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stated, cyanogen's rom does this automatically (most do now), and installing apps2sd will (i believe) implement an outdated/slower method of 'symlinks'.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)

Ok , tried reflashing, no effect it seems. ... from what I've seen the thread on partitioning was pretty much the same as the one I used.

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)

[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.

works like a charm...took your suggestion and resize the partition...exact results

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.

Google for bootice..install and launch it...then select your sd card in physical disk...go to parts manage...select reformat...then format it into USB-HDD single partition with fat32 format...Hope it helps...

With GPartEd you can fix it. Google for it.....

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.

[CM11 for Cooperve5830i][BOOT Image] - Using the SD card for Data partition

Using the SD card for Data partition
I was very happy to find that great work has been done to bring CM11 to the Galaxy Ace s5830i.
Thanks to all those involved!
After installing it I found that although CM11 is awesome the Galaxy Ace is crippled by the lack of internal storage.
To fix this I created a boot.img that is a repackage of the boot image that ships CM11.0.0 RC12.
This boot image tries to mount the second partition of the SD card on mount point /Data
Hopefully this work may be useful to others.

Note: I do not have the credit to post this on the dev board.
Instructions:
1. Backup the phone (all data etc).
2. Configure a SD card with two partitions (see below) and insert it into the phone.
3. Use CWM to get CM11 installed and running (CM11 RC 12 or later) see the XDA forums.
4. Using CWM flash the modified boot image (cm-11-RC12-cooperve-boot_img-sd_data_ext2.zip).
The SD card must be configured to contain two formatted partitions:
1. Partition one should be a FAT32 partition.
2. Partition two must consist of a EXT2 formatted partition.
The first partition will be used in the traditional way and the second partition will be used as the data partition. I use a 32GB sd-card with the first partition (fat32) sized to 24GB and the second (ext2) sized to 8GB.
NOTE:
1. Use at own risk, this may damage your phone and eat your data!
2. If you have data on the original /Data folder you will need to take steps to copy it to the new folder if you want to keep it.
2. The SD card must never be removed while the phone is on.
3. The SD card must always be in the phone when it is on.
4. The recovery CWM will not backup the new Data partition on the SD card, it will backup the original Data partition.
5. If you update the boot image i.e. flashing a new version of CM11 sd-card Data partition will not be used. Reinstalling the modified boot image should fix this (untested).
6. I am not the first to discover this method of using the sd-card to store data.
Attachments:
Modified boot image CWM flashable: cm-11-RC12-cooperve-boot_img-sd_data_ext2.zip
Diffs of changes to the original CM11 RC12 ramdisk.

This solution could be implemented in cm11 in that defy solution was implemented in direct rom cm11. I wonder if someone used this solution in cm11.

OP3T switch to ext4 as f2fs has GC issues?

According to the Paranoid Android dev, "f2fs users should switch back to ext4 as f2fs has GC issues which can result in performance issues over time."
Anyone experiencing it and how to switch to ext4?

I tried formatting data, system, cache back to ext4 from f2fs, while installing a CM based ROM. But i got the internal storage formatted.
I used TWRP.

/data = data partition + internal storage memory
if you change file system on it, it will obviously wipe everything.
and you can't use f2fs on /system, it will change back to ext4 once you flash. you can use however f2fs on /cache.

Yes this works, but make sure to copy the nandroid backup to your pc before doing the change to ext4.
Or else it will get deleted!

If i make a backup while it is f2fs and then change it to ext4, if i restore the backup will it change it back to f2fs or keep ext4?

It will keep ext4 and you'll just get a note that the backup was created on a f2fs and you have ext4 at the moment.

There are few methods to do it:
1. by entering TWRP > Wipe > Advanced > check partition > change file system
2. by booting the system and using DiskInfo app
3. by executing ADB command
and so on.
