hi there
hope u people are fine...
my question is what is the max size we can keep on ext. partition on sd card
i have 8 gb card
currently i have 512 mb on my ext partition but still whenever i install more apps it give error memory is very less and phone works very slow it is always aroung 54- 72 mb only to before starting any app or game i have click on task killer
is there any solution to this...
or any rom which can solve this isssue currently running 1.5 froydvillain
because of this issue i have started hating my hero
please let me know any solution to this
Simple solution back up ur EXT - partition & format it. Otherwise Download Quick system info App from the market & Check your App2sd is working correctly or not ..
thanks for your reply
what should be the size of ext3 partion if i have 8 gb memory card ???
512 mb or more
i think it doesn't matter you can make 512 or 1024 Mb also .. but just too not sure
the size of the ext-partition should not be the problem...
format your sdcard (back it up first)
and be sure to create an ext2 partition just to be on the safe side
some kernels do not support ext3+
(not sure if ninpo's kernel does)

Should support it, but use EXT2 to save the life of your SD card
Your dalvik cache is filling up your on board memory.
I have a TMOUS HD2 1024 from the US go live release (red reset button). I have been using various Android builds for a few weeks now and love the MDJ's CyanogenMod 7 v2.2 (11 JAN). My question is this:
If I use one of the builds made specifically for the 1024 ROM will I see better response times? I know they are compatable since I am already using a 512 but more importantly would there be any benefit using a ROM designed for the 1024?
If there is a differnece is there a way to modify this build so it takes advantage of the full 1024 ROM? I have seen discussion related to changing the size of some spicific files that modify storage sizes but am very novice to phone edits and quite cautious. Any help would be welcomed and if this has already been discussed a simple link would be most appriciated.
With 1024MB ROM, there are no advantages in terms of speed performance.
However, you do get space advantages.
If you flash a 350MB ROM, 350MB is being used by the system partition, a small amount is used by the boot partition and cache, then the rest are all userdata partition, which gives you around 500MB free space to install apps and store user data. (SMS, etc)
People with 512MB ROM, 350MB is being used by system partition, minus boot, cache, you have like around 50MB to 100MB left which isn't much for apps and user data. Which is why they need to use A2SD+ or DATA2EXT or similar methods of increasing userdata storage.
Try using Clockwork Recovery. You will have ALOT of free space. Even if you don't do A2SD+ partition, since MDJ's Gingerbread Cyanogen uses less than 150MB for system partition.

Thanks so much best info so far.
Hi, I am using MIUI with Android version 2.3.7. Everything is allright, but I only have 217 mb of internal memory in total. The MIUI ROM and other apss take up about 180 mb and although I have moved some apps to sd I now only have 40 mb available. It should have 512 mb internal memory. Why can't I see and use all of it? Is it possible that I didn't delete windows mobile or one of the other android roms I have used so far, though I am sure I have tried "clean install" a few times?
Dalvik cache & app data take up a lot of space too, you could move these to th SD ext partition to free up more internal memory. You will need a2sd installed I think to enable this.
Peace

the 'available internal memory' figure only counts the data partition size.
so (for example) if your rom requires a 200 meg system partition, you would show..
512 minus 200 minus whatever cache size you flashed minus the boot and recovery partitions (lets guess 50 meg) so your available internal memory on a completely fresh install, no data or apps, would still only show a max of 262meg available.
Also, if you flash a system partition bigger than required, you dont get the extra space to use. So flash a 180meg rom onto a 250 meg system partition, and you lose 70meg, the system wont use it for anything.

