I know Froyo has built in apps2sd that allows you to save part of an app on your sd and the rest is saved on your phone, which is great for stock phones who have only had the conventional internal storage available in the past. I really like the Froyo roms that are out and have been using them daily for a while now. Is anyone working on an apps2sd for Froyo roms that will accept a partitioned sd card? Is this even possible on Froyo? If not I'll just unpartition my class 6 card and use it again. I've already formatted it 3 times and I'm afraid I'll corrupt it if I do it too many times.

Developing a2sd for a ROM that already includes it would be redundant, yes? The question then becomes, "Do I want the benefits of froyo and not be able to partition my sd card, or stick with 2.1 and be able to partition the card?"

Yes. Cyanogen and the team at Cyanogen(mod) are currently working on this for Cyanogen(mod) 6.1. Their goal is to have Froyo play nicely with Linux ext4 partitions.
No one has successfully done this yet, and CM6.0 isn't even ready yet. But yes, so you know, this is being considered and worked on.

Yes, you want the benefits. Cyanogen is not working on this mod because "it would be easier to switch between Eclair and Froyo ROMs." The reason that team is working on it is because Linux ext4 partitions are faster and more efficient than FAT32 partitions. Thus, the phone's performance is increased when running both apps and cache from a Linux ext4 partition.
So, just for the sake of discussion, here's a tangent... What I'd like to see if a way to convert /system/data/ to Linux ext4! THAT would be nice. I read about a way to re-partition your vital systems files, internal cache, and internal data paritions so that the vital files are contained on a partition that is almost exact to the size needed to run those files, so that the cache is a relatively small size, and so that data is the remainder. This is great, because it eliminates the need for Apps2SD and unties the dependence of your phone from your SD card if you use a lot of app space. To get this as well as the cache folder (hell, let's do the vital system files to) into ext4 would be amazing and would greatly improve your phone's performance!
You just made my night.

total noob
pretty sure it's not the developers fault of tazzsensefroyobt. because for a while it was working great for me. ever sense i tried to use apps2sd on PlainJaneT2_V2.0. i keep having an error on tazzsensefroyobt saying sd card is not mounted.
used rom manager to format sd card. then trying to fix this reformated using windows
There is a reason for that - the method to get apps2sd on a 2.1 ROM like PlainJane has you create a second partition on your SD card,to create a location to hold the apps. Unfortunately, Froyo will not mount an SD card with more than one partition.
You'll have to do these things, I think:
- backup your SD card
- do a Nandroid+ext backup from PlainJane, in case you want to go back
- follow the steps to partition your SD card from before, but choose 0 bytes for both the ext2 and swap partition sizes. This will erase your SD card
- go into the USB-MS option from Recovery to copy files back over to your formatted SD Card.
- Now you can flash the Froyo ROM you want

That's correct. For some reason I think that there is one of the 2.2 ROMs that actually will mount an SD card with more than one partition, but I could be wrong about that, and I can't remember which one it is. But if a Froyo or Gingerbread ROM will not mount a perfectly good SD card with more than one partition? That's why - it has more than one partition.

Froyo and higher will work with multiple partitions; it's just not real easy. The trick is that the SD card has to be partitioned in a certain way.
From memory of the thread that's in the Dev section (I think the OP was Conap), the first partition has to be FAT32, and would have to be large enough for any NANDs and ROMs you want to ever backup/restore and flash.
Any other partitions can be anything you want BUT with this one rule. If you have a total of four partitions or less, then the last partition HAS to be FAT32, and will be the partition that'll be mounted by the AndroidOS when it's up and running. The second part of this rule is that if you have MORE than four partitions then the fourth partition is the one that has to be FAT32.
Just like partitions 2 and 3, anything from 5 and on can be anything you want. Conap also developed scripts to mount partitions like the first FAT32 one, since it's nice to have access to it from the running phone from time to time (mounting it through USB from Amon RA or Clockwork Mod should still work as normal). I think he also made ways to mount these other partitions from Windows. My memory is fuzzy. I only tried once to make this work for me, but I wasn't really successful mounting the oddball partitions to the phone or to Windows, and I didn't try real hard - I didn't care enough to really try to figure out what I assumed I did wrong, since I believe other people were able to test it just fine.
This theory of operation appeared to be developed in conjunction with the dual-boot AndroidOS 2.1/2.2 ROM by TeamAndIRC (I think they're called), which includes Conap and others as members. I never tried the ROM.
I'm not positive if the limitation of the partitioning applies to all phones with 2.2 or higher, though. I've read some threads for other phones that officially ran 2.2 in which they mention partitioning to be able to use old style Apps2SD instead of the native one, and there wasn't any mention of any complicated partitioning scheme.
Does anyone know enough off the top of their head to verify this?
So I'm currently running Ginger Tazz 12 and I want to run all my apps from my SD with a partition but when i do my phone says I have an unsupported or blank sd until I delete the patition.

