Clone SD card (with a2sd on)?

Question:
I've noticed I'm pretty much at my limit for space on my current SD card (like 80MB remaining on a 4GB!)...
I've ordered an 8GB card to replace this one... but how can I "clone" my current 4GB card (with a2sd partitions) and then copy it over to my 8GB card, without losing data, settings, apps, etc? Is there a way?
Thanks in advance.

Do this all from within Clockwork Recovery:
1) Make a nandroid backup
2) Connect the phone to a computer
3) Partitions menu > mount USB storage
4) Copy all contents from the old SD card to a temporary folder on your computer (including the clockworkmod folder which contains the nandroid backup you just took)
5) Unmount and disconnect from computer.
6) Pull battery to shut the phone off, or if you would prefer you can boot the phone and then turn the phone off immediately afterward. Pulling battery just saves time.
7) Put new SD card in
8) Boot into clockwork
9) Format the card with Clockwork w/ ext partition
10) Connect to computer, mount USB storage again, copy all files back to the phone
11) Unmount and disconnect cable from computer
12) Nandroid > advanced restore > Restore sd-ext only
13) Reboot and you're done.
And if something goes wrong, it's not really a big deal since you will still have the original files on the old SD card so you can try again or ask for help to try another method.

Sounds complicated enough to work. I'll try when the card comes and let you all know. Thanks!

Haha yeah, I think it's the easiest way to do it with Windows, since you can't read the ext partition from the computer. You could probably just copy the contents of both partitions through Linux if you're comfortable doing that.

Doesn't a nandroid backup the ext partition too?
If you're using windows you could just backup your fat32 partition on your PC and partition your new card and then copy all your files back and do your nandroid restore.
I think this would work...

Clockwork does not back up my ext partition. It can't mount it or anything. Not sure why. Might be because its ext4, but when I do nandroids the sd-ext backup always fails.
I have to use Ubuntu and mount as storage. Then both of my partitions mount on my computer and I can do as I please. For me this seems easiest anyway. Simple copy and paste and it can be done from a live cd for those that dont already have Ubuntu.

What version has that menu option? I don't see it.

Interesting. I was sure you could format a card with ext partition through Clockwork but apparently you can't. You can do it through ROM Manager though, so I guess you may have to boot into the phone to get to it.
The programs on the ext partition won't show up yet of course. Don't be alarmed. Just partition the card through ROM Manager, then once you're done doing that, do the nadroid advanced restore. If there are any problems after a reboot (i.e., it didn't work correctly), go back and try doing the regular full nandroid restore.

v2.5.0.1
This doesnt create a partition though. It just formats an existing partition. You'll have to use drumist's method of going through Rom manager to actually create the ext3 parition from the phone.

Tried running ROM Manager - of course, it's installed on the 4GB card which isn't on my phone when I have the 8GB in to format. So then I re-installed it using the APK... but I get the exclamation mark when it boots to recovery to format... probably because a2sd is installing the same program on the ext part which it is now trying to format.
I think I'm going to have to format/partition it using Linux somehow instead, no?

someone recommended in another thread that when that happens you just pull out the battery and then use volume down+power to boot back into recovery and it should then work.
But the method I use is to do it from Ubuntu (a linux version). If you dont want to install Ubuntu on your computer you can make a bootable CD or USB drive with Ubuntu on it (directions for this are on the Ubuntu download page) and actually run Ubuntu from the CD/USB without ever installing it on your computer. From there you can use gParted to create paritions. And while I recommend making backups, gparted even allows you to resize and move partitions without deleting anything.

Yeah, that's what I was worried about. My suggestion then is to format the card through linux if you have a SD card reader. Easiest way is to use an Ubuntu LiveCD. Do you know how to do this on your own?
Also, definitely do a full nandroid restore once the SD card is reformatted. Since you booted the phone and tried to install an app, it's possible something got screwed up -- nothing to worry about though because a full nandroid restore should revert everything.

