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] How to get widgets to run from SD card

i got my last question solved but I read somewhere that usin darktremors script would allow me to run widgets from sd card because the system thinks they are still in the correct place.
running GV1.5 partitions fat32/ext3/linux-swap.
I installed the script after mounting /data and /system from the recovery. After that I rebooted and ran the script commands. Moved a widget to sd card and it vanished from screen just like froyo.
what am I doing wrong?
I know you need to move the dalvik-cache for this to work. but recovery can't find sd-ext.

Huh? From what i know widgets will not work if u put them in the micro sd.

Using stock froyo a2sd (apps2fat) will not allow you to run widgets. If you partition your sdcard (ext partition) and use the old style a2sd (apps2ext) using darktremors a2sd package you can run widgets from the sdcard. Along with putting the entire app, not just 1/2 or 1/4 of it, on the sdcard plus all of it's data (optional).
If it's easy for you to understand it as the phone thinking the ext partition is part of the internal memory, that's good enough since it's basically what's going on.

What you did wrong is moving the app to the sdcard. The commands you run in terminal move the apps to the sd ext partition. Specifically this one:
Code:
#su
#cd /system/bin
#a2sd cachesd
It will still show it as installed to the internal memory because it thinks it is. Even in a file explorer under data/app it shows the apps but that's part of the *trick*.
If you go into applications and move it to the sdcard it puts it on the fat32 partition which is where the froyo version puts them - don't do that. That's what you did wrong.

KCRic... huh i didnt know that. Ill try that. Spastic u should try that lol

Yeah. You can use titanium backup to make sure. Just open it and you should see a bar at the bottom showing sdext available/free. Also you can use a file explorer - got to /sdext and you should see an app, app-private, dalvikcache, data, and one or two other folders listed. If you do then it worked.
You can also use terminal to have a2sd check and make sure it's working but I don't want to load the thread with commands I'll post them if you want to learn a bit though

Sorry to resurrect this thread, I thought it better than making my own.
I'm running CM 6.1.3 and have an 8GB SD card inside.
1) How do I check how the SD card is formatted? And if it doesn't have an EXT3 partition, how do I partition it property?
and 2) Is there an easy, non-terminal way to send apps to the EXT3 partition, akin to hitting "move to SD card" in android settings. And since, as you said, it moves all the data to the EXT3 partition, not just some, is it best to keep most of my apps there, to free up internal memory as best as possible?
And PS, when I'm partitioning my SD card, will I need to create a SWAP partition? 1GB for an 8GB stick?
Thanks so much.
EDIT: I'm on an X10 if that helps..

[Q] Abit Of Help Please...

Am using Leedroid App2SD+ ROM and have 1gb ext with 756MB free, i have lots of apps installed but now my phone is showing low memory 15MB, so I have moved alot of the apps to SD card to try free up abit, but its not freeing up phone memory its still staying at 15MB.
Why wont all apps just use the ext? how do I get free phone memory back up again.
All help welcome thanks

All apps have to use internal /data/data folder to store libraries etc. So if you need more storage read about data2sd.

Because if you have A2SD+, then Move to SD in the application manager has no effect (apps are already on the SD Card).
Try running a cache cleaner, maybe too much cache. Possibly a2sd+ is not working properly?
I never had that much low space on LeeDroid when I was using it (had 55 apps of my own installed).

check the leedroid topic?
I read something about a memoryleak in flash what could cause the problem.

You can also move dalvik-cache to sd to free about 40MB internal memory.
Simply download terminal emulator from market, and then put su and a2sd cachesd or cachesdreset (it removes old dalvik cache from internal memory) commands.

Here you have zip instalation scripts and some tutorial how to manage that:
http://forum.xda-developers.com/showpost.php?p=10692249&postcount=1299
Remember that you will lost your apps! Backup them by Titanium Backup (I don't think that backup and recovery by nandroid it is best solution if you are messing with symlinks and /data partition).

I never had any issues like yours when I used Lee droid A2SD and had installed a lot of apps. Just make sure that you have not moved the apps in the app manager to the SDCard as this only movers them out of the Ext partition and in to the FAT32 partition.
I would give Leedroid another shot with your new SDCard.