Thank you so much. My ROM itself is about 100 mb. How much data partition size should I actually spare for such a rom? Also could you please direct me to the post that tells me how to arrange the data partition size and do the rest of flashing my rom again? I would really like to have more available internal memory. Also I would be happy if you told me what ext 3 or ext 4, whatever it is called, is and if it has anything to do with internal memory.
If the rom is 100mb then you need a partion of at most 110 so if your using clk or magdlr..after you have wiped nand...partition it to 110 if possible or use 105 even cos you don't wanna be giving up wanted space..
I'have flashed a lot of roms already but i'am still wondering how the memory works.
My favorites are the roms with Sense from DungPHP.
Now i'am running Coredroid that gives a load of manual options but also crashed unexpectedly.
Why this questions:
Every rom crashes somewhile. To understand how the memory works can help to find the rootcause. That can be application related, or configuration for the partitions, core etc.. Now only the developers know this (should know )
My Phone:
The Phone HD2 HTC LEO (EU) has 512 Mb memory
EXT4 partition of 2 gb
SWAP 256 mb
SD card of 16 Gb, 4mb speed
[*]What kind of memory's are there?
[*]and where are they used for?
To install the Rom we have to give the correct configuration like:
misc ya 1M
recovery rrecov|ro|nospr filesize recovery-raw.img
boot yboot|ro 5M
system ya 175M
cache ya 5M
userdata ya|asize|hr allsize
So when i have 512mb - 1 - 5 - 175 - 5 = 313 mb left over
[*]Where is the left 313 mb used for?
[*]What is installed on the EXT4 partition?
[*]How much do you need to keep for good performance?
This are a lot of questions and i hope someone can help me to figure it out so we have a usefull tutorial page left over.
[*]Where is the left 313 mb used for?
[*]What is installed on the EXT4 partition?
[*]How much do you need to keep for good performance?

1 - 313 would be the userdata partition (allsize). This is the only nand partition which counts towards total internal storage.
2 - depends on the rom, some put user installed apps there, some put apps and dalvik cache, some put the whole data partition there.
3 - doesn't matter, you are talking about rom, not ram,, free rom has no effect on performance.( well, perhaps if every tiny scrap of space is full, but you sound like you meant ram)
You are right RAM has effect on performance.
The problem for me is that i understand lots of fragments of the theory but it is not complete.
Like today i have installed a backup, and later a full installation of a rom on my phone. And this rom was working fine in the past and now the battery lacks and streaming video is not working. Why??
I did a cleanup to factory, and cache and dalvic cache, but it looks like something stayes and is not formatted.
Back to runny. Video works fine now. But the sense is stopping very often due to lack of memory.
Is there a way to improve this?
I removed almost all widgets from main screen but after opening an application it is stooped and needs to be reloaded.

Flash marc 0.1.9 kernel and then add a zram (100mb) script to increase virtual memory size.
I already improved the phone by changing the config from 5/170/5 to 10/180/10. Especially cash was the problem what I think. Till now it worked fine.

Hello everyone! Yesterday, I tried to flash the new ICS CM9 and I did it. It is laggy and I can t install GAPPS.Then i saw that my system partition is 160 mb instead of 215 (recommended).
So, how can I change my system partition from 160 to 215 ? (I tried some TPT Gen2 tutorials, but nothing).
Thanks!

ok first go to market and download tpt helper.
then choose make your own tpt fill chache as 20 mb system(dont make it less it is recommended to use 20 mb on ics) as 210 mb(or as per ur choice but not less) and rest will be system.then click ok.
it will download the tpt and edit it accordingly.then check it it should have from the app there should be 10/12 matches.
then reboot.
press menu+power+vol up then green text fill flash and tpt will start on its own.
if there is a error at 99% down worry wait and then it will be success.
u r done.
just remember to have a rom on your sd.
there will be other options like choosing splash screen, recovery etc choose accordingly in the app.
u can even use your nandroids.
remember to delete image folder from sd after flash to prevent flashes by mistakes.
u r done enjoy
thanks saaransh9 i also want this info, voted up
sorry, but my number of matches is 1/1 .It is all right?

When u set your partitions does it says finished if yes then it should be ok.
Or just TPT with the 220mb system partition version, reinstall your rom and you're done

yes u can do that but the stock has 20 or 30 mb oem space which is a waste instead i get 210 mb system 210 data and 20 mb cache when i made my own tpt

Hi to all, I am new at all this android stuff, so I hope you won't laught, but I have few questions.
1.Is there a way to change size of partitions without flashing new rom?
2.How big the partitions should be (System, Data, Cache) ?
According to "Blade Checker" I have European ZTE Blade 512MB, Gen2 phone, also it said that I have to use image.bin style TPTs.
Curent partitions are:
System 220MB
Data 160MB
Cache 37MB
It is running CM 7.1 stable mod and Clockwork Mod Recovery 5.0.2.0
Thanks in advance, and I am sorry if I posted at a wrong place.

