Do i need Link2SD? - Optimus One, P500, V Q&A, Help & Troubleshooting

I've been using titaniumbackup to move apps to sd but my system partition is full now and theres nothing i can do.Will a script like Link2SD or others fix this?

No If you don't have an ext partition.
Backup all your apps (almost data) and make a new fresh install of the rom. Before flashing create an ext partition from recovery.
You can use link2sd or whatever script you want. I've always used link2sd because of its full control of installed apps (link/unlink/move to system, etc.) Now I'm very happy with int2extv2+.
But as anyting on android it's all about personal tries and choices.

As we have a very meagre system space, it becomes as much as a necessity to use different '2SD' scripts like Link2SD on the phone to enjoy our favourite apps..i use Link2SD and am very happy & satisfied with it..

New to CM7

Hi all,
So last night I decided to give Cyanogenmod7 a try. I came from MIUI.us 2.1.20 - I just love MIUI, but it's a bit too demanding for the Milestone. So I have CM7 up and running, and it is a lot more snappy. But now, I'm having trouble installing some apps.
I tried installing my bank's banking app, but it didn't install - checked the market and it doesn't appear. Same thing with WhatsApp!! If it were working, I might just become a CM7 user..but it's not working.
Am I missing something? I installed after doing a full wipe, after which I installed DT A2SD scripts and then gapps-20111216 (although didn't see gmail or market etc after gapps, so installed those via apk).
What's the deal here?
Thanks.

Ok, just wiped again, and reinstalled all. CM7 then gapps then dt a2sd. So far it's working.

googleservicesframework.apk and vending.apk are all you need for using market. Try to reinstall them. May you success.
Ok, so now my problem is A2SD. It's not working! A2SDGUI refuses to go in, and when I do a check, I get a segmentation fault...I've never had this issue before. I've tried reinstalling DT A2SD from withing recovery and still, nothing. Please assist, I just need to get set up properly now.

DT scripts dont work ...use an external partition (app2ext)
d.casper.b: CM7 for Milestone already comes with its own ap2ext scripts that are automatically used if there is ext partition present on your sdcard.
You should not install any 3rd party app2ext scripts as they are very likely to be conflicting with the scripts that are already there.
Thanks kabaldan.
I'll check it out.
I was even going so far as trying to use Link2SD from the market..
How'd I know if it's working? By monitoring the available internal storage?

when you will enable app2ext you will see the total space in your storage rise to 197 mb
I am not winning. I did a factory reset and flashed cm7 and gapps (not dt a2sd).
I did a test, internal storage was at 191mb, then I installed opera mobile and it went down to 182mb. Then uninstalled it again. Went into cyanogenmod settings and set install location to external. Installed opera again, but it was no different. Moving it to sd under 'manage applications' increased the internal memory again, but that's just moving the app to the FAT32 partition of the sd card.
So it's not seeming to work for me for some reason.

