Minitool is program for PC. Tutorial how to use it (with download links) is at http://forum.xda-developers.com/wiki/SD_card_partitioning

so do I partition (say ext2) first? and make it 3g. then I format the rest of the space fat32?
sorry if this is so basic.