I'm reverting back now, going to sleep on it, and then investigate formatting it via LiveCD tomorrow morning. It's been several years since I've had to go near anything Unix.

By the way, another option is to just do a clean install on your phone with a ROM that has ROM Manager built in. Use that to do the format on the SD card.

That got me thinking...Ive never had a problem adding an ext partition using Rom Manager. Ive done it to 3 SD cards now without a single issue. BUT, Ive also always done it while on cm6/7 which both came with Rom Manager pre-installed with the rom and quite a bit of integration with the rom manager app...just a thought...
EDIT: Scratch that, I used it for 2 SD cards, the 3rd was done with Ubuntu.

Here's my post from the other thread
jdwhite87 said:
Rom manager - partition SD card - choose your partitions. It will reboot into recovery and try but fail to partition your card. Pull battery. Replace battery - hold volume down and power. Wait for it to try and find the libde. Img then press volume down and it will highlight recovery then press power. It will boot into recovery and finish partitioning your card.
I think that's how I got it to work.

I did this with two different SD cards on fr008. Both were sandisks. One was a 16 gb class 4 and the other was an 8 gb class 6. I couldn't get gparted to partition the 8 gb for whatever reason. I didn't know what Ubuntu was when I partitioned the 16 gb

It seems like an oversight that maybe of the masses of people with Android devices that one day the general (non-xda) population would want a simple way to transfer their sd card data to a larger card...
I Imagine there are a bunch of people out there clueless.
Hell, I read XDA and there was still no clear simple way in this thread.
(I got here from a Google search for SD CARD CLONE)

Got it to work, finally. Required some back-and-forth with the Nandroid backups, but I have everything running off of my 8GB SD card now, without reinstalling!
Now, to sell off my 4GB card... anyone?

link2sd

installed link2d on stockrom after root with universal androot and formatted the second partition with fat32 since it doesn't support extX partitions.
Everything works.
link2sd asks what to link: app, dalvik-cache and library
Maybe must play with these settings to have WIDGETS still working when linked ?
I remember they usually stop working when installed on sd...
this omap is really fast !!!
with flash working great too !

I've used it just for games and a few things that are bulky like opera. I didn't try and widgets/livewallpapers because of the time spent preparing the SD card on startup.
It's so much easier using this when you don't have to worry about apps eating up all of your available storage.

I use it with almost everything. Only things that I'd like to have available when things go wrong and I have to boot without the card, I leave unlinked.
BTW. I'm using a kernel driver that was in the app2card .apk file to allow be to mount the partition as ext2 instead of fat32

A good thread on how to re-partition the SD card

I'd be interested in finding out what you did to get app2card working....
I used it to partition the sd card fine (well when i finally managed to click the done button... grr...) and it copied apps to the same partition but it won't mount the partition and has kept the apps in the main memory too...
is there better apps or a way to do it that's easier?
does the flipout support ext2?
I love this phone to bits already but it's a major let down when you can only get a few apps on it with it being full and having a fit!!

Meh.... tried link2sd... now my home button doesn't work and nothing will download from the market...

maybe you have used a rom without root permission. make sure that your rom supports app2sd. Secondly partition your sd card with the help of gparted livecd or you can use the AD recovery's build-in tools to partition your sd card. then flash a rom supporting app2sd. here cm7 recommded,the extra space will be recognized automatically. if you use miui rom, pls make sure that your partition format is ext3. after flashing miui, open terminal-1.su-2.a2sd reinstall-3.reboot automatically-4.open terminal again-5.su-6.a2sd zipalign-7.a2sd cachesd-8.reboot automatically-9.just install whatever you want.

This makes me believe that App2sd+ is working, how else is there only 22 mb free? What is the partition size you made?
Things you can do:
Clear Cache of apps
Clear the downloadfile-#.apk in /Cache/ (you need a root explorer to do this)
Backup apps, delete apps, restore apps.
Another thing to do is to start from scratch, reflash your rom, using a backup program to backup your apps. Completly clear caches, and wipe sd card.
DOING THIS WILL WIPE YOUR PHONE AND LOSE ALL SETTINGS
Rommanager is only available for cLK, make sure you have cLK, or phone will boot-loop.