EDIT: I really don't want to be a nuisance, but now, looking at the available storage using "Quick System Info", I noticed after uninstalling "Opera Mobile", 9mb was freed on internal storage & 13mb on the ext partition.
So, perhaps it is working, and since the dalvik cache is (I assume) on internal storage, the storage is still decreasing. Am I correct? If so, is there a way to also move dalvik cache to the ext partition - I had it like this on MIUI & never looked at available memory ever again.
First of all, have you really partitioned your SD card? Make sure you followed the 3rd step on this guide: http://www.mrmuh.com/2012/01/update-a-motorola-milestone-from-motorola-firmware-to-cyanogenmod-7/ . You should have your SD Card partitioned with two partitions, the first should be FAT32 that's used normally on Android, and the second EXT3 or EXT4. Obviously, make sure you have a backup of your FAT32 partition before partitioning.
Second, you should understand how the apps2ext scripts on CM7 work. Application installs that would be stored on internal memory are rerouted to the EXT3/4 partition on the SDCard. This happens at the underlying system (linux) level, Android (that runs on top of linux) is not aware of this rerouting, so, as far as Android "knows", apps that are rerouted to the EXT partition are on the phone's internal memory. That means that you should make sure that apps you need installed on the EXT partition of the SD card are shown in "Applications > Manage applications" list to be installed on the internal memory. Yep, it's confusing, but once you understand how it works and why it works that way, it makes sense.
Third, the fact that apps are rerouted to the EXT partition doesn't mean that everything about the app will live on the ext partition: it means only the main application package will live on the ext partition, application data is still stored on the internal memory. For most apps, the amount of data used for application data are much smaller than the application package, but in some apps the amount of application data from the app may often surpass the size of the app itself - for example, in my phone, Tweekdeck stores about 9Mb of data, which is about 10 times the size of the application itself (820kb) - presumably this amount of data is cached tweets, pictures, etc. But that case is usually the exception, not the rule, I've just mentioned it so you understand that using apps2ext doesn't mean your internal memory will always stay unused, it just means it will be used (way) less.
Finally, regarding the CyanogenMod Settings location setting, if you understood what I said above, you should now understand that it should actually be set to always install to "Internal", rather than external. However, there's a bug in this that you should be advised, that not all apps will respect this setting: some apps will install to external regardless of how you've configured that setting (meaning the app will use Froyo/Gingerbread native Apps2SD, hence being installed to the FAT partition of the SDCard). So, when you install a new app, check on app management if it didn't get installed to the SDCard, and move it to the internal memory if that's the case. For these kind of apps, you'll have to do it every time you update the app too.
Thanks, I edited my previos post..
I actually have 3 partitions, a FAT32, an ext2 (maybe it's ext3, but doubt it - partitioned some months ago, so my memory's hazy), and a SWAP - which I should get rid of, but am too lazy.
I understand entirely what you've said, I know that internal is really ext if working, and sd is FAT32 partition.
You see, I'm just new to this rom and have to trial and error until I understand, with miui you just flashed the rom and the a2sd scripts and didn't bother again (maybe only to move an app that installed to FAT partition). But it seems CM7 is simply just to flash the rom and you're good to go. But as I was pondering in my previous post...is there any way to move dalvik cache to ext?
Thanks for putting up with me..I'm almost there.

in the market you will find an app called s2e which moves app data, davlik cache to sd
also link2sd also free's up more space and makes cm7 snappier
please don't install such things to CM7 for Milestone unless you know what you are doing and you are able to resolve conflicts with the existing scripts
dalvik-cache is already moved automatically
if you want to free more space in /data, enable lib2ext to move native libraries to ext - it's mentioned in the changelog for 7.1.2 release
app data itself should not be moved as it can cause instability

Yeah, get rid of swap, there won't be any use for it (for now anyway) and it's best for you at this point to have a known working structure (two partitions, 1st FAT, 2nd ext3/4) for your SD as you're troubleshooting your problems/questions, it'll make it easier for us too as this will eliminate potential points of failure or inconsistencies. And you should really consider upgrading to a journaled filesystem, either ext3 or ext4. Using ext2 is unreliable because Android doesn't umount the ext partition cleanly on reboot or shutdown, so you may have problems with apps disappearing or misbehaving every other reboot. Using ext3/4 with journal elimitates this problem since the journal is just replayed for the uncleanly umounted partition and the filesystems behaves more consistently.

The apps2ext script built on CM7 should do this by default - you probably already have your dalvik-cache on the ext partition. To check this, go into OR, enter the console and type: "ls /sddata/dalvik-cache" . If it returns a list of files, you've already got the dalvik-cache on your ext partition. Another option is setting the option dalvik.vm.dexopt-cache-only to 1 in the file /system/build.prop . This will put all dalvik-caches (both from user apps and system apps) on the phone's internal cache partition, thus still freeing space on the internal memory but without using the ext partition, but that's not recommended if you install too many apps because the cache partition may run out space and that will spawn all kinds of weird behavior on Android. The safer route is just using the default configuration anyway (user apps dalvik-cache on sd-ext).
Another option to further reduce internal memory use is using lib2ext, that will move user apps native libraries to the ext partition, but the memory gain in this case is dependent on which apps you use and how big their native libraries (if they even have one) are. To activate it, just go into the Terminal app (with Android booted) and type:
$ su
# lib2ext
And reboot. The libraries will be moved to the ext partition during boot. Make sure you have a big enough ext partition to hold everything (apps, dalvik-cache and apps libs) - the size to recommend is very dependent on how many apps you use and how big they are, but I'd say 512Mb would be the bare minimum.
in the market you will find an app called s2e which moves app data, davlik cache to sd
also link2sd also free's up more space and makes cm7 snappier