Froyo (2.2) and beyond, at least on our phones, do not like the old style Apps2SD partition except if it's located in a very specific way. If you ask me, it's a PITA and therefore I prefer to use Froyo and beyond's native Apps2SD ability, which doesn't require multiple partitions.
If you want to try that way, make a backup of your SD card, partition the SD card with no Ext2 or Swap partition, and all the remaining space as FAT32.
Then (assuming a Cyanogen-based ROM) in the Cyanogen settings enable Application moving and set the default location as you wish (sounds like External).
Apps to assist in using Froyo+ native Apps2SD ability:
"Install Manager for root users"
"Apps2SD Pro"
Titanium Backup (paid) will allow you to en mass move apps to and from the SD card, also it has the option to restore backups of apps back to the location they were in when they were backed up from another ROM.
Also note that with Froyo+ native Apps2SD, you can't move apps with widgets you want to use on your homescreen to the SD card. The widgets won't be available in the widget list until you move them back to the internal memory.
If you remain firm that you want to use the old style Apps2SD, I am no expert, but Conap has outlined how to configure it so it will work under Froyo+. There's a thread in development, but you'll have to search for it. It's more complicated to have access to the FAT32 partitions (you would have to have at least two in this case) under both the phone and Windows. To clarify, exactly one of the FAT32 partitions will be naturally accessible from either the phone or from Windows, but they'll each access the opposite FAT32 partition. You have to take extra steps under both the phone and Windows in order to access the "other" (not normally visible) FAT32 partition.
Like I said, personally I think it's too much a PITA for me, but you're taste might be different.
Well over all it just runs all the apps from SD and it still saves memory. I have Ubuntu so any partion is easy I just need the steps

Hi Guys,
I would have tacked this onto the back of an existing thread, but the only relevant ones I could find were in development (I’m still under 10 posts) – and this is more of a general usage question anyway.
I’m running CM7.0.2 and been I’ve been using Apps2SD (darktremor) for a month or so. The onboard memory for apps on the Legend is abysmal, so freeing space up and being able to have more than half a dozen apps is great. I was looking to take up Data2ext too. I’m still S-ON (I haven’t found a serious need for S-OFF yet, and I figure the less access I have to the bowels of my phone, the less likely I’m gonna brick it), so still using CWM2.x and obviously not running EXT4 yet.
Just wanted to ask a couple of stupid n00b questions before I try anything (I’d rather ask this now, then be posting “help I ****ed up my phone” later on).
- Am I right in believing that that data2ext only moves app data, not the apps themselves to the SD car so I need to continue using apps2sd as a companion script?
- Does data2ext need its own additional partition setting up prior – or does it create its own partition/utilize an existing partition? If there needs to be a preconfigured partition, any recommendations on how much space to allocate?
- Is there anything in particular that I need to know before I run through TGF’s guide (http://forum.xda-developers.com/showthread.php?t=902395)?
Thanks for the help guys!
data2ext will use the partition that darktremor currently uses, and you don't want to have dark tremor and data2ext on at the same time, funny things happen.
Data2ext remounts the entire data partition to a partition on the SD card. So anything that gets written to /data (apps, app data etc) goes to the SD card instead.
You need to know that this could go wrong, but I think the first post covers most of it.
That makes sense. I previously wasn’t sure if data2ext only moved app data only, and apps2sd still needed to be used to move the actual apps themselves. As that’s not the case, it’ll make things much easier not having to **** around with 2 different scripts to hopefully get them to play nicely.
I did actually end up stepping up to Blayo’s fake-flash CWM 3.0.1.3 yesterday; though I’m still trying to work out partitions/file systems with it – creating partitions in CWM recovery defaults to EXT3 with no option to set EXT4, and after manually creating an EXT4 partition in GParted CWM wouldn’t let me mount /sd-ext. As your initial post already details formatting /sd-ext to EXT4 anyway, it’ll be interesting to see how nicely this plays with 3.0.1.3.
Thanks for the disclaimer on the risks involved. Without intending to sound patronising; I’m well aware there is the ever present potential to really **** things up, and that I do only have limited knowledge compared to a lot of people posting on xda – which is why I try and get any/all information available before hand, and follow instructions given closely.
Coo'. Just shout if you need help, I'm subscribed to this thread so I should see it
Seems to have worked like a charm.
One question though – I know you can confirm data2ext is successfully running by launching "data2ext --enable" a second time after the final reboot, but is there any means to monitor the used/available space on /sd-ext?
Both Titanium Backup and a2sdGUI allowed me to keep tabs on this, but Ti is unable to see the /sd-ext partition now (I haven’t bothered installing a2sdGUI, not really any point).
It might be a small thing, but if possible I would like to be able to see it fill up, just to give me piece of mind all is OK.
*edit* scratch that last part, just noticed Android and Ti now sees the Internal Memory as a total combined capacity the internal memory + /sd-ext. Eitherway, I'm up and running

