Test if apps installed on SD?

Just installed cyanogens rom and started adding apps from an 'appmanager' folder on the SD card- but I cannot see them in a seperate folder on the SD - is it just running them in the 'appmanager' folder? Or is apps2sd not working and installing stuff on my internal memory?
( I have 3 partitions by the way, one ext2 /3 not sure which, the last one a 'swap' from early 'hero' install)
Thanks

you need an ext2/ext3 partition for apps2sd to work. if you have such a partition then cyanogen rom is installing apps there automatically.

open an adb shell and cd to /system/sd
if there are some folders, the apps2sd is running (the ext partition is mounted under /system/sd)
You can also run this in terminal but there you need to run the "su" command first

Sorry, noob!
Ok I opened 'terminal emulator', did 'su' allowed root and then
cd /system/sd
'ls' to see directory right? just shows 'placeholder' so somethings wrong?
Is there an easy fix and can I move all the apps I just installed over?
Thanks!

looks like no apps2sd(the partition might be there, but no apps were moved at this time)
just create an ext3 partition on your sd card and install your favourite rom. cyanogen will move all apps automatic (long long first boot).
on other roms you might have to run the apps2d.sh script to move the apps. just read the corresponding thread for your rom. you will find all information there.

FireFart - you mean cyanogen? That's the one I installed, before adding these apps!
If I flash it again won't it wipe all installed apps?
Is it worth trying to run this apps2d.sh script?

try this guide:
http://forum.xda-developers.com/showthread.php?t=535232
When you just flash another update.zip, your apps wont get deleted(with and without apps2sd).
When nothing works, wipe, delete the ext partition and make a fresh install
To delete the content on the ext partition:
rm -rf /system/sd/*

I would agree with the thread you linked, however the apps2sd section is not necessary. as already stated, cyanogen's rom does this automatically (most do now), and installing apps2sd will (i believe) implement an outdated/slower method of 'symlinks'.
in short: use the thread for a guide, but ignore the app2sd section. its a good guide for the partitioning of your sd card (this part IS necessary)

you mean wipe it's contents right?

he means do a wipe on the recovery screen (ALT+W) AS WELL AS remove contents from ext partition.
the recovery console wont touch the ext partition when performing an ALT+W.
im not sure thats the issue though. just to verify, the order of your partitions on the SD is: FAT32/ext, correct? the FAT32 partition must be the first partition, and the ext the second.
EDIT: can u post the results of running a 'mount' cmd? you should have a line that reads something like:
Code:
/dev/block/mmcblk0p2 on /system/sd/ type ext3 (rw,noatime,nodiratime,barrier=1,data=ordered)

Maybe having 3 parts is throwing it? confused!

I could really use some help solving my A2SD+ problem

For the life of me, I CANNOT get A2SD to work properly.
ROM: MIUI 1.9.16
SD Card: 16GB w/ 1GB EXT4 partition
Problem:
When I do a fresh install of MIUI (wipe cache, wipe dalvik, wipe data/factory reset) A2SD+ in settings->system->storage says available and used are "0.00B".
If I use dark tremor a2sd install scripts, they 'claim' to have activated the space. It appears space is used on it too (around 100mb, despite previous wipe of all data which says it wipes SD-EXT). When new apps install they east away at my meager "internal" storage (IE: 20mb remaining) and my programs area says I ahve a total of something like 200mb of storage (shouldn't this change to over 1GB because of the partition?!).
As of right now I've restored my previous install, which says "0.00B" for A2SD+, and I have a 1GB EXT4 partition sitting here doing nothing.

a2sd is auto on MIUI after flash/reboot--shouldn't need to run scripts--but you can
try reformatting sdcard outside of phone and with sdformatter, then partition it as ext3 0 swap
ext4 never worked quite right for me
then fresh install with system/data/cache wipes 3 times each

Thanks for the reply. What's with this common habit of wiping 3 times? Doesn't wiping just unlink all the inodes from the partition table, then mark the sectors as free space anyways?
Anyway, MIUI at flash point never picks up this partition. I will try changing it to EXT3 and seeing what happens.

