[HELP]Apps/Data on SD: Switching to new SD card

Is it possible if I installed apps/data on SD card to switch to another card and install apps/data on it? I removed my current card and my phone stopped working. I will take help from anyone who has it.

if you want to, you should be able to copy everything to a backup folder and upload to another sd card. you need to do this in linux cause windows does not natively read ext2 partitions. shut down your phone, remove the micro sd card, put in your computer, copy everything to the backup folder, then re-partition your new (hopefully bigger) micro sd card. put back in the phone and boot it up. i have never tried this, but it should work, just as long as you have the ext2 partition the system can read from. good luck.

I agree fully with corp769. In addition, two important things to remember are:
* ext2 must be the second (primary) partition
* you must preserve UNIX access permissions by copying apps and data directories with cp -rp ! That's the reason apps on SD doesn't work without repartitioning.
* you must use a separate card reader, you cannot do this while the card is plugged into your G1. (Unless you can do some fancy mounting/unmounting stuff on the phone, that is. It's certainly easier and safer to use a card reader).
I too have never tried this, but it should work.

i did this on linux from a 2G card to a new 8G card .. my partitions are named so i utilize naming to distinguish one partition from the other:
make two folders on your linux desktop .. "SDD1" and "SDD2" .. the FAT32(sdd1) can be click-and-drag to the desktop folder .. the EXT2(sdd2) needs to be run inside Terminal to retain the permissions (unless someone know a better way)
ie: sudo cp -a /media/sdd2/* /home/LucidREM/Desktop/SDD2
then switch cards
ie: sudo cp -a /home/LucidREM/Desktop/SDD2/* /media/sdd2
obviously substitute your name for mine unless you call yourself "LucidREM"

In the exact same process when you have an error nfs :
In linux with the card reader
unmount both vfat and ext2 partitions and type :
fsck -p /dev/yourext2partition.
fsck.vfat -p /dev/yourfatpartition
that's how I manage to recover 2 MicroSD card

If you want to go the GUI route - go grab a copy of the GParted Live distribution. Put that on bootable media (whatever your case may be, USB or CD/DVD) then boot into GParted and use the GUI to copy and paste the partitions over. GParted will do a consistency check and fix any errors in both partitions first, then copy over into the new SD card.

Thanks a lot for the help everyone. I will give this a shot when I get home. Appreciate all the quick responses.

no prob man, just let us know if it works for you or not.

If you don't have linux, is there a program for windows or mac I can use to do this? Thanks

Yes download Wubi (which is like Linux in a box, and can be installed in like 10 minutes and ready to use and removed like a normal program) or download Paragon Partition Manager 9 Trial Version, it must be version 9 not 10. I recommend Wubi however, much easier, and who knows, you might fall in love with it like I did.

I tried the LucidREM instructions and it is looping on startup.
Is there a different way to do this?

Simplest Method
Just in case people still want to know how to change SD cards (ext partition and all), which I suspect will happen a lot since the 16GB cards are going to start dropping in price soon, here's the simplest and best way I know how to do it. I have done this a bunch of times without any issues. I've even used this to go from a G1 to a myTouch (with minor compatibility changes, of course). But simply changing/upgrading SD cards is a breeze.
First thing's first. You will need bart.sh which can be found here: http://forum.xda-developers.com/showthread.php?t=562292. If you are using a myTouch or simply don't want to bother typing commands, use Amon_RA's wonderful recovery menus with bart.sh already built in. The Nexus One version can be found here (http://forum.xda-developers.com/showthread.php?t=611829) but there are links to the recovery menus for the G1, myTouch, Hero, etc. on that page.
You will need to be familiar with how bart.sh works and this is way beyond this post. There is a ton of information on the bart.sh thread. So here are the steps that need to be done.
1) Run bart.sh, either in recovery console or via recovery menu, to backup your entire ext2/3/4 partition (as well as nandroid for simplicity).
2) Back up the fat32 portion of your SD card as you normally would by mounting your SD card to your computer. Make sure that this includes the new bart.sh backup which should be located in the bart folder in the root of you SD card.
3) Partition your new SD card using the method of your choice. Amon_RA's recovery menus have an easy and painless method for this but you can use parted or any other method you choose. If you use your device to partition your new SD card do NOT boot your phone after you partition the card. You will want to finish Step 4 first. Amon_RA's recovery allows you to mount your SD card from recovery to help you complete Step 4 if you do not have a SD card reader.
4) Using Amon_RA's recovery menu or an SD card reader copy the fat32 partition, which includes your bart.sh backup, from your PC to the fat32 partition of your newly partitioned SD card. From the recovery menu, restore your bart.sh backup.
5) Voila. You now have all of your partitions moved to a new SD card.
This process can be simplified into one sentence. Do a bart.sh backup and restore it to the new SD making sure the SD card has the proper partitions and that you don't forget about the fat32 partition. The above is just a list showing the proper order so that you don't lose any data during the process.

