[TUT]How to partition your SD card

Since I've read much about this in different threads (people who couldn't find out how to do it), I thought I could share some light on it in a separate thread...
For starters: DO NOT PARTITION YOUR SD CARD WITH ROM MANAGER!!! This will partition your internal memory, and will brick your phone... To get back to stock please follow this thread.
Okay... First off to the linux users out there. There already exists a very nice tutorial on how to partition a SD card in ubuntu(the steps will be very similar in other distros too). For the ones that want to use gParted, theres an live cd here.
For myself, and all the other windows users, read on
1. Get yourself a copy of "Paragon Hard Disk Manager".
2. Install it through it's instructions.
3. Mount your SD card to your computer, and make sure it's recognized.
4a. Probably the fastest way: Go to "my computer", right click on your SD card, click format, choose FAT32 and format your card.
4b. Launch PHDM, and select "format partition", choose your SD card (next), choose FAT32 (next), "Yes, apply" (next) and your card is beeing formated to FAT 32.
Now your going to make the ext2/3/4 partition.
5. Go back to the main menu of PHDM again.
6. Click "create partition", choose your SD card (next), make the new partition size (I picked 1GB for my ext) and pick ext2/3/4 (next), "Yes, apply..."(next) and your card is partitioned and formated to ext2/3/4.
Good luck

Or if you're like me and have a previous phone with Amon_Ra's recovery. Put the SD card that you're using in the Vibrant into the G1 and load into the Recovery and "partition sd card" and all you'll have to do is set up the size of the partitions. It'll take less than a minute to do this. Far more easier and im sure a lot of people from the Vibrant community were upgraders from the G1.

And partitioning your SD card does what exactly?

Allows you to use the data/cache to SD mod to speed up some stuff on the phone. For most of us, it has nearly eliminated the lag.

i tried this and its not as easy as you state. The instructions aren't clear either. I have blank CDs, added the file but it also says download something else which wasn't there. Whe you try to open the app from the cd, it doesn't know which program to choose to open it.

Ubuntu comes with a disk utility that is really easy to use.

You do know you have to burn it as a CD IMAGE not as a file, right? If you're on Windows, Infrarecord is free and works well. Linux and OSX come with software that can do it. Then you boot from the CD, there isn't a need to open an app, it should launch itself once booted. Then select the SD card and partition. It even formats the partitions for you.
It's not as easy as some, but it's a whole lot easier than fdisk. Free software is generally not going to be as "pretty" as paid stuff. If you want the pretty, pay for Partition Magic, Paragon, whatever, there's a few options out there.

+1 for gparted boot cd
It has saved me several times when I've screwed up my hackintosh installs.

Paragon is saying it cant format my sdcard....

Do you have the paid version or the demo? To format you'll have to have the paid one...
/edit
Updated first post with link to gParted live cd...

Paid version (Thx Utorrent), but so just to clarify, so do I go straight from Fat32--> to Ext4 option? Or do I have to choose ext2, then create another partition (ext3), then ext4?

You have to boot this cd once you burn it. Be careful not to partition your PC's hard drive

You can go straight from having the whole SD in FAT32 to partition your card to ext4

i spent the better of the night trying to format my card. sandisk 16gb class 2.
i fire up PHDM after formatting the card through my computer. i keep getting an error message when i go through the create partition wizard saying that my external sd card has four different partitions including an extended one, which doesnt make sense because i just formatted it. ill attach a picture when i wake up.
i then tried to use paragon partition manager. my sd card shows up. yay. i proceed to create two primary partitions: 13.6gb fat32 and 1.5gb ext3. everything goes good. now, when i unmount my sd card, the phone then says that the external sd card is corrupted and that i need to reformat. reformatting takes me back to square one. 14.8gb fat32. i tried letting the phone format the memory card and then use ppm to do just a 1.5gb ext3 and success. it worked. i installed deodexed rom and saw that my boot time was 2-3 min as compared to the general 10-12 min i was reading about. downloaded quadrant and registered a beautiful 897. i also went to go put back all my files onto my memory card and it asks me to reformat the card. square one again.
last resort i used gparted. tried using 13.6gb fat32 and 1.5gb ext3 and gparted gives me an error saying it cannot complete it. i dont remember exactly the error because im not too familiar with linux.
if anyone has any ideas or alternatives that ive missed, please chime in.
EDIT: i tried using two different memory cards and they didnt work as well. there has to be something im either missing or doing wrong. =(

Can't believe none of you guys have a previous Android phone with Amon_Ra installed. It practically makes partitoning a SD card a joke.

