I'd be interested in a tutorial for this as well.
Thanks

Most opperating systems have a built in manager for it, including windows. Look on YouTube, that's how I did mine.
Or use clockworkmod.

On windows you can create partitions but swap belongs to linux so unless you use a ubuntu live CD or a machine with ubuntu...

A ext2 partitions is the same on all operating system
Clockworkmod will also partition you sdcard

So i just create an ext2 partition on my sd? Then what's next?

Back ur memory card up first. Depending what size memory card you have depends on the size of the partition
The most you will need is 2gb, I would only us 500mb.(2gb sdcard)
You need to have a fat32 partition for your normal data and the ext2 for the swap file. Then just put it back in you phone.
BTW I lost my last memory card trying to unpartition it. So if you only want 1 extra paelrtition use clockworkmod.

I think you tick a box. Download swapper2 from the market place, one of them has more options than the other

SwiftDroid ASIS and Swap?

Hi there,
I never dealt with creating swap partition. I'm using latest SwiftDroid now and like to know if it uses swap automatically. If not, would it be advisable to create one? How do I have to do this? Which size should it have and does SwoftDroid ASIS recognise it rigth?
I googled a lot and search in the forum, but didn't find helpful information.
Thanks

using swap isn't the best idea as it kills ur sd card faster.
also a lot of people use about 200mb swap partition to about 300mb swap
partition..
u could get the app from the market ( swapper2 for root users )
or read this thread!!
http://forum.xda-developers.com/showthread.php?t=1317362

Mur4ik recommends swap 256MB for previous versions of SwiftDroid, so I think that is also applies to ASIS. ASIS can use swap automatically (no need to use swapper app) if you create swap partition as third on sdcard (second should be ext - in newest recovery you can create 2MB ext3 partition).

Okay, now slowly. I flashed my phone with Mur4ik's KDZ Method before installed SwiftDroid. So there should be 150MB for system,64MB for cache and 234MB free internal storage. Are the 64MB memory for swap? So that SwiftDroid always uses swap but with internal memory?
Now I don't understand what you say about second and third partition and what exactly Mur4ik suggest for his ROM. They are both an SD, aren't they? I use a 16GB class 4 SD card. So what should I do to get best performance with ASIS?

150MB for system,64MB for cache and 234MB free internal storage <- it's internal storage of your phone, system is just system, cache is for files downloaded from internet, internal storage is for installing your applications.
On sdcard you should have primary partition (fat32), ext3 and swap (linux swap type) partition. The third will be automatically used. See thread mentioned above or copy everything from your sdcard to you computer, reboot phone into recovery and creat ext partition and swap partition (in that order) through recovery. Then reboot phone and copy data back from computer to phone's sdcard.

Ok, i managed to create 256MB swap partition.
So what do you say is the best swappiness value? I read that 60 seems to be to high?
PS: How can I see if swap works?

I leave mine at 60 to see If it works type free in a terminal on the phone

Ok it works. Terminal shows me that the phone uses swap. But I also recognised it by playing some games, which worked laggy before and now run very smooth.
About swappiness: I read that 30 seems to be the best for our phone?

ASIS set swappiness to higher value (I believe 60) - I've changed it to 30 in previous versions but now I just left it as it it. I don't see any difference.

Yay! no more third person software :3, native swap.
Thanks :3

if you mean by choosing settings - app settings - manage apps and choosing to move an app to sd card, thats not how ext works, what that does is takes it FROM the ext partition and puts it in the FAT partition.
The apps should all be set to use internal memory, and the system will put them in the ext partition without you doing anything.

I advise installing Link2SD, I had a similar problem and this program fixed it for me.
Just mount the storage space and then you will be able to create link (that means moving the app to ext partition).
Hope it helps.

i haven't used miui so i can only comment on cm7 roms with a2sd+.
Did you create teh ext yourself? because i have read that if the ext and fat are not in the correct order (i cant remember which should be first, which second), if they arent the correct way around the system wont see the ext.
Have you used an android browser to look at the contents of teh ext? is it REALLY empty?

one other thing is that the internal memory will go down when you instal something, but REALLY the app has gone to EXT, and the internal free memory will go back up after a reboot. Its a free memory display bug. The system just assumes it has used the space up without checking it until after a reboot.
So you install a 20mb app, the internal memory drops 20mb, but after a reboot has gone back up 20mb.
Just a thought.

If you partition your sd card in GPartEd, your FAT32 partition should be first (on the left) followed by your ext3 partition.
Or you could use CWM or even ROM Manager (I think, not 100% sure about ROM Manager) to partition your card.
Try flashing this in CWM Recovery:
http://forum.xda-developers.com/attachment.php?attachmentid=749299&d=1318560772
And then when you reboot, go into your terminal emulator app and type:
su (press enter)
a2sd reinstall (press enter)
It should then say a bunch of stuff, and then your phone will reboot and take a long time to boot back up, because it is moving all your apps to your ext3 partition.
I would really recommend using gparted to partition your card, it's very reliable, gives you the most control over what you're doing, and you can download an iso to make a bootable cd of it if you don't use Linux. Google 'GParted Live CD'. (But why wouldn't you use Linux???)
Do a CWM NanDroid backup before you do any of this, in case your rom is not A2SD compatible and it screws something up. Then you'll be able to revert back to your present state. I can't stress the CWM backup enough, especially because I'm not sure if MIUI roms are A2SD compatible or not. Either way, I think it's worth a shot.
Back your sd card up to your computer before partitioning it, as it will wipe everything from it.