after rooting, microsd won't resize

So I went through the process of rooting the nook color tonight, and got everything working great.
However...now my 16gb microsd is a 40mb microsd. I'm sure I'm an idiot, and I'm missing something...but how the heck do I talk this thing into being a 16gb card again?
(it's the card I made into the bootable nooter image, in case this isn't coming through clearly)

Here is how I did it.
1.type 'diskpart' in the run prompt
this will bring you to a DOS prompt​2.type 'list disk'
this will list all the volume available​3.type 'select disk #'
in the #, use the number from your SD Card​4.type 'list partition'
it'll probably be partition 1, be just to be sure​5.type 'select partition #'
select the bootable SD Card partition​6.type 'delete partition'
now the 40mb partition is deleted and you can reformat under Disk Management​

that didn't work for me, but it jogged my memory enough to find disk management in windows 7, and delete the partition. Thank you!

I just put my SD card back in the nook. Once there I unmounted it and formated it. got my 4 Gb back. Nice and easy.

I did the same thing.

I tried that, but didn't have success, hence the question and workaround.

If you're using a windows machine try download the official SD Formatter from:
http://www.sdcard.org/consumers/formatter/
It will wipe out all your partitions and formats the card using 32kb allocation units vs the standard windows 4096 which gives better read/write performance.

this worked for me thanks

Burned wrong image - Full SDCard Access

so i either don't fully understand how images work in the SDCard itself (not on the nook), or i did something wrong and don't know how to fix the card, but at any rate, i managed to burn a 128meg image onto my 8gig sd card, didn't like the image, and now can't figure out how to get the card back to a regular 8gig card!
would love some direction. tried to search but must not be using right keywords.
didn't see any kind of format or clear option in the winimg program we're using.
thanks!

On your Nook I believe you can go to Settings, Device Info, Mount the SD card if it's not mounted and then format it. It'll erase it and you'll have a blank SD card. If you're going to put a different image on the card I don't know if you even need to bother formatting, but I' not sure about that stuff.

does the nook format work differently than a computer format? because i burned a 128meg image onto an 8gig card and now even a computer format won't get the whole 8gigs back... just the 128 megs. it's like it's got invisible partitions on it or something.

Partition
Try EASEUS Partition Manager to change the partition size/format card.

byproxy... here is the easy way...
1) Go and download "EASEUS Partition Master 7.0.1 Home Edition" --- just google it (the home edition is free and downloadable)
2) Put your microSD card into a card reader and plug into your computer
3) install EASEUS onto your computer and run the app
4) Once app is started, located your microSD card amongst the list of drives listed
5) select each one of the partitions on the SD card, and delete them individually
6) Once all partitions are deleted, make sure that you are still selecting the microSD card, and select the option to create partition (it may just say create)
7) Make sure you select FAT 32
8) Then select FORMAT
9) Lastly, click on APPLY and it will do all the things above. So in short you select all the actions that you want... and only in step 9 will it execute all those actions.
Please make sure that any changes you make are to the SD card and not any of your other drives. Last thing I would want is for you to accidentally format your Computer, NAS, or your non-SD card. =)
Enjoy...

sweet. exactly what i was looking for. thanks gents!!!