Fellow rookie to rookie step by step guide
This is my first Android phone and really my first experience with “programming.” I am using a Windows 7 PC, a rooted phone and a 16GB class 2 external SD card. Here is my step by step guide to partition your external SD card (That is the one that has/had Avatar on it) using free software:
1. Download and install the ISO recorder from alex fineman. Just Google “alex fineman iso recorder.” If you don’t have his program you will not be able to burn ”gparted live” as an image to a CD which is the next step
2. Google “gparted live” and select the sourceforge site. Next select “To install GParted Live on CD, download the .iso file and burn it as an image to a CD.”
3. I tried the most recent stable version but it would not load so I ended up using the most recent “Testing release” which worked on my Windows 7 PC
4. Download the gparted-live-0.6.2-2.zip which will now have an ISO extension since you downloaded and installed the ISO recorder in step 1
5. Open the gparted-live and follow instructions to burn a disc image
6. Connect you phone and enable USB mass storage (I used my work BB rather than the Vibrant in case I messed things up. Others have recommended an old phone)
7. Start your PC with the gparted-live disc in and get ready to hit the “esc” key to get into boot up. Select “boot from cd”, “gparted live default setting”, “don’t touch keymap”, 33 (for English), and “0”. You should now get the gparted-live interface and there should be two devices connected. Your PC and the phone with its external SD card
8. Delete the existing SD card partitions but make double sure you are on the phone and not your PC before you do this. Next, create the primary, fat 32 partition and leave no more than 2 GB of space for the next partition. Create a primary, ext3 partition and select accept to create the new partitions. That is it. Exit gparted and reboot your computer without the disc
I did the repartitioning so I could apply the custom ROM from anomalous3 over in the development section. I would highly recommend his ROM as a next step in your development as the phone is incredibly fast after installing it. As I said, I am a 100% rookie but the phone is now blazing fast (over 1,400 from low 800 on Quadrant. I really have no idea what it means but the difference is fantastic). Best of luck to my fellow rookies/noobs/nbs/newbies

[Q] Problems with SD cards / running Honeycomb

Hey guys, I think this should be a pretty simple question to answer but I can't find anything specific when I search google. I've been having trouble running different builds of Honeycomb on my nookColor: v2, 2a, and honeybunches all would not let me connect to wifi. Everytime it would go to connect, the signal would drop to zero and nothing would happen. Any thoughts on this?
Also, since I only have 2 microSD cards I would use Easeus to delete the partitions on the disks and then use SD formatter to reformat the cards so I could install a new build of Honeycomb to check the wireless. However, the capacity of my 8GB card has gone from ~7.6-7.8GB to 7.46GB when i am trying to format it for the next time. Easeus shows a 7.647GB unallocated partition, but the formatter wants to format it to 7.46GB. I don't understand why it has gone down, and it makes me worry that I unwittingly lost space on my SD card. Have I screwed up my cards, or can I get this mystery space back? Please help!

Remove SD card from Nook and boot into stock. Insert SD card, go to settings, Device Info, SD card, unmount sd card, then format sd card. This will/should delete all partitions, format and restore all usable space on the sd card. From here, download and burn the honeycomb image to your sd card. (I recommend ubuntu, dd command. Open terminal, navigate to the directory that contains your nookhoney image. Once there type; "sudo dd if=nookhoney02.img of=/dev/mmcblk0 bs=1M" without the quotes. Note that nookhoney02.img could be nookhoney02a.img or the honeybunches image depending on which you are using and mmcblk0 could be mmcblk1 etc. depending on what the name of your sdcard drive is.) After the image is done writing, power Nook down, insert sd card and boot Nook. Also, the burning process can be done from windows using winimage and what not, the whole ubuntu thing was just my recommendation. Hope this works for you, any more questions, just feel free to ask. Also, I apologize if this is repeat information, just giving the full experience.

just use dd command in linux or osx will erase all the partition, don't need format or erase the card first.if you do so the sd size will not decrease.

Have you tried turning WiFi off and then on again? This seems to work for me when wifi is acting weird.

by turn off, do you just mean press the wifi button in "Wireless & Networks" or the enable disable buttons in the dev tools? i've tried the first solution to no avail. I guess I could try messing around with the dev tools.
The nook doesnt have to be rooted for me to run this off my SD card right?
EDIT: I just went over to B&N to check if their wifi works. It does, so i don't know what the issue is. Possibly because my university uses 802.1x EAP for their network? The only thing that is fishy is that my nook at stock would connect fine.

Answer to your first question yes turning off and back on in Settings>Wireless.
I know I had mine working on my uni's network which has 802.1x but can't remember if it was stock, Froyo, or HC. Not currently on campus so I can't try it for you.

Google "SD formatter" and download the application. It's free and very easy to use and will format your SD cards.

That's what I was using, but the size seems to keep getting smaller and smaller. I'm losing about .01GB per format.
EDIT: Okay now the wifi is working in the dorms, and i hate to say this, because it's so humiliating, but I think i was using the wrong password to log into my wireless network. Which is probably why it hung on connecting. Which makes me feel dumb.