DON'T! JUST DON'T! These third-party apps will cause all kinds of problems with CM7 builtin apps2ext.
EDIT: Oh well, Kabaldan already put all my rambling much more succintly than I could... I'm way too talky
well i was jus trying to help.. .anyway guys thanks i guess i won't be needing those apps anymore ...sorry for my noobness
Thank you so much guys!
It seems like it's working. I will check out lib2ext & the other suggestions tonight or over the weekend (on my way to work now).
I must say, I thought the move to CM7 would be a temporary one, but the speed gain is just what I needed, & the tweaks I thought I'd miss I am finding hidden in the settings .
Just wondering on the battery now - but I've been fiddling non-stop.
So let me play a bit more the weekend & I'll merge my ext2 and SWAP partition into one ext3 partition.
Thanks all, and kabaldan for your hard work on this rom.

Just as I was on my way...
Everything's running fine, A2SD works. But now, I partitioned my SD card with a 2nd partition (ext3, it was ext2), but now widgets are not loading. Checked the apps install location, and it's 'internal', ie. ext3. I never had this before. I think maybe it's due to the filesystem now?
EDIT: Ok, ext2 is doing the same. I can't keep starting from scratch the whole time guys.
EDIT2: It's now suddenly working! Just have a Fat32 and an Ext3 partition. But I don't understand because it's been setup like this twice before with no success. I'll hold thumbs!
PS, CyanogenMod is quite up my alley now, speed is awesome and I'm happy.

How to get more internal space on galaxy fit

firstly I'm not responsible for any kind of damage caused to you
but I have tried all the things on my galaxy fit before explaining here
It's not copied from somewhere instead It's based on my experience on my galaxy fit.
For Non Rooted Devices
There is nothing other then using app2sd apps. Then move all the movable items to sd card. After installing app2sd all newly installed apps are automatically moved to external storege.
I uses app2sd by sam lu.
But for non rooted users I will highly recommend to root there device and make the best use of this smartphone.
for beginners everything about rooting/custom roms/nandroid backups etc is explained in this thread
http://forum.xda-developers.com/showthread.php?t=1606380
thanks a lot to A.cid for this wonderful guide
For Rooted Device
apps required
1.Root explorer or similiar
2.Link2SD (Link2sd Setup is explained later in this post)
step 1.Removing Useless system apps from stock or custom rom
go to /system/app using root explorer and mount as r/w
now delete unwanted apps
I will prefer freezing the app first using link2sd and then if phone is working fine then you can unfreeze and then delete that app
Step 2. Removing dalvik cache files
go to /data/dalvik-cache
now search for the dalvik cache files of deleted system apps
it will having name like
[email protected]@[email protected]
delete this file
Step 3. Linking files to Sd-ext or second partition of Sd card
if you have finished Link2sd setup then you can proceed further
open link2sd and then create Link for all the apps you want to linked to sd card
check all the 3 box 1. link apk 2. link dex 3. link lib files
and then your app will be moved to the sd-ext partition
if there are apps which are used very frequently then i prefer not linking dex files to sd card. link only apk for them.
currently system apps can't be linked using link2sd
In the case if app is not working properly after linking then remove links for that app.
Plz help me to improve this article.
suggestions and questions are welcomed.
forgive me for my poor english
Plz help in improving this article. If there is anything wrong in this post let me know. and if you have any other simple method to do this plz post here and help beginners to get more space. But try not to post complicated method which beginners find hard to perform

