[Q] How Do I Remove An Ext3 Partition From My Sd Card?

I was using my 4gb sd card for apps to sd for my previously-rooted android phone, and had about a 500mb of it partitioned to ext3. I have since unrooted my android phone and put it back to stock, but in doing so, I lost the recovery console that would allow me to unpartition my sd card. Is there a safe program that will recognize the ext3 partition and remove it?

Gparted. You can use a live cd or a VM.

Hi there. I downloaded a free program call minitool partition wizard. Do a google search for it (I can't post links)
It has worked well for me with my SD card partitioning.
Make sure you back up the contents of your SD card before removing the ext 3 partition as it will delete all the contents on it.

could you please elaborate a little as i am a noob. like whats gparted? whats a vm? whats the process of doing what i asked? thanks for the help.

I don't know if Windows recognises it at all but worth a try really. Gparted is a live cd tool that allows you make partitons on a storage device. I think that VM refers to a Virtual Machine, using something like VMWare or VirtualBox.

guys please help. i used these softwares but none of these is showing my ext3 partition in the program window. just a 3.22gb of one partition on phone. the 512mb of ext3 partion is still missing and i dont know where to find it.

Well, since you really don't need the ext3 partition anymore, you could format the whole SD card from windows (do a back-up of the content on the hdd before, though). Then in Windows (I'm guessing you're using windows ), with the phone connected in mass storage mode, right click on My Computer / Manage / click on Disk Management and you should see in the list of the drives your SD card (pay attention to the size). Right click on the 512 MB partition - Delete volume... After that you should create a new partiotion, format it as FAT32... Or you could delete all the partitions of the card and create a new volume.

i did that. in disk management i only see a 3.22gb partition. (i have a 4gb card, so i 512mb is still missing). i cannot find the 512mb ext3 partition anywhere. please can someone help me to find a software or any other method which will be able to detect the ext3 partition as well ?

The partition may be corrupted. You can still try to use Gparted live cd - google for gparted-live-0.7.1-5.zip . It can also be installed on USB flash, check their site for instructions. Restart your PC and boot from the CD or USB flash then check your sd card. If it still doesn't recognize the 512 partition, you might be out of luck.

how could the partition be corrupted because i was using the ext3 partition to install apps when i had root. it was only recently that i have to sell out my htc desire and i unrooted my htc desire. unroot procedure was done successfully but the card is only showing 3.22gb, i-e, 512mb is missing. this may become an issue if the buyer does not want to pay for a 4gb card with only 3.22gb of storage. it should be around 3.5-3.6gb

A partition may become corrupted if you remove the battery from the phone while the system is still running (i.e. writing data on the partition), it is not unheard of. Do try the gparted solution mentioned before, though.

yes buddy i have tried the gparted solution you suggested before. even that is showing only 3.22gb of my sdcard and no mention of the 512mb ext3 partition. i dont know whether i am doing something wrong or what.... ???
Anyway, is there anyway i could recover that corrupt partition? Like can i ROOT my htc desire again and then try to format the ext3 partition from the recovery? i read somewhere there is a way to do that in recovery by giving some commands. and once i have recovered the ext3 partition space then i can UNROOT my htc desire again. DO YOU THINK IF I DO THIS ITS GONNA BE OF ANY USE? Please help me.

This might work since it worked for me. 4GB mysteriously disappeared from my 16GB card and neither Windows or gparted picked it up. The only way I was able to get it back was putting it in my phone and the Android picked it up. I did have to format my whole SD card but nontheless, I got all my space back. Hope this helps and if you have tried this then I can only guess that your SD card is buggered.

um actually, my sdcard IS in the phone this whole time as i dont have any card reader. i am connecting my phone with my pc in hard drive mode.
from within the phone, i have tried to format the sd card many times but the space does not go beyond 3.22gb..

Something seems to have messed the partition up. Have a look around on the web

ok tell me if i root my cellphone again, will it help?
because there is a way to delete the ext3 partition from the recovery.

finally recovered my ext3 partition.
this is what i did.
1) rooted my phone.
2) enter into clockworkmod recovery
3) mount sd-ext (i guess it wasnt mounted that's why no app was recognizing it)
4) now windows was able to recognize the ext3 partition.
5) problem solved.

Use a card reader and MiniTool Partition Wizard.
Delete all partitions on the SD card and create a new one that fills the entire SD

sd card not detected on phone or pc

Hey guys,
A friend of mine gave me his desire to root and flash a rom, while I was partitioning the SD card - everything went well (I used a windows app to create the partitions while the desire was plugged in in USB mode.
All went well until I disconnected it after the process was complete - now the phone nor PC detects the card.
What are my options?
Cheers

You're using a usb card reader on your pc or whilst in your phone (plugged in via cable)?

Using a card reader with the microsd adapter

Use gparted in the reader to see what you can see.

Yup. Try that

OK this is unusual, I managed to boot into recovery and mount the SD and sd-ext without any issue - I even booted into a custom rom I flashed from SD, but I still can't get the phone to detect it when booted.

Like rootSU said, try it with GParted in your pc and see if it can find it. If so, format it all and re-partition it.

OK I managed to get it fixed - seemed like an issue with the partition - I used recovery to mount USB storage (it worked) and I re partitioned it and it is now functioning correctly.
Cheers guys and thanks a lot everyone for their inputs !

What did you repartition with?

I used MiniTool Partition Wizard Home Edition ! very nifty app !