I am not a tech, but I think the phone doesn't do thorough job. That's why I format outside phone. Don't know for sure on System wipe, but most peolple recommend 3 or more times on data/caches.
I have been using these methods for quite awhile now and have much fewer flash issues between roms. Thanks to Temasek on his Format zips--------
ken

Well would you look at that. Fresh flash of the ROM with an EXT3 partition and it works! Didn't have to flash any DT zip. Thanks!
EDIT:
After using MIUI backup to restore my apps and stuff, I'm already out of space. My sd-ext isn't being used! how do I fix this?!

Your Welcome--

Sorry for double post, but I spoke too soon. A2SD still doesn't appear to be working correctly. I've attached a few screenshots to help show what I'm talking about. Titanium backup doesn't see the space (I don't think) either. It appears MIUI sees the space available... but doesn't use it. I just did an a2sd zipalign, followed by a a2sd cachesd to move the dalvik cache to the SD card which helped my space woes a bit, but my a2sd partition seems to be completely unused, other than the dalvik cache!

I can't view your thumbs, get error on page. May be my work computer
Had that happen once and a2sd was doing its thing, just not showing in Root Explorer as ext being used
Do you have any low mem warnings
You could try Quick System from market and see what it says

Your A2SD is working fine. As you can see, you have >100 MB of apps installed on it (0.94GB SD-EXT partition size, 832MB free). The reason you still see your internal memory being used is - 1) Dalvik-cache is still on the internal memory, 2) App data is still on internal memory. You can change that in A2SD GUI settings. If it tells you that Dalvik is already on SD - it's lying, the app isn't too correct, the script is much more correct. You can run the script to move Dalvik to SD in that case.
And the integration of A2SD isn't system-wide - actually, the system has no idea that A2SD is present, and doesn't report anything else for its partition sizes but the original sizes.

Jack_R1, after a random soft reset occurred, titanium now shows the a2sd. Thanks for clearing some of the information up for me.

[MOD]mount internal sdcard as /data CM7 and MIUI only

​
if you use cm7 or MIUI you may feel like your internal sdcard is a bit waste of memory
people have been trying to merge the internal sd partition and the data partition sadly without succes
but i tried to mount the internal sd as /data and i did succeed
i recommend you to change the size of your all your partitions using nvflash this is not necessary but you will have have more benefits
here is a link to the TUT on modaco
i used this values:
/system (512 MB): size=536870912
/cache (512 MB): size=536870912
/data (256 MB): size=268435456
Recovery (50 MB): size=52428800
resized system to 512 MB is enough
resized cache to 512 MB to store the dalvik-cache on the cache partition it is more use full then store it on the /data partition
resized data to 256 MB because we don't need it anymore
the remaining space will be used the internal SD well lets say it is a lot in my case it is as you can see on the screen shots above 5.43 GB
WARNING! YOUR SDCARD MUST BE MOUNTED ON /mnt/sdcard AND NOT ON /mnt/emmc OR /mnt/sdcard/_InternalSD OTHERWISE AFTER FLASHING YOU CAN'T ACCES YOUR SDCARD
IN CM7 THE DEFAULT SETTINGS ARE GOOD UNLESS OF COURSE YOU CHANGED THEM TO MOUNT INTERNAL SD CARD ON SDCARD
AND BY DEFAULT ON MIUI THE SETTINGS ARE WRONG THERE IS THE SDCARD MOUNTEDN ON /_ExternalSD
converting the internal sdcard to ext4 is not hard
you can just flash THIS zip for it
when your internal sdcard is formatted as ext4 you can use THIS zip to transfer your data to your internal SD partition
this zip contain 2 script
one will transfer your data over to the internal sd partition
and the other will transfer your dalvik-cache over to the cache partition (when there is enough space to do so if it is not resized it will just leave it on /data)
after this when you boot up the device you will notice you get an notification what will say it is safe to remove the sdcard
this is because it can't mount the internal SD and this will cause a bug you won't be able to mount your external sdcard on the computer
but hey we gonna fix that!
i recommend you to use root explorer for this job
locate /system/build.prop and delete these lines out of the file
for CM7 delete these
Code:
# Mount the internal SD card, too
ro.additionalmounts=/mnt/emmc
ro.vold.switchablepair=/mnt/sdcard,/mnt/emmc
for MIUI delete there
Code:
# Mount the internal SD card, too
ro.additionalmounts=/mnt/sdcard/whatever-the-text-is-here
now reboot your device and enjoy your huge space
Good Luck!
Owain
Huge thanks to benee for his universal ext4 converter that i used to convert the internal sd partition​
i am in no way responsabel for whatever might happen
to your cellphone if you did something wrong don't come
and blame me for it it is your device you did it​