Link2SD steup on galaxy fit
Copied from A.cid main article from
http://forum.xda-developers.com/showthread.php?t=1606380
There are a lot of ways and scripts to transfer apps from your internal memory to the sd ext partition, but the most consistent method I found was Link2sd.
This method works across all roms (rooted stock and custom, both) that I’ve tried, even on all variations of CyanogenMod7 (CM7) as well as on ICS CM9, and is very easy to setup and use.
However, if a custom rom already has DarkTremor's a2sd (a2sdgui app will be present) or any similar script, then DO NOT configure them.
for example: Creeds v3 has a2sdgui, and if i want to use Link2sd, then after flashing Creeds, i SHOULD NOT run a2sdgui, and directly install (and configure) Link2sd...if you run/configure a2sdgui, then it will clash with the working of Link2sd.
Similarly, if any custom rom has any memory hack already implemented, then you cannot use Link2sd...
Steps to setup Link2sd:
• Download Link2sd from Play Store (it’s a free app).
• After it gets installed, run it, and allow root access.
• You will get a message to select the format of your sd partition, select “ext3”.
• Link2sd will then automatically create mount scripts that it requires to work, and will then tell you to reboot your phone.
• Do a proper reboot, and not a ‘hot reboot’.
• After rebooting, open up Link2sd, press menu then select “settings”.
• Select/check the options “automatically link newly installed applications to sd”, “auto link notification”, “relink lib files at boot” (and “fast scroll”, if you want).
• For “install location” option, select “internal”.
• Then go to “auto link settings” and select/check all the three options (you can skip/ unselect “link dalvik-cache file” if you wish)
• Done
Now, every new app that you will install will automatically be moved to your sd ext partition.
Link2sd is also an excellent (and fast loading) app manager, with which you can freeze, uninstall, re-install…though you can move only user apps to sd-ext partition.
Also, there is no point in having your entire phone memory empty, so you probably should unlink the dex (dalvik cache) of your apps. I usually link only the apk and lib files, and leave the dex files unlinked and on the phone storage, so as to avoid any sluggishness in operation., though if your phone memory still fills up, you can link the dex of your rarely-used apps, and leave the dex of important and frequently used apps on the phone storage.
Suppose a custom rom has s2e/app2sd pre-implemented, then after a fresh install, FREEZE the app (rather than uninstall), and then install Link2sd...
Also, if you get error "mount script not created", then choose partition as ext4 (rather than ext3 mentioned below), even though your partition might be ext3...(don't know why this happens with some roms )
In some custom Roms Link2sd doesn't mount sd-ext partition even after selecting correct type of partition in that case try to select other types whether they are working or not
Like in Chocobread v3.2 it worked after selecting partition as ext4

What happens when we install a new app??
I'm not a developer but this is what I experienced
/data directory is the space which is shown as Internal Storage in phone
/system directory has nothing to do with this internal storage
when we install a new app then it during the installation process three things happens
1.it creates an apk file in /data/app
2.creates an .dex file in /data/dalvik-cache
3.creates one folder in /data/data
when we move apps to sd that apk file moved to sd storage in
.android secure folder and creates an .asec file there
so basically that .dex file and data files are responsible for eating our internal space and for the apps which can't be moved to sd that apk file is also responsible.
we can't use widgets if app is on sd storage.
so in order to use widgets we have to move back to internal storage.
this is where Link2sd helps us
link2sd links selected files to sd-ext partition and for system it still appears in internal storage but it's not there actually.
While for system apps
.apk files remains in /system/app
only .dex files are in data/data directory
we can use widgets of system apps even apk files are not in /data/app directory
so it is recommended that if you want to use widget of the app but you don't want it on internal space(as it is using much more space while it is in internal memory)
here is the solution
create an apk file for that app using any backup app
then move that file to /system/app
change the permissions to rw-r--r--
for this simply see the permissions of any other system app and apply same here
to system

partition ur sd card through cm recovery then install s2e from play store now all cm7 rom come with pre install s2e script .
Another way is to use terminal emulator .
Download terminal emulator from the PlayStore and then run the following codes:
Code:
su
*grant/allow superuser permissions*
Code:
pm set-Install-Location 2
exit
exit
Note: sometimes if you get an error you may have to run
Code:
pm setInstallLocation 2
if it fails.
All this does is it allows moving many apps that aren't normally movable to the SD card. After running these codes you should be able to move apps to the SD card via Settings>Apps.
This code also sets the default location for apps to install into as the SD card.
What i do for more internal memory..!
Partitioning your sd card is an option. But if you have a sd card of less storage then this option is ruled out. I use a 2gb sd card and partitioning it is not very feasible for me. so...
1. If I'm on a stock gingerbread ROM i use this script http://forum.xda-developers.com/showthread.php?t=2303856 .
(I dont use it very often. Only if necessary.) And i odex the ROM if it is de-odexed by using http://forum.xda-developers.com/showthread.php?t=2303856 Universal Odex Script by MatrixDJ96. Odexing works very well!!! :good:
2. For a custom ROM not many modifications are needed. I just remove the unwanted apps using Link2SD. :good:

Link2SD Issues

Hello,
With the limited space on Optimus One I decided to try out Link2SD app. I was able to partition my SD card and Link2SD created the script. After reboot I tried linking some of my apps to SD (EasyMoney, Solid Explorer Beta2, Swype Installer and Swype). The first app (Solid Explorer) linked the app file, and delvic cache fine. Every app after that game me error: "Failure. mkdir failed for /data/sdext2/dalvic-cache, File Exists". Also, when I filter it to show only the linked apps even the first app isn't listed.
If I move only the app file it is successful, but every app force closes. Rebooting the phone simply forgets that I even had the applications installed (even after quick reboot). Finally removing the link does absolutely nothing. My guess is that the app never properly linked apps in the first place resulting in the app going into a 'limbo'. Now I have used some space in my SD partition and can't use the app or reclaim the space.
I am new to all this, but am researching what my fault is. Can someone point to what am I doing wrong? How do I get link2SD to simply move my apps to the partition to free up my internal space.
In a nutshell:
1. First app successfully moved, but link2SD still shows no apps are listed. Subsequent apps cannot be moved since dalvic-cache folder (or file) already exists).
2.. Moving only the app data results in FC. Rebooting results apps disappearing with no way to reclaim the used space.
How did you partition your SD card, and how is it formatted? Any other partitions on the card?
The SD card currently has two FAT32 partitions, both set as primary. Partitioned is using Minitool Partition Wizard.
Typically, the 2nd partition is formatted as ext2/3/4. If for some reason you need both partitions to be FAT, there's a setting in link2sd where you can specify that the 2nd partition is FAT. This is important because link2sd makes a script which is run when you boot up your phone, which mounts the partitions appropriately.
sorry if Out Of topic.
but anyone can tell me.
how to use link2sd.,.?
btw i'am using PARANOIDROID custom rom now.

If you have second partition on SD the Link2SD moves apps to sd-ext.
When starting the first time, make sure to select the correct filesystem. CWM makes ext4 I think..
If you are already by that with incorrect partition, go Options=>More=>Recreate mount scripts.
I recommend to activate Auto Link in settings to have no need to worry about apps being linked.
I think that's all what you need, if you are basic. I have done that too.

[Q] Best way for app2sd?

Guys I m newbie.
Want to know what is the best script or app or MOD which is best for moving apps and data to external memory and will help improving performance of our phone.
I am using Gingersnap 2.3 by neko, but s2e does not work on it?
Please hepl me with this.

I am a big fan of cronmod's scripts. You can put the script in the init.d folder of the rom's .zip before you flash it, or you can flash one of cronmod's .zips immediately after flashing a ROM (before first boot).
I like them because they are fully automatic. You can install tons of apps, and they get put on your sd-ext without having to link them, or do anything to them. I used link2sd for a long time before I found cronmod's scripts. After a while I still ended up running out of space, and I would have to go back into link2sd to figure out what ELSI I could link.
With cronmod's scripts your internal folders ( like /data or /data/app depending on the script) get automatically mounted to to sd-ext. This effectively adds to your internal storage. I see it as more of a fix, while link2sd is more like a band-aid.

Hi, thankyou for the tips, yes link2sd will not give you infinite space, once you start to have a lot of apps, them continue to write some data (cache, etc.) on your internal memory and this will lead you to fill your internal memory. So in my opinion with a non rooted phone, simple move app to sd is like a band-aid while link2sd on rooted phone is like a powerfull band-aid.
About the script, it will move ALL and let you to install infinite apps? I've readed that these kind of script give you also some stability problem on some apps and also decrease speed of the phone while for now, with link2sd i've no problem at all, I moved also gapps.