I think I have just filled it lol got 75 apps but most of them are games big files, ill give starburst a go liking the sound of this ROM and if its true I should never fill the memory, if it not good ill go back to leedroid but start fresh format everythink.
With my old partition I did make it on windows like, so maybe thats whats happened, I am going to use gparted next time.

Apps2sd

my ROM is a apps2sd ROM. Ext sd is reporting use, i.e. I set 1g of ext and storage says 658mb of ext is free. But in applications my apps give me the choice to Move to SD! ?
I used TB pro to batch move apps to SD but altho my apps now report they are on SD. Ext usage actually went down after the move. Am I confusing Apps on Sd / ext ? So on roms with default apps2sd you ignore in applications that they appear to be on internal mem?

Yes ignore it. You've just moved your apps from ext to fat. Read the root memory faq in my signature

I've some A2SD questions as well. I'm on CM7 with several apps already installed. My 4GB SD card has already been partitioned to 3GB FAT32 and 1GB ext4.
I was getting low memory warnings so I applied the darktremors script (stable, not nightly) expecting it to automatically move my apps to the sd card like your a2sd guide said it would. However, I still got low memory warning, so I manually moved the app to sd card using manage applications. This however moved the apps to the FAT32 partition, and several of my apps suh as my clock widget and swype no longer work.
How to I get my existing apps to move to the SD card's ext4 partition?

They need to all be moved to phone.
The apps should automatically move to ext download quick system info to check a2sd is working.
If its not try "a2sd reinstall" from terminal emulator.
Dalvik-cache is not moved by default and takes up a whole load of space so don't forget "a2sd cachesd" too
Sent from my HTC Desire using XDA App

OK, I thought the a2sd would move existing apps as well, didn't know I needed to "a2sd reinstall". Can I do the reinstall through an adb shell or do I need to download a terminal emulator?
I don't have a Class 4 card, it's a generic card and I don't know what class it is, so should I move the dalvik-cache to the cache partition using "a2sd cachepart" rather than "a2sd cachesd"?
Do I need to wipe cache and dalvik-cache before running any a2sd commands such as reinstall and cachesd/cachepart?
Lastly, do I need to reboot the phone after running these commands?
Thanks.

Ive never seen any performance issues even on class 2 cards. Keeping dalvik on NAND may give a miniscule performance increase, but I think its so negligible, you wont notice. But put it where you want. I recommend card though as you need the cache partition for downloads and as it fills with dalvik, it will limit the size of apps you can download from the market.
a2sd reinstall is for if it doesn't work properly. Its always the first thing to try. Then move dalvik. The way dalvik move works is that it wipes dalvik, moves the location then reboots the phone (rebuilding dalvik so expect delays when booting up the first time). For this reason its best to use "terminal emulator" from the market.
Hope this helps.

Alright, thanks! Will try reinstall and moving dalvik cache to the sdcard. Might get a new faster card since 4GB is getting tight anyway.

Tried the reinstall and it seemed to work. I had to move my apps back to the internal memory in 2 batches since I was running out of internal memory. So here's what I did
1. Move batch 1 of apps from sdcard back to internal memory
2. Run a2sd check in adb shell
3. Run a2sd reinstall in adb shell
4. After phone rebooted, checked my storage to find about 50MB of internal space left (woohoo!)
5. Move batch 2 of apps from sdcard back to internal memory
6. checked my storage to find still about 50MB of internal space left. I guess this means a2sd automatically moved them to the sd-ext partition?
When I ran a2sd check in step 2, the output showed that my ext partition type was ext2 rather than ext4 which I formatted the sd-ext partition to. Is this a mistake?
Will try moving dalvik-cache perhaps this weekend.
Are there any benchmarks I can run on the sdcard to make sure it's fast enough for dalvik-cache? Perhaps HDTach/CrystalDiskBench/ATTO/AS-SSD Bench/etc? There aren't any markings on the sdcard that indicates its class. It's a generic HP 4GB sdcard. Will a "dd if=largefile of=/dev/null" for read and a "dd if=largefile1 of=largefile2" for write work?