So,I did this: Wiped all and installed rom again,app2sd gui now working (apps are on sd) but i still have a little space left. Only installed apps I really need and i have less then 30% available.
I even linked all apps I could with link2sd app.
I dont know,I will try to reboot now and see if something happened.

You only have a little space left on internal memory or in your ext partition?
You have a EURO HD2, so you're not gonna have a bunch of internal memory no matter what. Your ext won't show up in Settings/Storage/SD Card.
In order to see how much ext space you have left, look in the A2SD GUI app.
How much space is left in each of those? (ext and internal)
If you are using the A2SD that I linked in my previous post, you won't have to use the link2sd app.
It creates the symlinks to the sd ext partition on its own.
How big of an ext partition did you put on your sd card?

what system partition size have you flashed?
what size partition does the rom (you still havent linked to teh rom you flashed so we cant look ourselves) say you need?
because that doesn't count towards internal space, so for example if your rom requires a 150 meg system partition, and you flash a 250meg system partition, you will lose the extra 100mb. you wont be able to use it for apps or data, it will be dead space.

hmm its a 90 meg download, so 150 system should be ample. do you have masses of text messages stored? (i know some people have thousands, never delete any, , , weird) or tens of hundreds of contacts that could be filling up the data partition? (your systems 'internal storage' figure is based only on the data partition)

Problem regarding Swap

I'm using Lewa OS v4,
Initially there is a Swapper working, with a swap file on System partition (not more than 32 MB).
But i want to make it some large, i tried Ext 4 partition on SD Card .
I go to the swapper setting and change the mode to sdcard partition ,
It says ' swap open failed '.
I reboot, swapping becomes normal but also that partition mounts at /data/app
That is phone memory is replaced by this partition and the apps which i install in phone memory it install on this partition.
And when i check the storage in " Managing Application " tab in setting it shows the real phone memory with apps installed on ext4 sdcard partition.
Its too messy
And due to this i am having trouble using ext4 sdcard partition swap.
Is this is a problem with GB Roms or only with Lewa rom v4

Friend,
Use this menthod for swap in lewa os rom v4:
1.Backup ur currently data in CWM(skip this if u want a fresh install)
2.Backup all ur data in SD(place it somewhare in ur pc)
3.Reboot in CWM>Advance>Partition the SD Card>the ext3>512m>32m
4.Press Enter key.wait till its done.
5.Now u have 512mb EXT partition with 32mb SWAP partition & ur SD is REFORMAT.
6.Copy back all ur data
7.Reboot again in CWM & restore or install fresh rom
8.Go to swap in phone(u know where)and apply SD swap.
DONE
why just dont ask in my thread.....

What it means that 512MB EXT4 partition and 32MB Swap partition?
Actually I don't want partition for App to SD.
And if swap is 32MB then swap file in system partition is more feasible. As i know that phone memory is more faster than sdcard in any case. (Might be I'm wrong)
But in my case it is true, I have class 2 sdcard.

Depending on the apps you often use & how often those apps swap-out RAM, you might actually experience performance lag. Asides (I insist!), beating your card to death.

[Q] Internal Memory Low Space on ICS 2.4.27-HWA

I have installed MIUI.us-Leo-2.4.27-HWA.ZIP in to my HTC HD2. Everything is working fine except Camera and phones internal memory is very low, only 25MB resulting cannot update any existing applications.
My phones total internal memory memory is 151MB and available is only 25MB.
SD card total space is 15GB and available is 9GB which is fine.
Total downloaded applications are 26 only, so it is not that I have too many application downloaded.
I moved most of the downloaded and other applications to SD card by using titanium backup. Few could not be moved for unknown reason as it does not give me option to move.
Can anyone please help me to increase my internal memory to at least at 70 or 60MB please.
Would appreciate your help.

i have used a few MIUI roms & did not have that problem
what is the data.img that you used?
are you using NAND rom? in that case what was the size of the partition you used, did you follow the recommended size?

Yes, it is NAND ROM. The recommended partition was above 200mb and I used 250mb, so it was okay.
All I need to increase my internal space at least to 60 or 70mb so that application update can be done.

The ROM suggested 200, but you installed 250. You just lost 50 worth o internal storage.
You'll need to install an A2SD script, in order to be able to use your sd card as an internal storage. (of course, after making an ext2 partition )

Marvlesz, I looked for 200MB partition but could not find anywhere. That's why I installed 250MB. There are only 3 options they gave which is 150MB, 250MB & 400MB. Please suggest me in details how I would be able to do ext2 or ext4 using A2SD