OK, but isn't it easier just to do it in the Nook or am I missing something here?

...worst case there's a low level SD card formatter from Panasonic (IIRC might be Toshiba) that will do a complete low level format and has recovered uSDs for people using them with Nintendo DS dev carts...
A Google search should turn it up, or a thread on a DS site which might have a link to it. It'll be a little windows program...
(I believe that windows and most devices just do sort of a quick format of the uSD, and so can't recover from some problems like re-partitioning of the card... so monkeying around with a partition editor and assigning the card to be one big partition then re-fromatting under windows or some other device MIGHT work as well...)
[EDIT]
oops, I see post #5 has the re-partitioning solution as well... another way to do it would be to backup an image of the card BEFORE burning something like autonooter on it then restore that original image to card once finished with whatever you were trying out... it's what I did when I tried autonooter w/my old 128MB card, in linux in my case a
dd if=/path/to/sd/card of=./somefilename
dd if=./autonooter.img of=/path/to/sd/card
then later
dd if=./somefilename of=/path/to/sd/card
sd card path under linux is likely to be /dev/memc<device ref characters?>
You should also be able to do this under windows with the utility recommended for windows users to use with the autonooter image, as I'm guessing that it's just a GUI wrapper and a windows compiled version of the dd utility...
[/EDIT]

Some believe that there are issues with formatting on Nook... depending which ROM you are running. The surefire and safe way, is to do it from a PC.
Nook should format, but may not partition correctly.

No, the Nook will format the *device* and not a partition, so it always works. But you don't want to do it if you've installed NC or HC to eMMC.
If you're using Stock rooted, just boot without the card in the device, put it in, format. Done.
Or if you're on a real os just format the device... mkfs.vfat /dev/sdX

working with SD cards

A couple of questions:
- I've read that the SD based images of Froyo and HC actually put 4 partitions on the SD card. It was suggested that, since the 4 partitions likely won't use all the available space on the SD card, it's possible to expand the last partition to use the rest of the card. I downloaded EASUS partition manager and tried to do that but it appears that it's only seeing the first small partition. This is on Win7 64 bit. Is EASUS the right tool for this and, if so, how do I get it working.
- So far I've used win32diskimager for writing the images to SD and it's worked well. Since I've only got a couple of SD cards I wanted to make a backup of the contents of one so I could try a different build on it. When I read the card I only got a 100+k image instead of the 2G image I expected. I suspect that's the same first partition that EASUS seems to show. How do I create an image of a card?

hmm....that is kinda weird. I use EASUS myself and have Win 7 64 bit also. that said I just did the process to expand my bootbale HC sdcard to get all the sdcard storage space back after burning the bootable image to the sdcard. One thing I did notice tho is that if you have EASUS open prior to plugging the sdcard into the comp it doens't read correctly. So I reboot my comp leaving the sdcard plugged in. Once the comp came up I went into my comp to see what the size showed. The card was labeled a "boot" and the size was only about 120Mb. I then closed the window and fired up EASUS and it showed as Disk 2. Under that I have the small boot partition, along with an ext2 & ext3 partition each about 675Mb in size. Last partition was the sdcard and under that showed "unallocated space" of about 13Gb. I clicked ( ie highlighted ) sdcard and then was able to click the Resize button on the tool bat in the progrm. From there I grabbed the slider and slide it all the way to the right and it set the sdcard partition to just under 14Gb. Click okay and then last but not least just click the Apply button on the tool bar and it resized it.
As for your other question I can't comment at this time as I don't have my Nook or my sdcards with me to take a look at what they show up as for size when read. I'll try to take a look when I get home and report back on what I'm seeing.