Im using cronmod (int2ext+) and I haven't experienced any problems, I guess (haven't tested) they just released a script that will work with 4.2.1 The only app that ive seen with noticeable lag was titanium backup, but other than that its been great
Ive also used link2sd and that works extremely well also.

Obviously, not infinite, but on my ov I have about 180 mb for my data partition. Using the d2ext script with a 2 gb sd-ext partition means that I increase that by literally over 1000%. I have absolutely no stability problems with the scripts. Sometimes a particular rom won't boot with a particular script, but I've always been able to find at least one script that will play nice with any rom I've used.
I really liked link2sd when I started using it, but eventually running out of space again, and constantly having to link apps got old. The script will move ALL of your apps without you having to tell it what to do, and your apps will still "think" they are installed on the phone, so widgets will work fine.
thanks!!!!!
Thanks guys!!!
I m now using int2ext+ by cronmod ....works perfect!!!!
very stable and smooth...:good:

SD Card partitioning on MTD ROMs

Hi There
Can someone explain what he\she did to partition SD card, and make all apps get installed on it.
Please note :
1. I don't want to use Titanium backup for this usage. I don't have the paid version and I'm tired of doing this one app at a time.
2. I saw some guides on the net, but they were all for GB.
(partition the microSD on PC using minitool) -can we use ext4 on our MTD ROMs ? What is the 1st partition for ? and the 2nd ?
(install busybox and super user) - Is it still needed ? (MIUI for example has LBE as su).
(install Link2SD) - Is it always in memory ?
(reboot and put partitioned SD card)
(Define Link2SD)
3. I also saw swapper instructions but I can manage with 170MB free RAM memory I get after removing all unnecessary system apps, and I remember ppl saying then that it kills the SDCard very quickly.
If someone has a clear guide or instructions that he knows work, that will be nice.
Thanks in advance.
Step 1. Partition your SD card to have a sd-ext partition. This can definitely be ext2 or FAT16. Anything else depends on your kernel. Most of them do support ext3 and 4, but... start with something fairly basic.
Regarding recoveries:
TWRP has always failed for me on this, so I'd avoid that.
This may be doable in CWM. I've seen reference to that newer versions of CWM removed the partition option, so you might need to flash an ICS ROM with an older kernel, repartition, and then flash back to the one you want.
Also note that if you use CWM to repartition, your SD-card will be wiped. So do a backup first.
Step 2. Install Mounts2SD. Either from XDA or the Play Store. Even if you do take it from the Play Store to get update notifications, I highly suggest grabbing the recovery script from the XDA thread so that you can get back your shifted applications without needing to re-download and install M2SD, since it likes to be on internal which means... shifted off.
Step 3. Open Mounts2SD. Grant SU rights at whatever point it asks for it during step 3. Hit the menu button. Go to Application Settings. Install the Startup Script. Tell it to use the built-in busybox as well, so that you don't need to install anything or worry about it failing. Back out of the Application Settings.
Step 4. Press on the Wrench to go into the actual specific settings. I currently have forced Cache, 1% Storage Threshold, Applications are the only bit moved, the File System Check is on and using the Ext4 Driver, 128KB Deadline for Internal and 4096 with Deadline for External, and Safe Mode is disabled. But decide on what you want yourself, set it, go back to the Eye to see your current info.
Step 5. Reboot.
Step 6. Wait 1-30 minutes for it to finish moving all your stuff around.
Step 7. Unlock your phone, open Mounts2SD, and make sure everything looks pretty on that first 'Eye' info tab. If you like it then close Mounts2SD and keep going on your merry way. If you don't like it or you've done something like offload your data and now your phone is wretchedly slow, go to the Wrench, change your settings, go back to the Eye, and reboot again. Repeat until satisfied.
I thought it would be simplier.
A few more questions:
1. If I partition SD on PC, then I don't need any partitioning on recovery so it should work fine even on TWRP or advanced CWMs. Am I right?
2. Why do I need scripts for? Isn't the app enough?
3. Why should/could it possibly slow down my device? TB 'move to SD' for all doesn't slow my device what so ever.
4. How and where do I see what partition is used for what?
5. How much RAM does the app take?
6. Have you tried other apps link2sd or something CM has built in I think.?
Thanks.