I've never known a card too slow for dalvik. Just move it. You can move it back again
Sent from my HTC Desire using XDA App

I believe the ext2 is due to some error with a2sd check. I encountered it too when i used the command and i was using an ext4 partition.
As for dalvik, try moving it. If it too slow then move it back.

Sorry, yes its a bug, fixed apparently in the latest BETA.

Don't think I'll be playing with the phone for a while - it's my wife's phone, and it took almost a week for me to figure things out and start from stock to CM7 with A2SD...now it's relatively stable with quite a bit of internal memory available, so I think I'll keep it that way for a while.
Thanks for all the help!

Hello rootsu,
i installed a Data++ rom and now some applications that i install, not from market, disappear after a reboot. From the market it is fine but if i put a .apk in the card and install it, disappear after reboot. Not all of them. Only some of them.
I have a aura sygic gps and this is one of them that disappear after install. The only way that doesn't is to move to the card. And another one, that doesn´te have the option to move to the card, disappear after reboot.
I already wipe dalvik cache, wipe everytnhig, rom install again, etc...
What's the problem? Do you now? I've searched a lot but i cant find anything.

That's a new one on me.
Install, take titanium backup, boot recovery, factory reset, format /data, titanium restore?

Thanks, rootsu.
And when i go to install again, say that this will replace another application.
I already made a backup, when i have stock, and restore it and happens the same.
What to do?
Edit: I do a backup, only the application, with titanium, and when restore it and say error and dont restore the application.

Hello rootsu,
i install hboot sense and Leedroid 3.3.3 and works fine, but i have a question about cache file system. Why my cache system space is 202mb? In the AlphaRev 1.8 page the hboot sense as 40 mb. I dont understand.
The cache system space is from sdcard memory or memory phone?
Thanks

Although I am not rootSU, I feel free to answer:
I am pretty sure it uses space of SD Card. Using internal memory would be a little strange, especially we are talking about 160 MB here.

[Q] A2SDGUI not working on rooted Desire

I have installed the LeeDroid ROM v3.3.3 Port R5 on my Desire and I downloaded the A2SDGUI app from the market. But it gives an error saying phone is not rooted (which it obviously is) or A2SD scripts not found or ext partition not found. How do I make this app run on my phone? I have Superuser installed and A2SDGUI is given permission. Kindly help.
Thanks in advance!

Did you configure your SD Card with a FAT32 and an EXT partition?

Yes I did. I have followed all instructions given for LeeDroid's ROM properly. I used GParted Live CD to make the FAT32 partition and a 1gb ext3 partition on my SD card.

Followed guide on Leedroid thread to get A2SD working?

You know a2sdGUI only works with Dark Tremor a2sd scripts? I dont think leedroid uses Dark Tremor.

@Matdroid
Before installing LeeDroid I had created the ext3 partition. I presume A2SD is working because my apps are installed to the ext3 partition and not in the internal memory. Do I have to do anything else?
@rootsu
Then A2SDGUI wont work on my phone?

Not right now. Not without the Dark Tremor a2sd+ Solution in place.

If you followed leedroid guide for A2SD+, you don't need A2SDGUI.
SwiftKeyed from CyanogenMod with Transparent XDA App

The only reason I was looking for the A2SDGUI was to try to move the dalvik cache to ext partition. Or is it already in the ext partition in LeeDroid ROM? I dont know.
Also inspite of having a ext partition my internal memory is getting reduced bit by bit with every app that I install. I thought I had got rid of the 'lack of internal memory to install apps' problem by having an ext partition. What data is occupying the internal memory now?

Apps still take up the space on Internal memory. Thats the way it is.
You have to flash the dalvik cache script in the leedroid thread, post 1
Like Mat said, if you read the thread, you would know the answer.

I have downloaded the 'move dalvik to sd.zip' file from LeeDroid's thread. I read somewhere that A2SDGUI also does the job so I wanted to try it out. I guess I will just flash the zip now. Thanks for your replies.

Appreciate all you guys taking the trouble of answering my questions. I really have very little knowledge of rooting and stuff. Just venturing in this field. So far I have managed to read the guides posted here and root and install a custom ROM. Now trying to understand dalvik cache and stuff.
Thanks once again.
