How can I delete my ext3 partition?

I'm going to be getting a new memory card soon, but I want to use my old one in my camera with an adapter. Is there any way to delete the ext3 partition on my current card?
And before anyone says Paragon, I don't really want to pay any money.

google busybox commands and you will know how to

use gparted, and burn it to a cd, your not using warez, and its free

[Q] Newbie CM7 n87 SD backup question

Hello,
As the title says, I'm a new CM7 user (running verygreen's SDcard installer, using the 1.3 generic image, with nightly 87, no OC). This is running beautifully, except for one thing... I didn't use a big enough SDcard to start with and now I'm faced with looking for the right way to migrate to a larger card (or alternatively to make use of the NC's built-in eMMC in some fashion to augment the current SDcard).
Can someone tell me if the following approach will work? And is it the right/best way?
1. Use Win32Imager to make a full disk image of the current card (4GB).
2. Write the image to a new 8GB or 16GB card. At this point I should have a perfect copy except that there'll be wasted space on the card past the final partition.
3. Boot into a Linux recovery type LiveCD and use gparted to expand the final partition to use up the rest of the space.
4. Am I done? (crosses fingers?)
The goal of this move is to give myself some room to drop movies, music, etc. onto the /mnt/sdcard partition (which I believe is called /media by NC Stock 1.2?) Will what I described work?
Thanks in advance,
fuul4nook
P.S. One extra question, will the fact that my NC is a blue dot cause any problems with the idea? And if not, is there any way I can use the eMMC partitions while running CM7 from SDcard?

You should be able to do what you want but use Easeus Partition Manager to extend the 4th partition on the SD to get full use of the card. I don't know what you mean by "blue dot", but you can access 5 gb on the emmc directly through apps if it's music or video. You can also use File Expert or Root Explorer to store what you want on the emmc partition, which will then also be available when you boot into the stock NC rom.

Partition SDcard?

I have a 8GB card. I want to make him partitions. Cate advised me to make them and how to be partition?
I enter the recovery menu and I there partition sdcard

You can follow that, or, another easy way is to install ROM Manager App, and select Partition SD Card from within that app. Then simply select size of EXT and Swap partition and it will partition your card.
Make sure your SD Card is backed up before partitioning, because it will format your card.

3xeno Well I do not know that. how to make swap partition and how that?
I am so: 128mb,256mb.512,mb,1024mb,2048mb and 4096.
If you choose to 2048MB how should I put swap? I write as swap 0M, 32M, 64M, 128M and 256M?

It depends on whether you want to use swap or not. I don't use a swap partition, so I kept it at 0.

thanx you very much friends for infformation

So, the Partition Size of the Ext2... for a 4GB card, 1GB is legit?
I know.... depends on the apps, but let´s say. if I have an onboard Navigation soft, will the maps use the fat or the ext-Partition for their data?
And also Music... like flac, it´ll probably go standard on the fat partition, right?

If you use the app's inbuilt ability to move to the SD, it will be moved to the standard FAT32 partition. Only if you enable additional scripts like DTApps2SD, will you be able to move apps to the EXT partition.
Other stuffs like music and all will continue to use the FAT32 partition. On a stock ROM, without an Apps2SD script, the EXT partition will remain unused.

Thnx for your answer!
I read through the buzz nightly thread and s.o. voted for Link2SD from the market and that sounds to me like the best way to go for sd, since I too believe not everything (especially the cache) should be moved to sd to keep up stability.
For me coming from linux, it's hard to understand why android uses fat at all for data.

External card as ext2?

Can I have external card mounted as ext2? I have files names not supported by fat and sync'ed with dropbox

Yes, you can but afaik there is no easy way to do this.
I formatted my sdcard to ext2 (because I wanted to put large file (image for wikipedia offline) on my sdcard).
I formatted the beginning (~30MB) of my sdcard to fat32 so that the Nook detect the sdcard and does not trigger an error and the remaining part to ext2.
Then I used a script that mount manually the ext2 partition to /sdcard on boot.
This generally works but I have sometimes a few bug in some applications, especially when I connect and disconnect my Nook to my computer...
The best solution would be to find a way so that Android can automount a ext2 partition by itself but I don't know how to do it.