Have you tried using the Win32diskImager read function?
I'm not near my computer, but I am pretty sure there was a read function in there..
Sent from my LogicPD Zoom2 using XDA App

Yes I did use the read function but the image file created was only 100-some k, way smaller than the original Froyo image that I wrote to the card.
I wonder if the SD slot on my laptop and/or the SD adapter that came with the card is funky, preventing a proper read of the card. I'll have to try the other adapters or an external card reader I have to see if I have better luck.

If I'm not mistaken the 100-some k partition is normal as it is only reading the boot partition IMG. My 8Gb bootable sdcard comes up showing as 119Mb when you look at it in My computer and check the properties. Reason being is Windows is not reading/seeing the other partitions. However in EASUS all the partitions ( 4 of them boot,ext2,ext3, and sdcard )should show up and that should allow you to resize the sdcard as that is the only thing you want to mess with anyways.
As I said earlier I will check this out tonight when I get home as I have at least 3 different bootable sdcards, and also a 16Gb sdcard that has HC flashed to it so I can run the OS off of it and still leave my CM7 setup on eMMC. One one darn day I don't bring it with me to work......lol, typical I tell ya.

I had tried to extend mine using windows DISKPART at first, and all of the partitions were listed, but they were all marked partition 0. EASUS did the job for me when I couldn't select the proper partition in diskpart (all of them being partition 0 confused it). Windows Disk Manager also saw all 4 partitions, but couldn't do anything with the last partition. Verify you've got 4 partitions using either diskpart or disk manager - if you don't see all 4 partitions in those programs, something went wrong with your image burn.

Unlikely that anything's wrong with the burn since Froyo boots and runs fine off the card.
I tried the card in the other adapter I have in the laptop slot and EASEUS still doesn't see the other partitions. Then I tired a cheap USB reader I have. EASEUS saw the partitions and allowed me to resize the fourth partition. Another hurdle cleared. Note to self use card reader from now on

nook dual usd card files tranfer from comuputer

Hi
Please respond to the following. I tried a lot to look the answer to my problem in the forums, but could not find it (or did not get the right forum)
I dual booted my NC with CM7.1.0. It was working fine without any problem, but suddenly stopped entering into the main screen. Whenever i on the nook the Cyanogen loading ... screen comes and then screen flashes and turns lit black.. the NC is not off but it does not reach to the main system. I tried to use update the CM by copying a new file to usd, but it did not let me do so.. computer hanged. I do not want to format it as it has some .xls files in documents folder in the 4th partition of usd. Can someone please tell me how to extract those files using computer's sd car slot ( I can not use nook usb option as it is not booting CM) and how to recover the older working condition.

I assume you have stock working on emmc. I have a flash file that you can temporarily flash to stock to make it read the fourth partition of the SD as 'sdcard'. Go to my tips thread linked in my signature and item B3 in the second post (last paragraph). It tells you how to modify stock to read that partition. If your stock is rooted, you can just edit the file yourself. If not rooted, you need to flash one of the files attached to the post. Instructions are there. After retrieving your files you can revert stock back to normal by re-editing the file or by flashing a second zip, or just keep it that way and use partition four for both systems. Then you can start over with your verygreen SD and reinstall CM7.

could not get it

Thanks for being so patient. I dont think it is rooted and the stock nook is touched as i follow a link provided in this forum to boot usd and dual boot nook without losing warranty to install cm7 on a usd.
When i use boot the nc, i see following responses
1. boot without usd: boots to original nc, all files and applications are there and work perfectly fine.
2. boot with usd without going to boot menu: cyanogen loading banner shows up and then screen flashes. .then a lit black screen .. nothing happens after that
3. boot with usd and selecting emmc in boot menu: boots to original nc but hangs at home screen
4. boot with usd and selecting sd (external storage) in boot menu: cyanogen loading banner shows up and then screen flashes. .then a lit black screen .. nothing happens after that