Hi,
Since this is a noob thread I'm feeling free to ask for help.
Somehow without any knowledge I've managed to Root my Legend, Flash roms numerous times, make my Legend S-Off, twig and play with different options like splash screen and all sorts of stuff that you need a bit or more of development knowledge. I'm a psychologist - I have no knowledge whatsoever.
Now that I've flashed ogo2's rom found here - http://forum.xda-developers.com/showthread.php?t=987251, I have cut down internal space to about 20MB+-.
I need help with this whole data2ext, ext2/ext4 and all the commands I've never met in earlier development stuff I've done to my Legend.
Where do I start? Is there anywhere I can read a noob guide for these issues?
Please help!

Hi TGF,
I need help mainly with setting it up. I have no intention learning developing through trying here and there to implement different things others created.
My intention was to use the data2ext you created.
At the moment I've changed back to the nightly builds of CM7 (currently #153), since I had sync problems with ogo2's ROM. So I'm not so pressured space wise, but I'll still be glad to go through with the Data2ext.
Thanx,

You do need to backup your sd card, our you lose all your data. Rom manager has an option for creating ext partitions on your sd card, and I'd go for ext4, as it's safer. There's a section in that thread on upgrading from the ext2 version. Create your position with rom manager, then follow that section through. The commands can be executed on the phone using a terminal emulator, or from the pc using adb.

Hi guys,
This question is bouncing on my mind for some time...
Many people state that they use darktremor a2sd on Cyanogenmod, and I'm wondering why?
Darktremor's objective is to move apps to SD, right?
Well, Cyanogenmod also allows us to do the same, right again?
Sooooo, why use darktremor on Cyanogenmod?
Thanks in advance
I'm also wondering about the difference if I was to use darktremor's script. I noticed the default Apps2SD would not completely transfer the app to the sd card (for example, if I transferred a 20mb game, it's reported that around 1mb is still left in the internal memory), hence the amount of apps I could install on my ace is very limited. Would using darktremor's script solve this?
Apps2SD (the one in Froyo and CM) moves most or some (depending one the application) data under /sdcard/.android_secure and /sdcard/Android/.
It'll leave behind some files in the internal memory.
A2SD (and S2E and Link2SD) moves the ENTIRE application (app files, data files, dalvik-cache) to a separate partition on the SD Card, then links the apks to the filesystem (linking is Linux term for making a shortcut).
Another advantage of this is the bugs present in native apps2sd -- such as widgets not appearing after a reboot -- are not present in a2sd method. This is because of a mount script executed during the booting process.
This post was sent from hell.
scripts like dt a2sd tricks/fools the android to use sd-ext partition as an internal memory...
that's why when you use apps2sd(one that you can use from the app info menu) just moves a little part of the app to sd card while scripts like a2sd moves the whole data to the ext partition..
But I have to create a partition before I flash dt or link2sd? Or it is a virtual partition that the program creates? Is it really worth to use dt or link2sd?
Sent from my GT-S5830 using Tapatalk
Yes, you need to create a partition on your SD card (512MB is more than enough). The easiest way is to just partition through CWM Recovery (under Advanced, I think). It'll automatically create an ext3 partition of your choice size (also swap, if you want swapspace).
Don't be deterred by ext3 because it's lower than ext4; it's actually much more stable.
Is it worth it? Very, if you know what you're doing. As long as you don't mess around with the partition, say when you plug in USB mass storage mode to the computer, it should be fine.
My ace never appears on my cpu as a drive. Dunno what is the prob.
Anyway... how do I format my sd after it is partioned? To delete the partition ..