Instead of using the whole card I partitioned the first 4gb as fat16 (msdos) and then set the rest to ext3. When the fat16 space runs out I'll look into making some sort of script to try to mount the second partition. At the moment with the card acts like a normal 4gb card.

is it possible to repartition the nook to be able to use the space that b&n reserves for its contents? I heard that the space for our files is just 250 mb.

yes of course. If you're used to linux repartitioning and the dd command then it's a breeze. If you're a Windows user who've never done partitioning or disk imaging then you can easily mess up.
I'll assume the former.
It's just a case of:
boot with a noogie.img that you've written to a sdcard (root of card, not partition 1)
then plug it in
now you can see all the nook partitions like it's an external USB drive and fdisk, cfdisk, partitionmagic or whatever you want
Obviously you're gonna want to backup first because if you mess up the only way to restore would be asking one of us off this forum to break the distribution laws and send you a 2gb (or whatever it is) image.

Has someone tried editing /system/etc/vold.conf to get a ext-formated SD-Card mounted?

I checked, I had modified it adding a line "partition 2" in the section "volume_sdcard2" so that Android does not show the message "SD card blank or has unsupported filesystem".
But I couldn't make it mount a ext2 sdcard itself. (if you know how to do it without using another script, I'm interested)

Time to resurrect this thread.
FAT is ugly. File timestamps are in local time (whatever that means, summer? winter?).
The Nook vfat implementation has problems with caching in and out directory info on vfat
and intermittently changes all the modify timestamps by 1, 4 or 5 hours.
This can play havoc if you are trying to keep things synchronized by filetime.
I've decided to have my SD card be ext3
Our volume demon, /system/bin/vold (which is ancient) uses /system/etc/vold.conf to configure automounting.
It presumes that all volumes are vfat.
It seems from a brief look inside that it does handle ext2 and ext3 somehow.
There is also the question of getting it to automount USB drives.
The easiest solution to ext3 on the SD card is to make it non-removable.
First, delete the second section out of vold.conf that relates to the SD card.
Then edit init.rc:
Code:
mkdir /sdcard 0777 system system
...
mount ext3 /dev/block/mmcblk1p1 /sdcard nosuid nodev noatime nodiratime uid=1000,gid=1015,fmask=117,dmask=007
chown system sdcard_rw /sdcard
chmod 0770 /sdcard
If you feel like having 12 partitions on your SD card you can.
That leaves vold only handling the mounting of /media
This exists so that you can serve /media as USB Mass Storage.
You could have /media be a fixed mount by doing what you just did to the SD card.
The only hiccup there would be the Adobe Digital Editions wants to see /media as UMS.
Note: To edit init.rc, download bootutil from the signature, extract, edit and replace init.rc in uRamdisk.
Make sure that you have a backup and a recovery!
Note: All of the above changes to init.rc are wrong.
I can get it to mount in a shell, but not in init.rc
Whoops.

Oops, this thread has been forgotten.
Yes, auto-mounting ext3 SDcards has been solved.

[Q] CM7 boot partition Size

Hello,
Complete noob here and I am not ashamed to admit it. I did create a bootable sd card with CM7 stable on it and the card is partitioned into 4 spaces. The boot space only has a capacity of 117.63 MB, while the 4th partition named CM7 SDCARD has a whopping 28.21GB available.... 112.14MB used..... Im guessing for application. Anyways, I am trying to put books and videos on my NC and there is not enough space that is accessible. Any way to make that boot partition spave larger? Maybe move some of the extra space from the 4th partition? I have EASEUS Partition Master but I have been unable to get it to work..... Any help is greatly appreciated.
I did search for a post like this but did not find any answers which I understood.
Thanks in advance,

What is it that you are trying to do?
Homer

I am trying to put books on my sdcard that I downloaded on my computer for school. When I copy to the directory boot/myfiles/books it says that there is not enough space. So I want to enlarge the size of the boot partition

After you burn the partition image using Win32Image, the size of the boot partition is roughly 117mb. At this point use EASEUS partition to expand the boot partition to the size you want. In my 32gb SD card, I created a 16gb partition. Then I copied CM7.1 and Gapps to the partition, booted NC and CM7.1 was set up in the remaining space, with /data at 5gb and /media at 9gb.