New answers to new questions.
1. Skip step 1 if you've done it on your PC. I just suggested recovery as that's easy... if you've made your sd-ext partition on the PC, step 1 is done.
2. No clue on Link2SD. I use Mounts2SD instead since it lets me set things. It probably does the same thing though and sets a init.d script that gets run during startup.
3. True. For some reason though having all your data moved to sd-ext makes our phone go to a crawl. Same if you move off the dalvik.
4. That's in Mounts2SD. No clue how you can see if you're using Link2SD.
5. For Mounts2SD, none while it's being used, since it just runs as a startup script. The app is just to control the script.
6. Not successfully. I had tried 5 or 6 different apps back a year ago or so when I first started playing with sd-ext and Mounts2SD was the best and free, so... never looked back after that. Now you can also do some system-flag tweaking if you want to donate, but the sd-ext stuff is all free.
I was able to successfully partition SD and use mount2sd on 4.3 SlimBean.
however, it was rather slow.
CM 10.1 and CM10.2 by DJL. did not allow me to partition nor did they recognize SlimBean's partition even if I replaced them kernel (to NilTMT).
I'm currently using CM10.1 which is stable as a daily driver and manually swapping apps with TB, I hate it, but this is the best combination I've come so far.
I sold my wife's SGS4G and upgraded her to SGS3 and hopefully in a year I will do the same. it had its moments, but on the bottom line it's a pretty ****ty phone with its lack of internal mem...but hey, it drove so many of us to go deeper and deeper trying to understand and made us more tecnolgical and solution oriented.
Mounts2SD worked for me on CM10.1, so not sure why it failed for you. Ah well.
A few things I have found...
Yes, you can partition on Windows, but you're really asking for trouble. It's not too bad download Ubuntu or the like and you can boot off a USB stick without touching your Windows install.
The TeamAcid kernels that I know of handle ext2/3/4 file systems. All kinds of arguments as to which are better. I personally use ext4 and don't find it obviously "slow" for the way I use my phone.
That said, what the boot scripts (which are part of a flashed "kernel" for the SGS4G) actually do with a "special" partition is another story. In some cases the first stages of booting will look for special partitions and mount them in pre-configured places. For example, the second partition of the removable card might be mounted on /sd-ext/ in many CyanogenMod ROMs. Many (most?) SGS4G ROMs don't have these "special" mount rules defined.
Moving an app to SD using the "native" approach just moves the app and none of its data to the SD card. It won't for example, move 25 MB of mail from /data/data to your microSD
Moving an app to SD (or anywhere else) doesn't keep it from generating its classes in /data/dalvik-cache -- It isn't "free" to have an app on SD as far as internal storage goes, even if it doesn't write any data.
Moving an app to SD will absolutely slow down your boot time. It does it by creating a file that contains a file system that then gets read and mounted at boot time. You can watch the parade of them getting mounted using adb logcat. It can take a minute or two to mount them all. Once mounted, that double layer of file systems shouldn't slow you down too much, since it is basically a read-only kind of thing.
Scripts are required since you need to be able to "fake out" the operating system as to where things are stored for anything (except if you just use the native app to SD method). In most cases you need new partitions mounted before the Android part of the OS starts running.
Some scripts are more robust than others.
TitaniumBackup (paid version) has a way to move data to an external partition. It works like a charm for me (64 GB Sandisk UHS-1 / Class 10 microSD). It was very tweaky for me to get it to recognize the ext4 partition the first time. It can bulk-move app data to the partition. I don't know which, if any, of the other scripts move the data to an external partition.
On my phone, an ext4 file system can be significantly faster than the internal yaffs, especially for write. Alas, it usually seems to be read that is a killer for most things in an well-written app. On my phone, yaffs can be faster than ext4 for short reads. Who knows how this would play out in real-world usage.
Other things that TitaniumBackup can do that help free up internal storage, at least in the paid version, are:
Dalvik cache cleanup
Integrate system Dalvik cache into ROM
Integrate update into ROM
Convert to system app
I can confirm Link2SD works where Mount2SD fails, which is an ext3 partitioned sd-ext on AOKP. it doesn't get any simpler than that.
