I will apologize if this has been asked before. But I have been search for while and still have no clue.
The situation is: I normally run android with haret on sdcard without partition. (Thanks to all the developers). Every build is very fast except the most recent mssmison eclair (the new way). So, I tried to run the mssmison eclare on sdcard with partitions. It turns out to be even slower. I then tried most of the other releases which were fast without partition. All of them became very slow on partitions.
I guess it is possibly because I have a sd card without any "class x" label, (maybe class 2). But anyway, shouldn't android be faster with partitions than w/o?
or is there something related to permission fix?
Here is my settings:
Htc vogue
3 partitions: fat32+ext2(system)+ext2(data), I also tried fat32+ext2(system)+ext2(data)+swap, all very slow
Thanks
make sure you are choosing the right options in the installer. if you have system.img and data.img in your /andboot folder, then you are not running off the ext2 partitions and choosing the wrong default install location options.

After install , I have no sytem or data in my /andboot or /android folder. The system is renamed and moved to a backup folder by the installer. with the new way, I can choose where to put the system and data, "system on sdcard" and "data on sdcard", which are default, are selected.
Yes I also noticed that Eclair wasn't running fast even though I was using two Ext2 partitions. I didn't notice any speed difference between having the files stored directly in the android folder as opposed to Ext2.
definitely thought I noted a speed increase running on ext2 instead of regular sd card.
i really wana know which partition is better ext 2 3 or 4? n also if u can move songs etc to the partitioned space??
what exactly is app2sd??
I am using RAFDROID ROM on a TMOUS HD2
in the instructions he said that if I am using a euro HD2 with 512 rom I should partition my sd card
so I did not do that and flashed the rom on my NAND
then when I started using apps I noticed that after two weeks usage I have only 50 MB left!!!!
so I want to activate app2sd and move my apps to the sd card..
so please I need some help from the experienced users on this great forum that can advise me about what exactly is this and how to activate and use it
thanks in advance!!
Apps2sd moves your apps to the sdcard, usually to an ext 3/4 partition. I don't know about the ROM you're using, but on the one I use (mdj's Cyanogen 2.6), you can move apps to external storage like this: settings --> applications --> manage applications. Then select an app and there is an option to move to sdcard.
@freeincolorado, the method you described is not A2SD+, that method is called move2sd.
A2SD+ puts the dalvik cache as well as the applications in a EXT2/3/4 partition, usually called the sd-ext partition. This method will still show you that the application is in the ROM. However, the sd-ext is used instead, depending on the chief implementing A2SD+ in their ROM, the remaining ROM space is suppose to report the partition "sd-ext" free space, however, certain ROMs are not properly done in my view, and will report the userdata partition free space instead. Such as MDJ's Cyanomodgen 7+ Gingerbread.
How to use A2SD+
Usually, they require you to partition your SD Card into 2 primary partition. The first partition is FAT32 where you store all your extras, such as music, ebook, etc (Like how your SD card is presently used). The 2nd partition is EXT2/3/4 depending on your preference, most people do not use EXT2 anymore as it does not support Journaling, since data can be easily corrupted with a battery pull. EXT3 and EXT4 contains journaling feature, so when battery is pulled, data corruption is minimal.
NOT ALL ROMS SUPPORT EXT4. This is a kernel thing, so if the rom uses a kernel that does not use EXT4, then it will not read the partition.
A2SD+ has a nice feature as well, when you switch ROM, you do not need to re-install all the applications, since all applications are placed in the sd-ext folder, including the dalvik cache. However, this also includes the system default applications which might not be compatible with another rom build.
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.

Thank you, that was sooooo relevant!
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.