Would you then access the files while booting from the SDcard or internal memory (eMMC)?
If you want to see them when booting from SDcard, don't put them on /boot as you have found out there is not much room. You want them on partition 4. Remember that Windows will not mount partition 4 without some heroic efforts. I use either NookColor UMS (free, see here) or WiFi Explorer Pro (paid, check either Android or Amazon Market).
If you want to see them when booting from eMMC, that is slightly more advanced. You don't have to root, but there is a file on the system on eMMC that needs to be edited to mount partition 4 rather than partition 1. It would take some time to search for it, but someone posted a guide a while back. Search for something like sharing SDcard and/or editing vold.
Homer

Ok...... So I got the boot partition resized to around 20gb and I have copied the books from my hd to the sd card E:\My Files\Books...... Problem is I now cannot acess them when I boot CM7..... Any fix to this or will I have to boot from the eMMC?

Ok....
You're making the easy stuff hard...
You want a large partition that is accessible by CM7 running off the SD and your windows PC. Like Homer said, it is nigh impossible to get windows to mount secondary partitions off of an SD card reader. What he forgot is that CM7 allows you to access partitions 3 and 4 over USB. CM7 can access the boot partition but most apps won't look there and it won't be accessible over USB.
I would recommend that you restart from scratch. Allow verygreens installer to set up the default partitions. Plug your device into your PC and transfer your pdfs to partition 4 that-a-ways. That way you won't have to remove the sd card anytime you want to access your pdf folder.

Even when you plug the CM7 booted NC into your PC, you still need to mount the /sdcard partition to Windows. I find it is easiest to use NookColorUMS on the NC to mount that partition, see above. Otherwise, when you plug into the Windows machine you only get /boot mounted.

Hmm, when I plugged a nook running CM7 from SD card, I get access to /media and /sdcard. I had to move the gapps.zip from /sdcard to /boot manually using a file explorer.

I'm offering an apology to gall and Homer first so pls don't jump on me.
You guys harden a simple issue and confusing the OP.
To OP,
I assume you got a 32GB uSD card, using verygreen's image. You got 117MB on boot.
LEAVE the boot partition ALONE. The only thing you should put there are the ROM (CM7 zip file) and the GApp zip file. NOTHING ELSE. Your music/ebook/video, etc. should NEVER go there. You will place them in the left-over storage created by CM7, normally called CM7SDCARD.
How do you access CM7SDCARD so that you can transfer files over?
The only way is
+ NC on
+ connecting NC to PC (windows)
+ look at the NC notification bar, usb icon should be displayed
+ tap on it, enable usb mass storage (connect to PC for file transferring....)
+ Windows PC should by now recognized the CM7SDCARD and ready for use.
That's the ONLY WAY and the correct way.
If you use that bootable CM7 uSD and plug directly into PC, you only see the boot partition which only 117MB. Again, the boot partition is NOT meant for personal stuff.

What may confuse some people is that when they plug the device into PC then it does not by default auto-mount so you don't get a drive in the PC until you use the USB notification and turn on USB storage.
For non-techie users I normally install the automount USB app from JRTStudio so the drive pops up straight away on the PC and there is no confusion over this point.
The other good reason for using the USB (or alternatively wireless connections like ES File Explorer) is that it reduces taking the SD card in and out and any risk of damaging the socket.

My apologies, I never checked out the USB notification. I sort of ignored it. It seems a handy implementation of the basic functionality of NooKColorUMS.
What is MyNOOKColor though? CM7 SDcard is the one I typically use. Nevermind: it is the eMMC. I never bothered with that one since going to SDcard boot.