I'd appreciate it if you made it a little less complicated for not-so-advanced users like me. :/

Works great! Thanks.

MicroSDHC problem

I am using a 16gb G.Skill microsdhc class 10. I used MiniTool Partition Wizard to make 2 partitions, it show 14gb+ of unallocated space. I made the following partitions without any problems.
1: 1gb primary-ext 4
2: 13gb+ primary-fat32
I followed these steps by mor_1228 to install the Apocalypse Final ROM
1. Do a fresh install of stock rom via odin i recommend XXKPT = Russia 2012 March
2. install latest recovery.
most important procedure
3. switchoff then press only home button and power button
1. wipe data/factory reset.[imp]
2. wipe cache partition.[imp]
3. Go to mounts and storage and format these :
a. system
b. data
c. cache
d. sdext
4 go to advanced and then in there format :
a. Dalvik cache
b. Battery stats [not imp.]
4. Install apocalypse latest final version.
5. install layout properly as suggest in developer post. after installing layout reboot 2 times.
6. mount system and install AMARULLZ DATA TO SD-EXT
7. give 2 reboots after installing AMARULLZ DATA TO SD-EXT.
8. check ur internal memory it will be according to ur partition size.
9. [if error] if u find internal memory still same then u must have not mounted system go to recovery again and mount system and then flash script again.

Here is where the PROBLEM started :
I was in CWM 5 recovery and was about to flash the Apocalypse Rom but I can't seem to find the CM7-APOCALYPSE-090712-FINAL zip file to flash, I rebooted the phone normally and it showed that my microSD is blank. Then I connected my sdcard to my pc but it isn't recognized anymore.
Opened Disk Management in windows and saw that my SD card only has 1gb capacity. Minitool partition Wizard also showed 1gb. I tried the Partition recovery wizard but didn't get any success. Also tried EaseUS partition master but the same result.

When I try to make that 1gb a partition, it show Bad Disk under File System, when I try to use CWM to make a partition, it just gets stuck in the partitioning part. Same with when I try to format it in windows, I also used SDformatter, HP Partition Tool, and other similar apps that came up when I search in and out of this forum for answers but they all just get stuck at 0% and wouldn't progress forward.
Any ideas how I can fix this?
Any help would be very much appreciated. Thanks!

still no luck finding a fix. anyone have an idea what to do?

any ideas?

You can formate your sd normally with windows and do again the partition.

Try to format the sd card with windows again...before putting files into it, partition the sd card via cvm in advanced (do not put things as the whole card will be automatically formatted)...after that, start to put things into your sd card...do not format sd-ext again this time and keep in mind that any windows program will report the partition as corrupted the next time you connect your card to your pc again...it's normal as sd-ext formatted by cwm are like that, but it's effective...

First of all, thanks for your suggestion!
I can't format the card anymore. When I try to format it in windows, and using different formatting apps like SDformatter, they just get stuck and wouldn't progress. Sometimes the apps i used just stops responding.

I tried GPartEd but it also didn't fix it. It said that there was no partition table. But when I tried to Write a Partition Table, there is an error I/O error with the device (Cyclic Redundancy Error). I thought it is caused by the write protect but the write protect is disabled. And another weird thing is when I first inserted the microSD, GPartEd listed that it has 14.97gb unallocated space, but after reinserting it after I checked for write protect, it recognized only 1gb again.
I think I'll just get a replacement for this card. Thanks everyone for helping!

Use CWM to partition it. It's under advanced.