I can't anderstand what sd the idea behind program S2E, it seems its purpose is to move apps to SD but when used it this way then all newly installed Widgets disappeared What's more even without launching S2E in Settings thare are options to move individual apps to SD (not for all in fact)
it isn't talking about the normal fat partition on the sd card, you must have an EXT partition created before using the app.
What it does, is take the ext partition on the sd card and makes the system think that it is internal memory, thus giving you more 'internal' memory for apps and data and such like.
This isn't the same as choosing 'move to sd ' in the settings - apps options, as this moves the app to the FAT (windows) partition of the sd card. Some apps wont work when 'moved to sd', however they WILL work from the ext partition, because android thinks its internal.
So, if you haven't already got an ext partition, back up the contents of your current sd card (it will get wiped) then reboot into cwm, choose 'advanced - partition sd card' and choose a partition size. (512 or 1024 is usually plenty) then restart android and try the app again.
Any apps that you have already 'moved to sd', go move them back to internal, and the system should automatically move them from the FAT partition to the EXT partition.
Tahnk you for your explanation. Also I must apologize I confused the names of the programs - in fact its S2E rather than A2S (the previous post have written from memory). However probabely this s2e serves the same purpose, as it has such relevant commands:
Applications - Location: /data/app
Private apps - Location: /data/app-private
...
and so on, until:
Dalvik cache - Moving from /data to /sd-ext
So, I've chosen the first option and got displayed:
Application
Moving from /data to /sd-ext
Reboot is required!
and rebooted the phone, but the result was disappointing - several apps dissappeared including all Widgets!
Of course I've had ext3 partition previously set.
What was wrong?
Other question please: exactly WHAT is worth moving to SD Ext partition, Dalvik cache too?
yea they do the same/similar things - namely move parts of the system to the ext partition, and create symbolic links so that the system doesnt notice they've moved.
You seem to be moving your entire data folder to the ext, which i believe has an impact on boot performance, since the data partition wont be mounted straight away, and android needs it during boot.
I don't know a great deal about the various app2sd scripts, but the ones i've used normally only move the /data/app/ (your user installed apps folder) and the dalvik cache to the sd-ext partition.

So won't it exert excessive load on SD card which could lead to some sort of instability or other issues?

better than exerting load on the nand and increasing the chances of bad blocks, right?

theoretically YES but then does it also apply for the whole Android ROM itself (please compare the neighbouring discussion "is NAND Android better than SD and why?")

no thanks, i have far more interesting things to do. i couldn't care less if there's excess load, though i'm pretty sure there isn't, since i've been running an ext partition for several months and no problems.
Have you understood me well? I've asked about the problem probably NAND ROMs themselves wear NAND memory too so would it be safer (for the device) to use SD ROMs (which write only on SD memory all the time)? How do you think, could it be the case?
i think if it were of any real benefit, people would be talking about it, but no one does. I guess its down to you, if YOU think it will help, then do it. If you don't, don't!
I guess battery drain would be teh real deal maker/breaker. I havent used sd android, but i believe it to be (in general terms) a little less stable, more prone to slowdowns, and harder on teh battery. But thats all anecdotal evidence, as i said, ive never booted sd android.
(edit - i must say, in humour, not meaning offence, that between this thread and your other thread, you sound like a guy who just bought a sports car and wants to cycle to work to save wear and tear on teh car )
i have Nexus HD2 CM9 on my phone and i have only 151 MB available memory. Is there a way i could increase the internal memory ?
And y dont i have "Preferred Storage" option on the applications settings ?
Backup the contents of your SD, then create an EXT partition on the SD card, then use one of the many a2sd, app2sd, d2s (there are many variants) to make the system believe the ext partition is internal memory.
Don't say "can you help me?",,, there are loads of threads dealing with this,,, you may even find your rom supports this without you needing to do anything except create the ext.

Hi!
Its right, there are several threads talking about changing partition sizes.
i suggest using this tool:
http://forum.xda-developers.com/showthread.php?t=1090783
If you want to keep you data partition as clean as possible the first app you should install is Link2SD and set it up to link installed files automatically.
@op the partitions that the above linked post talks about is not the same as the ext partition I mentioned. If you do use the nand toolkit at all, be aware you will need to reinstall your OS.