Guide to partition SD card and use with Link2SD to store apps

I have been looking for something like this for a while. The flipout lacks internal memory and it soon becomes a problem if you want to have a good set of apps.
Here's what you'll need:
1. Rooted Flipout (I won't post instructions to this step, look for "Universal AndRoot")
2. Partitioned SD card (see below for instructions), depending on the method, you might need a phone with CWM to do this and ADB installed on your PC.
3. Download Link2SD from Market
So here are the steps:
1. Partition your SD card. There are many ways to do it. I will post two ways:
Use MiniTool Partition Wizard Home Edition
My PC didn't like this tool and I wasn't able to use it. However, it should be quite easy, you just need to put your card in a card reader and build two partitions with the following characteristic:
First partition will be your main card partition, should be of the whole card size minus the extended partition you want to create
Second partition should also be fat32 (link2sd didn't like ext2 nor ext3 on the flipout, it only worked with fat32)
Use CWM. I personally didn't want to install it on the Flipout, so I used a Samsung Epic 4G for the steps. You should be able to use any phone with CWM to do it, put your SD card in the phone with CWM and boot into recovery:
adb shell reboot recovery
parted /dev/block/mmcblk0 (open partition manager for SD card)
print (prints partition table)
Here you should have one partition table, starting at some point and ending at some point like 7969 if your card has 8GB. Take note of the End value as you'll need it.
rm 1 (deletes partition 1, this will erase all data on the SD card)
mkpartfs primary fat32 0 7425 (creates a new primary partition, the second number should be the value you took note of in the last step minus the size in MB of your desired extended partition).
mkpartfs primary fat32 7425 7937 (creates the new partition for applications, starting at the end of the last partition and ending on the max size of the card. In this case I used fat32 as I couldn't do it with ext3 nor ext2, link2sd didn't like this format on the flipout for some reason).
The partitions are created and you should be able to go to the next step.
3. Reboot your flipout with the partitioned SD card, make sure to have link2sd installed.
4. Open link2sd, it will take a while, ask for root permissions (always accept and make sure to have Remember checked).
5. It will ask for the partition type, select fat32. If you are asked to reboot your phone you have everything setup, otherway please post your problem.
6. Once rebooted, open link2sd again and go to settings and configure. I don't like having all applications automatically linked as widgets and this kind of apps can fail if they are on the SD, so I have this setting unchecked. However this is a personal decision.
7. To move an app to the card, hold your finger on it and when the menu appears, press link and confirm.
8. To move an app from the card to the phone, hold on it and press unlink, check everything and wait for the app to be returned.
Further Tips:
Avoid moving apps to the SD that are use widgets or that run all the time like: messenger apps, alarm clocks, climate widgets, etc. I tried one or two without any failure but I feel they could be less reliable this way.
Don't remove your SD card if the phone is turned on, now it has a partition that is used by the system, if you remove it you could have issues, I would only remove the card with the phone turned off completely and not boot without the card.
I made some tests connecting the USB cable to the PC and using the phone in storage mode, the PC could see the primary SD card partition and the phone could still work with apps on the second partition, so it seems to be stable in this sense.
If you need to switch to another card, you would have to setup the new card in the same way; I don't know yet if backing up the second partition and restoring it to the new card will work. If your data is critical use some SW like Titanium backup to back up the apps that are linked, remove them completely and restore when you have the new card setup.
So, this has worked for me like a charm, the phone really seems stable and I have so far like 150MB of apps on the SD card. No need to have a newer Android version, it seems very stable.
Disclaimer:
Any process that involves rooting your phone and partitioning can potentially cause data loss and/or bricking your phone. Do this only if you are 100% sure of what you're doing, I will take no responsibility for any data loss / damage caused by this process.
If you have any questions I will be glad to help.