1. No,you cannot.
2.Your partition size is more than enough for any new ROM's. Minimum System partition size varies accordings to different ROM's. Minimum data is according to your needs for app storage. Minimum cache is 20mb,but keep in mind you can't download anything from market/play over 20mb. So cache decides your temporary market storage.

I have only 20-25Mb left on data partition, that's what bugs me.
Was thinking maybe to increase Data prtition or maybe install 4GB class 10 sd card I have and try to make EXT partition on it, 2GB I have now seems a bit slow for that.
Would one of thos things help?
Thanks.

You better get a 4 or 8 Gig card. Class 4 should do actually.
You've tried A2SD right?

No, actually I didn't tried A2SD, I think, I am using App 2 SD, free version, but I assume that's not the same, also I think that my card has only one partition.
As I said, am new to all of this.
Sorry for bothering you and I really appreciate the help.
Thanks, again.

A2SD gives u lots of space. I have a 4 gig SD card with a 1 gig partition and I've 300 apps installed
Here's how u do it
-backup ur SD card
-boot into recovery
-select advanced
-partition SD card
-select size. recommended 1gb
-select swap size as 0. Select 32 if u use it for gaming
-reboot
-install s2e
-check all four boxes
-reboot
-start installing apps

If you changed your partition sizes, your rom and all your data would be wiped. If you made a backup before, you could restore it afterwards as long as it could fit in the new sizes (eg. if your rom took up 160MB in system just now, and you changed system to 170MB then it would fit so you could restore it, same for other partitions).
Size for the partitions depends on what rom you are wanting to install. Some like Swedish Snow can fit in 128MB system, others like the ICS ones need ~180MB or bigger.
As your current layout is big enough for any rom out now, you'd be better making an ext partition on your phone and using that. S2E from Google Play works well with CM7 and lets you move most, if not everything, on the data partition to the ext partition. Its usually best just to move apps, but it means you can have loads of space. You can choose the size of ext partition depending on how big your sdcard is and how much space you need.

2MB is the minimum for cache. You can redirect the market downloads to data/ext partition/somewhere else, so you can download any app you like. Most roms do this automatically if your cache partition is small. By making it bigger than 2MB, you are either wasting the extra space if its still small enough to be redirected, or you are restricting the size of apps you can download if its too big to be redirected.

I stated 20mb as minimum because Tilal recommended 20mb for ColdFusion and I would rather change partition sizes once than doing it repeatedly.
Sent from my ZTE Blade using XDA app
Well, I did few things.
I did what QuantumFoam suggested, partitioned my old 2GB card that was already in phone, created EXt partition of 512MB, to try if it work. I'we made backup on PC, but when I rebooted few of apps I had on sd desapeared, also all my music, pictures, wallpapers and other stuff.
Question I have now is should I copy all the things from PC back to SD and where.
Thanks all of you guys for helping me and having so much patience with me.

That's because ColdFusion didn't have the redirect script added yet. If you add that, then 2MB is fine for it as well.

I think creating the ext partition formats the whole card. If you plug your phone into your pc and turn on usb storage, you should see it appear with ~1.5GB space. You can copy all the stuff back onto there and it should work again. You might have to reinstall the apps that were moved to the sdcard, don't know if just copying them back will work.

I did that, reinstalled few apps and it works, thx.
Have one more question, if you all don't mind
I know that these questions sound stupid, but as I said, I'm new to all of this and have a strong will to learn.
Is it possible to switch this card with bigger one I have, without flashing ROM again?
If it is, I would apritiate If someone could point me to some guide, because I presume it is not easy task and I think I bothered you enought already.
If it isn't possible, can I then format new card on my PC,copy ROM on it, partition it from CM recovery and then install ROM and all of the apps?
Thx again
