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
i no my question is noob but still.....i m using CM7 nd CWM 2.5.0.7....if i use d optioned partition ur sd card....is dat data to ext ? ndnd wat is swap size ? also how to check what claSS SDCARD I HAVE... I HAVE 16GB KINGSTON SDCARD!
I've a noob question too, if the sd card is partitioned to allow some internal apps to run on this special partition what is currently the safest procedure to do this?

I got mine up and running last night... created a 1 gig partition for data... data2ext is active, but my phone is now SLOW as molasses. SD card is Class 10 and tests on a computer reveal it to be fast.
I'm at a loss.

The card probably doesn't handle small files very well. Class 4 seems to be the best bet for data2ext
You're kidding. Ugh! Maybe it was the method I used to format?

Seriously?
So are you using a class 4 with your own cm data2ext script and in ext2 or ext4?
Serious.. It is mentioned several times before by Blay0. Even a fast card will work very slow with data2ext. Why do you even need data2ext? Are you a developed? If not app2ad should beer enough for you... NInge really needs data to be on as i they are not often changing system files..

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!
reupugi
edit: Oh I forgot - I have 8 GB class 4 card.
What help do you need? Understanding what it is and how it works? Or just setting it up.
Are you planning on using the data2ext found in my thread, or somewhere else?
Sent from my Legend using XDA App
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,
reupugi
Ok, well the guide in the first post covers most of it, is there a specific bit you're stuck on?

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 all.
First of all, I apologize if my post already exist.
I have a prob with my sd card that can't be recognized with the achtojan ROM downloaded from this post http://forum.xda-developers.com/showthread.php?t=1151933.
My sd card is configured to be using with link2sd (2 partitions, one with FAT32 that have almost all my datas and applications saved in it , and the other in ext2).
The question is, what can I do to make my sd card recognized with both FAT32 and ext2 because I wanna to use link2sd again, whether with this ROM or with any other ROM having this prob.
Thanks for your precious help.

Thanks for reply, but, the prob in the post you suggested to me isn't the same. And I won't format my sd card, because I've a lot of things in it, and it will be a hard work to copy all in my pc, and before all, I wanna to use link2sd with the ROM I use, whether if it will be the achtojan ROM or any other.

Use mini tool data recovery this will repair your card without losing data, can be found here it's free for home users.
http://www.powerdatarecovery.com/
This might sound obvious but next time backup your sd card first before partitioning, even though it says it wont interfere with your data. I had the same problem but luckily i had a backup.
I think that you did not well understood my problem. The fact is that my sd card already works on another ROM without any issue, it has just to be detected with the ROM that I use at present, here it is.

Look buddy i gave you the link and the answer you are looking for in my first post to you, do some searching and reading, here is the post in that thread that solves your issue.
http://forum.xda-developers.com/showpost.php?p=15824115&postcount=12
also it applies to the same rom you are using.
Look dude, I saw you that there are big big big differences between the problem in the post you suggested to me and my problem. First : I have in my sd card 2 partitions (one in FAT32 with lot of datas and the other one in EXT2 for use of link2sd) and the sd card have to be detected, but the poste have just a problem with formatting his sd card. Second : my sd card already work with another ROM with no issue, if I reflash to the other ROM, it will certainly work with no prob of detecting. Third : I wanna to rest with the ROM I've flashed actually (I mean Achtojan's ROM) and fixing this issue if somebody can help without formatting the sd. That's all.
Thanks for your tries to help, but it seems that you don't understood my request the first time, then you tryed with something useless in our case. Anyway, Thanks for your tries again.
Why don't you just copy all your data to your pc, delete your partition, restore your data and then use the rom you want, why have you issue in formatting your sdcard?

It is a known issue for ALL custom ROMs.
They actually mount the 2nd partition of the SD -if there are more than 1.
Being an ext2, it's not recognised by the system as storage space.
So if you want to use a custom ROM, Link2sd is a NO-GO.
You need to reformat your SD into a single FAT32 partition. That's the way it is.
Also, I have wrote this exact same post more than 10 times. So, the question has already been asked. Using Search is not always easy but it pays off eventually. Please make the effort next time.

This is a general problem in EVERY 2.2+ ROM for X10
My guess is that the new vold (known also as "vold2") that manages the storage devices is not properly configured.
My_Immortal and me were the ones who tried to find an actual cure for the root of the problem, but both of us ended up PMing the devs
Try to write a nice message to Zdzihu, Jerpelea or even DoomLord(that guy surely has some knowledge as well) and cross your fingers
Till it's not fixed try to stay on 2.1 as the new Gingerbread update is on its way... hopefully.
oops, someone was faster than me... or I was just polite to let the girls be the first
i will again say what everyone else has said before.
link2sd has problems with custom rom's so far.
check my sig for details on how you can have multiple partitions and still get your card detected in custom ROMs
however basic problem is X10 checks the last partition (should be vfat) mounts it as /sdcard
link2sd takes /sdcard partition number and add's a 1 to it to get ext2 partition. (which could not exist)
on top of that xrec will take first partition as /sdcard when you boot to sdcard.
so thats a mess as of now.
i tried vold and other stuff also all in vain even tried contacting the dev behind link2sd asknig him to add a option to select partion but no reply so far.
hope this helps in solving your query.
In the droid forums, there are a thread that speak about this problem too, and many people searching solution managed something to make sd card detecting, but I am not very advanced in the subject, thus I cannot say about it more. Maybe that some of you who know a little more in the subject can find something useful for us there.

ohk sorry to OP first i am hijacking this thread
@Doom, just thinking out loud.
I don't have required tools till next 3-4 hrs
i just need to check how link2sd is mapping (once again last exercise was month back so forgot all of it.)
we can see what volume label he is using to mount the partition and can use hw_config.sh or a new file say /system/etc/init.d/99sd_ext2.sh just about anyname till it has 99 in front making it last item to run.
and add code to mount the partition we want to be mounted in our predefined location that should make it work.
Hope that can work. but will need to check and same as i did last time i will again have to go 3 partitions way.

