have you partitioned your sd card correctly?
http://forum.xda-developers.com/wiki/index.php?title=SD_card_partitioning
check your roms original thread to see what sort of partition you need.

which ROM do you have... and was A2SD+ part of the ROM, or sth you added?
I think I read somewhere that some A2SD+ implementations don't move the Dalvik cache over to SD. The (easiest) method to add dalvik to SD likely depends on the A2SD implementation.

Use S2E , download it from Market.
thanks.

what is better for a2SD, ony ext3 or ext3 and swap???

The a2sd script in Cool's AceS v1 does move the dalvik cache to the sd card, so most likely the card isn't formatted correctly. I suggest you use gparted or a similar tool to format your card like this: first the FAT partition, then the ext 2/3 one (note that some roms require you to have an ext 4 partition, but this is not the case of AceS; anyway, make sure you read the thread thoroughly before flashing). Also, make sure the ext partition is no larger than 2048 MB (i.e. 2 GB), since you might experience market problems. Swap is not used by most roms you'll want to flash these days, so don't worry about it too much, unless the thread mentions so.
Just to mention, S2E is only for cyanogen mod, as it's stated in the app's description, so don't use it with other roms (which have other a2sd scripts). Also, before formatting, don't forget to backup your data
Good luck!

Hello guys!
i'm new here just want to say that it's probably the best site for modding.
I have a desire with Ginger sense ROM.

Link2sd is free on the market. Uses ext and fat partitions. I have link2sd on my Kyocera Zio m6000 which only has a total of 180mb in data and I have 137mb free. Link2sd allows you to create a symbolic link for app data dalvik-cache and lib files of the app you want to move to SD. Plus with the symbolic links you get to keep your Widgets.

Dalvik Cache will take up space on "Internal storage" by default on some A2SD + ROMs, but it can be moved
You can move this by running "terminal emulator" from the market and typing:
Code:
su
a2sd cachesd
or with adb:
Code:
adb shell
a2sd cachesd

please note that davebugyi's suggestion only works if you're using the Darktremor a2sd script

[Q] noob question - created ext4 partition on SD, but how to use it?

Hi,
I've created an ext4 partition on my SD with the intention of using it to store apps on
I used the gparted method described in http://forum.xda-developers.com/showthread.php?t=1016084
Now I've flashed a couple of ROM's (Oxygen, Redux and CM7) but have no idea how I can put apps on it
Additional question:
1) if you do a data, cache/dalvik wipe will the apps on the ext4 partition also be deleted or will they remain on it so you can reuse them in another ROM
2) I've rooted and s-offed my stock rom, can I use the partition I've created here as well? and if so, how?
thx
B

on all 3 roms youve mentioned you tried, app2sd is automstically setup on rom install. so you are already using app2sd.
1. yes if you wipe dsata, it wipes your apps on ext 4 partition
2. and yes, your aready using your partition once your using a app2sd rom. specific roms allow you to push your dalvik cache to your partition but it is not reccommended as it can slow donw your phone.

hi,
thx for the feedback, can I install app2sd on my stock froyo rom somehow?
I'm rooted and s-offed
Thx

extra test: I've installed Leedroid with app2sd
when I install an app from the market my internal memory decreases and I cannot move it to SD card
I've created a 500mb partition, should this be visible as "internal memory"?
cheers
B

Some apps still need some space from the NAND internal memory.

Nope. But if you download "Quick system info" from the market, you will see where it's written A2SD your external partition and its used space.

If you are like me and want to install lots of apps app2sd is not good enough sorry I was on Leedroid superb ROM but I soon ran out of install memory because even if you move app2sd say you have 20mb app and move it to SD it will move like 16mb to SD and 4mb will still be on phone.
Best way is Data2SD I use startburst and have 2gb ext4 and my phone thinks it has 2gb internal memory
Make sure you backup and have a SD card class 4 and above some say class 2 fine I dont think so.

[Q] what does a2sd+ actually do?

i have installed miui a2sd+ edition... i have created a 512mb ext partition... i still have low storage issue... but i still have a lot of space available on my 512mb partition... (only 100mb is used up) and internal storage i have only 20mb left... why aren't the apps stored fully on the ext partition?

u have to flash the rom after u create ext3 partition

yup already flashed the rom.... still it used 100mb out of 512mb of ext partition but i have only 20mb internal space available.. why aren't all internal memory moved to ext partition?

There is plenty of information about what a2sd+ is and does. Try searching!
If you need more space search fire data2sd.

ok thx... so basically what i am reading is that a2sd+ is mostly like the move to sdcard feature of froyo and gingerbread...? 512nb is way too much if i understand correctly

okie i installed data2ext version of miui!! it's great!! i now have a true 1gb internal storage!!!

[Q] RcMix/insertcoin a2sd vs cm7

hi, i was just wondering if someone can tell me the benefit of cm7 over a2sd please, im S-OFF so no problems changing, but just wanted to know the differences. and also which is better, insertcoin or rcmix??
cheers.

I think I read a possible speed increase with cm7
Different system partition sizes..
Sent from my HTC Desire using XDA Premium App

ok so what the big deal about the system partition being bigger.. what does that mean in real world case?

In the a2sd apps and dalvik are on sd because there is no much space
In cm7, apps are on SD ,but dalvik cache is on internal.
Dalvik is the virtual machine that runs on android to provide that java environment(behind that is Linux). Also internal memory is faster on read/write even from a class 10 SD card. That way we take advantage of the internals speed , which makes the Rom a lot faster. Also since the ext partition is used only for apps, there is more space available for more apps than a2sd

Cm7 does not officially support a2sd. Even if you have an ext partition on sd card, you also have to run a special script or program(strange issues occur here sometimes). This is why it's recommened to have cm7 hboot when you run cm7 rom, because with cm7 hboot you do not need a2sd because of the big /data partition.
Furthermore, as far as i know the difference between a2sd and a2sd+ is the following:
a2sd: only apps will be moved to sd card
a2sd+: apps and cache will be moved to sd card.

So. if we're in cm7, it would defeat the purpose if we use mcr scripts to move dalvik cache to sd? It's just that I noticed an increase in internal storage space. Is that not a good thing?

that is true indeed, but insertcoin gb cm7 used a2sd while the stock hboot uses a2sd+. I was talking specifically for these roms , not for cm7, but the cm7 hboot gingersense roms

[Q] a2sd confusion

I wiped my SD card, partitioned it with a 512MB ext3 (via Amon RA), reflashed cyanogen 7.2 ...
I thought CM had 'built in' a2sd -> ext, but even after moving apps to SD, my ext partition is still totally empty!
It's actually moving my apps to .android_secure on the FAT partition!
And installing apps is filling up my internal memory ...
Do I need to enable ext usage in CM?
Help!

im not sure about cm, but i know in other roms iv used you had to use terminal and type the following:
su[ENTER]
a2sd reinstall[ENTER]
if your not sure you can always flash dt a2sd and do the above and go from there. Also... why only 512mb ext3 partition? i got a 32gb card and used a 3gb ext3 partition. i wanted to make sure i NEVER ran out of space for apps. I dont remember if i saw it there, did you upgrade your ext2 to an ext3 partition via AMON-RA? in case you need dt a2sd here is the link.
http://forum.xda-developers.com/showthread.php?t=715938

I see, thanks, didn't know had to 'activate' it.
But in the meantime, I installed S2E (from Market) – now my ext is filling up –*but my internal is still down to 83MB!

I think I figured it out -- it's my app data (/data/data 130MB) and dalvik cache (/data/dalvik-cache 107MB) that are still internal.