[Q] I have Rooted the Nook (SDCARD) but I cant get Clockworkmod to work

So I have installed the Rom on the SDCard and I can see the Rom Manager but I took the SD Card out and put the Google App zip from here http://wiki.cyanogenmod.com/index.php?title=Latest_Version on the SD Card booted the nook back and then went into Rom Manager to "Boot Into Recovery" but nothing happens the system just reboots and I don't get that screen with the orange text to let me install the apps from the SD card.
Keep in mind that I rooted the nook the soft way buy making a bootable SD card.

It doesn't sound like you've actually rooted the nook - you've just booted into an alternate ROM on the SD card. If you want to get into CWM, you can either create an SD card which has CWM and will launch it when you boot with the SD card in, or you can install it to internal memory so the SD card isn't necessary.

Thanks for the notes. I basically figured out I didn't really need it if I used the trick of turning the unit on while holding the N button. As a follow up question. Now that I have everything setup can I make an image of this SD Card and put that image on a bigger faster card? Or will I need to start over?

If you use dd just to copy the raw data on the SD card, you'll get the advantages of faster speed, but the partition will be the exact same size. If you want to take advantage of the bigger space, you'll need to partition the SD card and copy the files manually.

So I don't know much about dd although I have seen it on the site before so I can look that up. As for the partitioning tool I know the first partition has to be 'boot' not sure on what size it has to be or any other specifics do you know any of that data? Also thanks for taking the time to answer all of this. I am hoping that this will stop some of the Force Close issues I am seeing.

The easiest way is to use http://forum.xda-developers.com/showthread.php?t=1000957 to install CM7 to your SD card. The image takes care of creating the partitions of the appropriate size. As for writing the image itself, you can follow any guide for dd, or use WinImage on Windows which is probably a bit easier to follow.

Yeah but I wanted to know if I could copy all my date over. Just by like copy and paste sort of thing. In other words I dont want to get to carried away on installing all this stuff then have to redo everything once I get a better card.

[Q] Can I clone my CM7 SD card?

My girlfriend loves my Nook Color, and wants one too -- exactly the same as mine.
I am running CM7 off of my SD card. It took me awhile to customize my NC to get it just the way I like it.
Rather than go through the whole procedure on her Nook, can I just install CM7 and gapps, and then reboot with a copy of the contents of SD card?
In other words, I don't want to have to download all those gapps again, set up her home screen, etc.
Thanks!

You can do it that way by backing up all your apps to your SD card, copying to your computer, than transferring to the new card and reinstall. Use Titanium Backup or App Monster for the backups.
Or, you can make a clone image of your SD card on your computer and write the image to the new card. Your 2nd SD card will then be an exact duplicate. Log in with a new gmail account to separate them.

Wow, that is complicated. I just copied all the files from my 8gb card to my 16gb card on my computer and everything worked fine when I put the larger card in the Nook.
However, if you want to do all this clone and backup stuff, I guess that's another route.

OK, fine. But you put the new card into the same Nook. What would've happened if you were to put the copied card into another, completely stock Nook? Would it still work?

Unless I missed some config in the image software, it only copies the first partition. My 16GB SD card only got a 4GB image file and none of the other partition were there.
Did I miss something?

You haven't missed anything; the software is broken. The current version has bugs that cause wrap-around every 4GB (i.e., 32-bit integer overflow). Until the bugs get fixed, you should not use Win32 Disk Imager to read or write image files larger than 4GB.

And they all called me crazy down at the VFW!

Hey everyone, I am a long time lurker who has appreciated everything that is going on here but I have an issue. I want to clone my CM7 image to a newer sandisk 8gb class 4 card. I have the older version (0.1) of win32 disk imager but I am not sure how to write that image off of the card onto my computer to then write back. If anyone can lead me to these instructions, I would be MUCH appreciated. I cannot seem to find the exact steps and I do not want to mess anything up. You all rock, thanks for your help if you can reply.

I thought I would post my findings here for the OP and whoever else may need it. I found a way to backup the SD card image and it should be rewriteable back to a new SD card from what I have read. I used WinImage and under the DISK option, I chose "Creating Virtual Hard Disk Image from physical drive" Then chose the SD card and it will then ask you to choose where you want to save it. It seemed to work for me so I am hoping the burn back to my new SD card works as well. Hope this helps.

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

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.

We'll take this one step at a time. Do you have stock nook still on your internal memory? And if you do, is it rooted or just virgin stock?

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'.

It is already mounted. It shows sd card memory (not available), unmount SD card (\unmount the sd card for safe removal), and format sd card (format (erase) the sd card). However, only third option is active others are grey/inactive.

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.

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.