No problem mate, take your ease. It can help a lot of people.
I've read little in the thread, but as I said it, I am not really very advanced in the subject, and I can make nothing . I can just say to you that with a buddy and the help of this subject, and after a lot of tries, we were able to make his sd card detectable on his phone (an HTC mytouch 3G slide), but I don't rememeber what we have done, and the solution was just temporary. In rebooting the phone, it was necessary to do all again from the beginning, which we were not able to make due to our limited knowledge .
As now, I hope that you or any other person can make anything useful for all people around here.
Thanks for your efforts.
PS : I've temporary returned to EWJET ROM that is already configured for use with a sd card parted. Maybe Erickwill can help too. Good Luck.
ohk a quick check
if something is mounted on /data/sdext2 then link2sd thinks it has found the second partition
what i did was
1) created a temporary img file 100 MB
2) did a loopmount of img file on /data/sdext2 folder
3) link2sd working.
(I know i am lazy i don't want to format my card just wanted to help all as much as i can.)
now this was test so what we are missing here
1) we need a way to automatically mount a pertition on /data/sdext2
2) we will still need 3 partition on sdcard as my last experiment was to check the same and we if want to use ext2 we need
vfat-ext2-vfat to the minimum.
last being your sdcard
first being your recovery sdcard
and ext2 partition used by link2sd
3) tried hw_config.sh as suggested by DooMLorD
even checked /system/etc/init.d/
they all seem to be executing well before sdcard gets mounted or not at all.
so this is where i am stuck and right now out of time need to focus on other tasks.
hope someone can find a way around to this.
NOTE : EWJET ROM are 2.1 rom if i am not wrong. 2.1 roms do support link2sd as of now its basically the problem of 2.2 roms.
I will try your method with the three partition, but I have a question, how to make the third partition detected in windows for copying all my datas in it.
The method with three partitions don't work too. I'm really confused now.

How to Move apps from Phone memory to SD in Android 2.1
in Xperia X10
My phone is rooted.
any help????
Your options would be scripts like DarkTremor or (the slightly more user-friendly) Link2SD.
But be warned: both are not 100% stable... I've finally removed DarkTremor after a lot of issues: How about upgrading to a custom ROM instead?
Hi.
I dont want to start new topic so I use this one to describe my problem.
I read a lot of webs to find solution but here's comes some problems with that.
I've got Samsung Gio S5560 and 4GB SD card. After creating 2 primary partitions FAT32 and ext2 link2sd says that "no space left on device" and i cannot do anything. Even when I use 2GB card or create partition f.e. ext3 it doesn't works.
Can anyone help with that ?
Sorry for my english. I hope is understandable
Of course phone had been rooted.
Android 2.2.1
Regards.
I'm not sure how these scripts determine which partition to use... have you tried partitioning through ClockworkRecovery? Maybe they need the partitions in a certain order or (more likely) some other requirement. CR would very likely take any such requirements into account.
P.S. Your English sounds fine to me, but this doesn't come from a native speaker either, so...
I used to create partitions MiniTool Partition Wizard Home Edition. On YT there ale some tutorials so I used them. At the beginning I create FAT32 and then ext2. Maybe at the morning I try some new configs with my SD card.
I setup cm10.1 nightly on my fascinate and originally had ext2 + fat32 partitions. I was running into memory issues, so I went ahead and created a swap partition and was attempting to enable it. I probably found old/bad instructions and my phone lost a lot of programs. I would like to reset the phone with better partitioning and get the swap working properly. I read that CM can enable swap without installing any additional programs. Can someone walk me through the best way to setup swap. Also recommend sizes for my partitions. I presume fat32 will be the biggest followed by ext2 or should I go with ext3? then how large should I make the swap? Thank you for any help you can give me.

Hello guys,
I'm so sorry if this is not the place to post this, but I am very new around here and don't know exactly how things work.
Now. I am an Android user, but I am not an experienced one. I rooted my phone a while ago and started using LinkSD (I only used freeze feature) and today I decided I should link some apps so that I can clear up some space in my internal memory.
I followed a guide and partitioned my SD Card (FAT32 and Ext2 if that matters) then started linking the apps. However, I keep getting an error while doing this. I can easily link application files and library files, but whatever I do, I cannot link the dalvik-cache files. It keeps telling me: "Failure rm failed for /data/sdext/dalvik-cache/*com.anddoes.launcher*@classes.dex, I/O error"
As you can guess, the /.../ part changes with every app. I chose Ext4 (Ext2 didn't work) after I partitioned my sd card and opened Link2SD. Could this be relevant? Should I do the partition again and chose Ext4 instead of Ext2, would it help?
Thanks in advance!

I just solved the problem using the link you gave me. As I suspected, choosing Ext4 while partitioning the card as Ext2 was the problem and it's solved now.