Hi great post above
I rooted my phone and I partitioned my sd card into 2 partitions , both FAT32 primary 3.7GB and when i open link2sd and select either ext 2 or ext 3 I get an error message
"Mount scrip error
Mount scripe cannot be created.
mount: no such device
ext 2 may not be supported on your device. Try FAt32 on the second partition"
Has anyone come accross this problem before ?

Hi,
When you open link2sd,scroll down and select fat32. I tried formatting the second partition with ext2 and ext3 wit no luck. Fat32 is working just fine.
Regards

Hi Thanks a million that worked great

thanks
hi i tried wat u told but after some time link2sd is showing failure that "cannot link readonly" can u help me

Your guide works great. Finally I can have all apps I like to have installed at once.

I can tell some experiences with backups.
Before I had blur stock rom with link2sd and changed to deblur central europe rom. After reinstalling link2sd all apps where still gone.
And even after restoring all user apps with titanium backup they were restored to phone memory. I had relink them with link2sd manually and to batch restore with titanium backup twice because it broke down in the middle because phone memory was full.
Unfortunately link2sd is no magically way to have them backed up apps and to be independent from the rom. Titanium backup is still needed but that is fine. Nothing seams broken after restore with TI and relink with link2sd.

lovdanie, it's strange, had no issues with the tested phone yet, I partitioned 500mb and it has already like 200-250MB of apps linked and is working great, no issues.
One thing that could have happened is that you removed the SD card. Are you sure the SD card hasn't been touched or formatted?
bagers, it's not really a magical solution, it's just a way to get more space on a phone that lacks internal memory...

miniProBhashi,
That's why I always use CWM to partition the SD card. As I don't have it on the Bllur, I put the card on another phone I have with CWM and it always works... Maybe if you have a linux PC you could do the same thing...

Hi, I just partitioned my SD card. When I open the Link2SD app, it did prompt me to select the file system of the SD card's second partion, however, after I select FAT32/FAT16, Link2SD could not gain root access, there's no pop-up of indicating me to select "Allow" on the Superuser Request. Now wot do I do. Please help, thank you...

Well, I would start checking the SuperUser app to see if there is some exception in there. If you don't have it, check out if your phone is rooted by installing some other app that requires root access.
If not, check the root method for your phone.
If it's the Motorola Flipout, download version 1.6.1 from this thread, install it and run it:

Hi,
I would try on a Galaxy Ace forum to check for the rooting process and validate if your phone is really rooted. When you are 100% sure you have root you can come back to this post and we can check if there's some other issue...

Hi,
Have seen similar problems when using ext filesystems. Are you 100% sure that the secondary partition on the sd card is fat32? It really should work on the flipout without any issues.
Remember that you need:
* Rooted flipout
* Partitioned sd card (secondary partition must be fat32)
* Link2sd opened and allowed to use root permission
If you are sure you did everything stated above, we can look at it with more detail. What tool did you use to partition the sd card?

root permission
hi,
i have installed Link2SD from Market to my lg optimus p500 os,gingerbird2.3.3,when i stared to move app to sd it asks root permission.
so pls guid me to activate root permission in my device

Hi,
It doesn't make much sense to use Link2SD if you're on Gingerbread as your OS natively can copy apps to the SD card (at least some of them). Just go to "Manage Applications", and select the app you want to copy, there should be an option to "Move to SD"...
If you still have some good reason to use Link2SD, you should first look in a forum for your specific device to find out how to obtain root (I cannot help because it varies for each device)... Once you have root access, I can help you out with this process.

