[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.

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

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

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

Help.

How do you remove the burned custom ROM image off the sd card? I tried formatting the sd card but its still there. I have a 4gb card and its using up the whole space.

where did you try to format it?
If you're using windows, you can just right click the drive in My Computer and click Format. Do a full format, it should take 5-10 minutes. I've had to do this 2 or 3 times since I got my nook and worked perfectly. Alternately, if you're running stock ROM on your nook, put it in (after it's booted up) and go into the settings and Format that way.

You should also be able to format the mSD card directly on the NOOKcolor. Is your NC running a custom ROM or stock?

I use a program called minitool partition manger for windows, you can delete all the partitions and then stick the sdcard into your nook and have it format it...

first time I did the method through windows, it did not work. The third time around allowed me to reformat everything. Thanks for all the suggestions.

[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.

How do I put files onto my sd card that has been made bootable?

I have installed bootable cm7 on my 8gb sd card. It only shows the first partition when I connect it to my computer. I tried connecting my nook color to my computer in both cm7 and stock firmware, but the card isn't readable in either case. In fact when I connected using cm7 it didn't connect at all.
I am trying to put some pictures onto the sd card, but can only get them on the first partition, is there a way to get them on the larger partition?

Enable USB mass storage for the use since it's the only way.
Boot CM7 up, connect NC to PC, look at the NC's notification area, usb icon should be displayed, tap to open then enable USB mass storage.

There is a program developed here on XDA that can mount your micro SD installed CM7 media data partition that you see on your NC but normally can't see when connected to your PC. Normally the pc sees the first partition only (boot). This program will let you also mount your 4th partition on the sd card so that you can add your media files there. Install the program, tell it to mount your 4th partition, and connect your usb cable to the pc. It will show up as a drive letter. You can download the program here:
http://forum.xda-developers.com/showthread.php?p=11322639
This is also very useful for those users with ics preview on their micro SD card.

The app had been integrated into CM7 builds so long time ago, no need to install it separately.

Go to Settings-Storage select 3 dot menu in upper right corner and select Mass Storage. You will then be able to see the nook USB notification.
The nook will show up as a drive on your computer. Use Clockwork Mod Recovery to partition SD card to reclaim space, but with 2gb not much remains for user media (cm10~700mb, ram~512mb, etc).

Tried that. Now when I connect to my PC, I see only one FAT32 partition(boot) and it shows only 180MB size. I do not see any other partition. Do I need to use a larger size card (>2GB) to see the additional partitions.

See my post above with the link. In cm7 there is a setting to use emmc as sd.

For easy access use a wifi connecting app like WiFi File Explorer Pro; see whole card, quick UL & DL of files.

You can also use debugging over network settings in the ROM and use adb...
The first time you do it do this in a command or terminal window:
adb shell busybox mkdir /sdcard/boot
Then every time you use it to transfer files to the boot partition for flashing:
adb shell busybox mount /dev/block/mmcblk1p1 /sdcard/boot
adb push ROMFILENAME /sdcard/boot/DESIREDROMFILENAMEONDEVICE
If you are wanting to transfer files to the "sdcard" partition of the card:
adb push FILE(s) /sdcard/DESTINATIONFOLDER/

Followed those instructions. Still I see only the main partition in windows explorer. Under disk management I see 4 partitions. In my tablet, I see the 180MB partition. Also I see another with .93GB showing up as internal storage. The emmc shows up as another internal storage. Not sure how to get files into it. I am attaching screen shots.

You are only going to see "Windows"file systems (partitions) in Explorer (FAT, NTFS, etc). The other partitions are Linux type partitions (ext, etc...).. Explorer won't see them. Thus the need for ADB.
Personally I sometimes find it easier to place files in Dropbox and then just deal with them on the device rather than through the cable. You will need the Dropbox app on your NC.. available in Play store.

Since CM ROMs have debugging over network support... there's no need for the cable when adb'ing into the device.