Darktremor's a2sd and CM kernel...
I've had some damage to my phone. More details over at my post in General questions.
My damaged unit. SK17i My consideration for replacement. MK16i. From Xperia Mini Pro to Xperia Pro. (For the price difference, it seems for the hardware upgrade to get the bigger unit.)
My basic setup? Custom Kernel with root and a2sd.
Problem. There seems no Custom Kernel but one... bbooff's. (Waiting to here if it also will support the a2sd of darktremor.)
I came across CM being available already for the MK16i.
Problem. I just use root & a2sd. Suites my simple needs. I don't do Custom Roms at present. My need is for a stable communication device.
When I got my SK17i. I read that there was a clash between CM and a2sd. Has this then been cleared up? (Fully? For those CM users who may know. I'm a noob to Android.)
Is it possible, from instructions I read on getting CM on the MK16i there's a CM kernel that must be installed 1st, to just use the CM kernel and Stock Rom?
I am just thinking maybe there will be some clash here? Then maybe not? I know the forum instructions did clearly say stock Kernel is incompatible with CM. That may be about some features CM wants to use. Stock Rom simply may not access any 'bonus' features of CM Rom but will there be a problem otherwise?
Anyone who knows more about Android... maybe have an idea?
My setup and use is pretty basic, pretty simple and no, I do not want those apps2sd programs that don't use an Ext partition and don't 'fool' the system into thinking it's running the programs on the system partition.
Well, looking for information. I would rather get the MK16i. Nice bit of kit, but I also firmly want the same basic little setup I've got here but there seems at the moment to be few Custom Kernel's for this device and I am not even about to try to roll my own. Wouldn't know where to begin.
First of all i am not a dev, and the statements bellow are confirmed by devs and known guys from our O1 community like Maktail and Miasmic (thanks guys).
Most of us use a2sd scripts like darktremmor, ungaze, link2sd etc. and many of those are suppose to provide us with practically unlimited sd space for apps and data. But the common problem which allways occures is that after moving one too much apps to sd you will get at some point bootloops. The phone will not be able to load all apps from sdext partition and reboots all the time. So no a2sd script is able to provide what is ment for.
My question of why use a2sd script is related to the fact that moving apps to sd using built in android script which resides in every ROM (even stock obviously), moves to sd the same amount of apps as other scripts mentioned and has the same behaviour of bootlooping when too many apps are moved to sd. The only difference is that other scripts provide more options, like moving dalvikcache to sd. But that doesn`t help either.
So why use a2sd scripts when the result is the same as using stock android script?
A2sd dev dk_zero-cool (thanks) said here http://forum.xda-developers.com/showthread.php?t=1342387&page=25 that is common knoledge that android cannot handle more than 1GB external data and recommended to use no more than 1,5 GB sdext partition formated with other recovery than CWM which is buggy. Did that and results are the same bootloops. Which means that moving too many apps to sd gives at some point system instability no matter what app or which script we use.
That is why more exepensive phones have more internal mem, up to 16GB in nexus case for example, which is using internal mem even for data games storrage. In that case they use a script to link internal sd data to external sd data (folder mounting), which is of no use for us.
Using DT, ungaze and android built in move to sd option, i could move to sd the same amount of apps before getting bootloops. So why buther using all king of scripts when the resilt is the same?
And now i get to the real questions, which are:
Is there any a2sd script that gives the use of more than 1.5 GB of external data without system instability (bootloops)? (i could move about 1.2 GB to sdext using ungaze) Please post the answer to this after you tested and moved or linked to sd more than 1.5 GB of apps.
Is there a 1 or 1.5 GB limit of external data which android (Linux) can handle before getting instable? If so, can this limit be overcome?
If there is a limit, why the options to create more than 2 GB sdext partitions in recoveries?
Can some nice dev make a script that lets the phone give us a slap on the face when getting close to the point where the system gets instable, if the limit of external space cannot be overcome? It seems that most of a2sd script devs discontinued their work.
my opinion
I have used both ungaze and link2sd... link2sd got unstable when i am using almost over a gig of Ext partition while right now I'm using ungaze with 1.7gb of used Ext partition... It was stable for me... No bootloop or anything...

yes but it makes sense if your internal sd card is only class 2 (imagine factory want to cut budget product and add low sd card read & write).
one thing for sure, my quadrant says about 800 using internal sd card, and now about 2000 using eksternal. and if someone say that quadrant score is irrelevant, i only ask, why?
I use link2sd with 512 or 600-700 MB EXT3, and never got a problem, I prefer huge apps/games like NFS shift, in internal memory and data obviously in normal SD partition, and I prefer keeping apps like facebook, camera360 and other [unmoveable by default] apps in EXT3.. this way I can install several apps without any problem
I dont know if this has been asked before and I am feeling lazy to search. Does ungaze data2sd work with ext4 now?