Your SD is definitely messed up. You will need to reinstall after we get your file saved that you want.
You will need a spare SD card that you can put my bootable CWM recovery on.
Go to my tips thread linked in my signature and download to your PC three files attached there. The one that starts CWM... and the two that start update-stock...
Extract the CWM zip. It will have a 200Mb .img file in it. Burn that to the spare SD just like you did when you made the verygreen SD. Once that is burned and you can see it on your PC, copy the two update-stock... zips to it.
Remove that SD from the PC and put in the nook. Boot. The CWM menu will come up. Select 'install zip from sdcard '. Then select 'choose zip from sdcard'. Scroll through the list and pick 'update-stockemmc-vold-fstab-modified-for-partition4.zip'. Then confirm the selection. It will flash the zip. Remove the CWM card and reboot to stock.
Insert the verygreen SD and you should be able to connect your USB and see partition 4 on the PC as 'sdcard'.
To return your stock to original after retrieving your file, just go through the process of flashing the other update file with CWM. But most people like leaving it modified so that they can always use just one SD for both systems.

I did exactly same, but could not see partition 4 on the pc as 'sdcard'. I see two drives 1. mynookcolor ( i can access all files in it), and 2. a removable disk drive I:/ ( that i can not access). I do not see my files (see pic below) those are on the 4th partition of sd card.

You need to mount the card in settings. Go to settings, device info, SD card. And choose 'mount SD card'.

If it says unavailable and the first two are greyed out, that means it is not mounted. Pull it out and put it back in... wait you had the cable unplugged when you checked that didn't you? You should have.

What I am asking is with the USB cable removed, what does the settings show? If you remove and replace the SD with the settings window open, is there any difference? You say it detects it, how do you know that?
Edit: I have been searching for a solution for you. There are two ways to see those files with your PC. To view it in Windows, you must make several complicated changes to your drivers. I'm sure you do not want to do that. The other way is to use Linux. It has the ability to see and mount multiple partitions on an SD. You can either find someone who has a Linux system to do it for you or you can make yourself a Ubuntu Live CD that you can boot with your PC. None of these options are easy, which is why I was trying to do it the other way on your nook.
I don't know why your system is not mounting that SD properly. Even if those changes I had you make were not there, it should at least mount partition one on the nook.

without usb cable,
1. sd card removed
sd card memory (not available)
Unmount SD card (unmount the sd card for safe removal)
Format sd card (format (erase) the sd card
All are grey/inactive
2. sd card inserted
sd card memory (not available)
Unmount SD card (unmount the sd card for safe removal)
Format sd card (format (erase) the sd card
Now top 2 are inactive, but the third one (format) is active
whenever i insert a card it shows small box flash that shows sd with tick mark, and when i remove it again shows the sd flash box with cross mark.

The card is not written correctly... if you format it in the nook... you will see it on your computer... then you can remove it... and try writing the uSDcard image again with win32diskimager

Dizz, he was trying to figure out how to get his data off of partition 4 before he reformats and starts again. I was hoping he could do it with the nook, but it is not reading it. I had him modify emmc so it can see partition 4, but no luck here. Do you have any ideas?

I just had another thought. Put the card in the PC and open with your partition software. Delete partition one, two and three. Then maybe windows can see partition 4, since it is now partition one. You may have to move it to the beginning of the SD, but I don't think you have to.
Edit: I was able to test this on my spare SD card with the EaseUS partition program and it works. Be sure to give it a drive letter.

No, your installed apps are stored on partition 3. But if you bought them, google lets you redownload and install to as many devices as you want, as long as you are logged in to your Google Play account. What you will get back is things you had stored on 'sdcard' (pictures, books, music and other files like your xls files you wanted, what you saw in that screenshot you posted.)

I had thought of this before I commented about the SD being not formatted correctly... should only have to delete partition 1 ("boot") since windows should use the first fat partition....
However...
Since the nook doesn't show "unmount" or ""sd card memory" active... it is certainly not reading partition 1 correctly.
He can flash my B&N 1.4.1 with SASD vold.fstab edits to see partition 4 (if it can read it) and transfer everything from that partition.