[SCRIPT] Dalvik To Cache | No Loss in performance | Extra Space In Internal Memory

Please tell me the error you get, i will help you in solving it
This is made for stock kernel, althought it will work most probably on every kernel and rom.
---------------------------------------------------------------------------------------------------------------------
-------------------------This is a Easy Way to Increase Internal Memory-------------------------
---------------------------------------------------------------------------------------------------------------------
It Moves System Apps Dalvik Cache to the Cache Partition in Your Internal Memory, with no loss in performance
Use This On Your Own Responsibility, I Will Not Be Held Responsible For Anything
I have Tested it on my Arc S and got 60mb more free, I have a total of 67 apps installed

(both provided codes which i read and understood)
Compatibility:
It Should Be Compatible With Most Phones With a Cache Partition
Requirements:
Please make sure u are rooted
Please have the latest busybox, To install busybox : https://play.google.com/store/apps/details?id=stericson.busybox
An app like Script Manager ( I use : https://play.google.com/store/apps/...GwsMSwxLDEsIm9zLnRvb2xzLnNjcmlwdG1hbmFnZXIiXQ..)
Also a Rom/kernel that has Init.d Support ( I use this guide to add init.d support to my rom : http://forum.xda-developers.com/showthread.php?t=1405590 )
Also Please Make Sure You Have Your SDcard Inserted on reboots and that you have around 50-100mb free in your SDcard
Instructions:
Download The Files
Run 02SystemDalvikToCache Using Script Manager (Only need to run once)Run as SU
Put 02DalviktoCacheBoot in Your Init.D Folder and set right permissions
To Uninstall:
Remove The 02DalviktoCacheBoot script from init.d folder
Reboot to recovery And Wipe Dalvik Cache (Or you can use an app that wipes dalvik Cache)
FYI:
02SystemDalviktoCache moves System Applications Dalvik Cache to the Cache partition
02DalviktoCacheBoot copies Dalvik Cache from sdcard to Cache partition to prevent Bootloop
Ignore All Errors Given By Script Manager, They Do Not Affect The Work of The Script
The reason i dont have a script to move dalvik-cache of apps in sdcard is because they are usually higher than 100mb, if i need some more space, or if these scripts are used i will make a script to move sdcard apps dalvik-cache to dev folder
If you edit your system apps, and are getting low internal memory again, please wipe dalvik-cache and then run script again
Download:
https://www.dropbox.com/sh/5ertwdtb17bciwa/pTaaxewnJX
If You Get A Boot loop, Please Go Into Recovery, Wipe Dalvik Cache and Reboot
Warning: Please watch out that your cache partition has around 100mb limit (102mb on arc s)
Important: Please make sure to read the instructions and also the FYI section is very helpful
[SCRIPT] Dalvik To Cache

Hi, I have a few question to ask:
1) what is the benefit of using this?
2) how will this impact the performance of the phone and battery life?
3) will this damage my sd card in long term usage?

1) A lot of ppl have trouble wid low internal memory, this will give u about 60mb extra in internal memory
2) Not Really, my phone is exactly the same as before,it might be a little faster, jst have more internal memory , which hence makes phone faster, and more space for app cache's in /data partition
3) This does not affect SDcard in any way, it just makes a backup of ur dalvik-cache in sdcard to tansfer it to cache partition at each boot (cache partition sometimes gets formatted at boots, this is a precaution to prevent bootloops)
Edit:
Cache partition is a partition of the internal memory, which has 102mb in arc s, usually only 2mb is used, CM already has a built in script tht transfers dalvik cache to cache partition, this is mainly for stock roms
Sent from my LT18i

Before this script i had 70mb free in my internal memory
Now i have 130mb free
(both values are approximate)
Sent from my LT18i

*UPDATED*
Whenever you run the script, previous dalvik-cache's in cache partition and sd card will be deleted to prevent dalvik-cache of deleted apps from taking up space

Either you didnt put the init.d script into the init.d folder

Could you check something for me?
go into ur sdcard
and check if there is a folder called dalvik-cache
and check if there is anything inside it
if there is then go to ur root directory and check inside the cache partition and see if there is a folder called dalvik-cache there and if anything is inside it