When I partitioned mine I used GParted Live. It's a Linux-based boot disk, but you don't really have to know anything about Linux to use it. Just download the .ISO and burn a CD, pop it in your PC and boot off it. Its free, graphical (not command line) and relatively easy to use. There is also an option there to set it up to boot live off a USB drive, but that's a bit more involved to set up.
gparted . sourceforge . net / livecd.php (sorry, it won't let me directly post links yet)
If you can burn a .ISO to a CD, you can probably figure it out. Just make sure you pay attention to which disk you are partitioning (look at the sizes) so you don't accidentally re-partition the hard drive in your PC.
EDIT: If there is anything you need to back up off the SD card, I would do that in Windows first, and then copy it back using Windows after. You CAN do this with GParted Live but there would be additional steps to mount / unmount the Windows partition on the PC that you want to copy to.

the bootstrapped recovery seems to be having a partitioning tool.
Maybe im wrong, haven't used it though

use External sd card to install apps on it by lin2sd

This is a step by step guide on how you can run Link2SD on your device. This tutorial will work for both stock and cutom ROMs. For ClockWorkMod Recovery users, you can check the other guide below. Follow all the instructions carefully to eliminate possible problems.
First you have to download Mini Tool Partition Wizard Manager. You can download it HERE.
Insert your SD card to a card reader and open it on your computer.
Back up all your files to the computer because partitioning will wipe your data.
Open Mini Tool in your computer. Locate your SD card (be careful in choosing and make sure not to choose the drive of your computer)
Right click and choose Delete.link2sd 3
Right click on it again and choose Create New. Create “FAT32″ partition (This is where all your media files will go. Be sure to make it bigger than the 2nd part)
Select “Create as: PRIMARY” link2sd 4
Next, create an ext2/ext3/ext4 partition (if you’re on stock ROM, choose ext2). This is where your apps will go. I suggest a value of 512Mb or 1Gb would be big enough but if you insist you can go as high as 2Gb.
Select “Create As: PRIMARY” (make sure that it is both set to primary because it will not work if it is not set to primary) link2sd 5
Click the “Apply” button on the top left corner and wait for it to finish the process. Done.
Put back your SD card to your phone and switch it on.
Download and install Link2sd from Google Play Store.
Open Link2sd. You will be prompted to choose between ext2, ext3, ext4 and FAT32. Select ext2. link2sd 6
It will say mount script created. Reboot your phone now.
Open link2sd and if the message doesn’t show up, you succeded.
Go to Link2sd>Settings>check the autolink (to automatically move apps upon installation)
If you already have some apps, select “move to phone” then after moving select “Create Link” (be sure to check the three files: app, dalvic-cache and library files)
link2sd 2link2sd
To check your memory, select “Storage Info”. This will show you the current state of your internal memory, FAT32, and ext2 partition. link2sd 7
Now you’re done and ready to install vast amount of applications as you wish!
FOR CLOCKWORKMOD RECOVERY USERS ONLY( ALTERNATIVE METHOD)

Back up all your files to your computer. Partitioning wipes the files of your SD card.

Choose your SD-ext size (if you’re using a 2Gb SD card, choose 512Mb. If your SD card is 4Gb or greater, you can choose 1024Mb)
Select 0 swap
Wait for the process to finish. Reboot.
Download and install Link2SD from Google Play Store.
Open Link2SD you will be prompted to choose between ext2, ext3, ext4 or FAT32. Choose ext4.
Follow instructions number 14-20. DONE!

There are many things wrong with this guide. Never partition an sd-card with CWM or Minitool partiton wizard. You will probably end up with a damaged sd-card, or most likely with a faulty sd-ext partition. Use Gparted instead.
And why use link2sd when you can install an init d script that works way better?

I appreciate your guide but i have used and still using minitool partition and linktosd .its working perfectly with no lag still after 1 month of use
not all roms support init d script nor 4ext recovry support is avainable for every phone

Thanks. I know 4ext is only available on some phones, that's why I recommend Gparted.
The difference is that Gparted makes a properly linux ext4 partition. I have a friend that used minitool, and he finished off his 16gb class 10 card.

this only for android 4.1.2 or below and not for 4.2, is that right?

Dont know really becoz I used it upto 4.1.2

KK-Boot 0.5.2 have a feature to make the external SD card (/storage/extSdCard) as an internal media (/storage/sdcard0) and allocate all the internal media space for apps. Users still have full access to internal storage because the internal storage (/data/media) then mapped as external SD card. Cleaning /storage/extSdCard will give more spaces for apps