You're very lucky, its an awful app. I feel so strongly about it, I even put it in my signature (incase you missed it).
I bet its because you used minitool that it broke in the first place.

wow, that is rather fine print haha, I hadn't seen that there - I too have a feeling it broke cause of the app, but it did manage to fix it - hopefully I won't have to go through this again - if I have to I'll use gparted - Lesson Learnt !

I'll make it bigger

Way aye, but I dont want it to take over other things

hi. i've faced the same problem too with my galaxy mini.
but, when i mount usb storage it said that "unable to write to umslunfile (no such file or directory)" . and when i format sd card it said "error mounting sd card, skipping format".
my sd card cant detected by any phone or laptop. cant be formatted or mounted. what to do? please help me. there's so much important things there.

Hi there,
Ive been through the same issue just the other day and after read and try lots of things, i had to do something stupid but has worked for me... If you have a digital camera laying around, put your sd card and camera will do its thing..will prompt you asking if you want the sd to be formated... Thats it sd alive and hoping to receive runny rom in my case
hope this works for more people. Take care. Peace.

Damaged SD Card

Hello,
Yesterday while downloading stuff, my phone suddenly sent me a notification that my SD card is broken. I can access everything in Recovery somehow. What I've tried :
- un-mounting & mounting again
- re-flashing
- factory reset
- format in recovery
And everything that I listed above failed. When I plug my card into PC it doesn't open. My whole window is not responding. I've tried mounting it on my older phones (Nokia 2730 & LG KP500), and only Nokia readed my card, but I couldn't do anything because it was password protected. Every possible password I had for my old SD card wasn't the right one. I've already googled but nothing mentioned before helped. When I formatted in recovery it only froze. When I switched ROMs to more "original" one, when I plugged my SD card it was automatically removed. Also my SD card is EMTEC 16 gb Class 4, and just in case I have my old 1 gb sd card lying around.

There is a possibility that your SD card is damaged..........one way of trying to cure it is to somehow try to make it work on your computer and Format it............or just try to format it on the phones that it works on

Going to try format on my old Nokia. But I was thinking, if I can get my SD card to work in Recovery, isn't there anyway to connect my phone to my PC and then try to format?
EDIT: Tried formatting on Nokia 2730 - it was failure. I couldn't because of the password.

In recovery, I should press mount usb right?

Yes

I did as you said and in Partition Wizard it showed me that the whole disk is used, file system was bad disk, and type was logical.
When I tried to format it said "Windows was unable to continue formating".

[Q] Micro SD card HELP!!

Ok So i have 2 micro sd cards one 8GB and one 32GB. I had recently just bought the 32GB one to give myself a good amount of space but unfortunately they both just stopped working all together. Basically one day my GS3 just began rejecting my 32GB card so i attempted to format it on my computer with a usb adapter, i tried both windows and mac os trying a range of programs but it just won't format. I even tried to format it using CWM but it can't mount it. but i don't think its fried because i just got it and it was working fine for like 2 - 3 weeks...so then i put my 8GB card in for 2 days and same thing...can't format or erase or mount on android...i've searched all over the web and need help cuz at this point i feel like my phone is destroying SD cards.
And one last piece on info if it helps I'm running the task AOKP 4.1.1 rom with their latest release and their latest O/C Kernel and clockwork mod touch on an AT&T Galaxy s3

Yeah, this happens to me too. Reboot, let the phone say the card is damaged, open the back case while the phone is on, remove and re-insert sdcard and that should solve your problems.

If you are using windows try using the Command prompt. You will need to select the volume of the sd cards then delete it. I beleive they will become as RAW disks where you will have create them as new disks from disk management.

Open up an admin command prompt, then type 'diskpart' it'll start the utilitiy in command prompt. Then type 'list volume' it'll show volumes 0 through ~8 or so depending on how many you have. Once you know the number that is associated with your sdcard volume, then type 'select volume x' x being the number of your volume. Then type 'delete volume'
After that go into disk management and find your sdcard. It'll say unallocated. Right mouse click and create new simple volume.

Download the SD Card Formatter and try to format your card using that tool; see if that works. I made the mistake of formatting my brand-new SanDisk 64GB microSD card, which worked perfectlyin my Galaxy S III prior to that, and it wouldn't work afterwards. I tried all different methods of formatting & formatting programs to no avail. As soon as I used this program, my card worked like a charm in my phone again!
Good luck!

Micro SD Card Problem

Hey all, does anybody know how to fix micro sd card if it stuck at write protected mode? micro sd adapter wont help :/ phone and pc read's it, but i cant move any files in the micro sd or cant format it..

as i said before, phone and pc wont let me format, it says write protection on sd card

Try using a partition manager to actually remove the partition on the card, create and format a new one.
If that doesn't work its likely a problem with the write circuitry on the card and time to get a new one.

Thanks, for reply, but how can i do that with windows xp?

Look for a free partition manager tool.
Alternatively and better, download and burn an Ubuntu disk. It can be used to boot your pc into Linux, very user friendly and harmless to your Windows installation. That has a built in partition manager which is very powerful

Or download the live linux distro parted magic
partedmagic[dot]com
burn the iso on CD or use unetbootin (just google it) to create a bootable flash drive.
After starting it, open gparted on the desktop
Beware: Don't manipulate partitions starting with sda (this might be your internal hard drive containing windows)

on PC (XP) you can use free tools from:
- Easus (http://www.partition-tool.com/personal.htm)
- Minitool (http://www.partitionwizard.com/free-partition-manager.html)
If you encounter "write protected" card, it may simply be broken.
I had the same issue with my first 64GB SanDisk micro SD and returned it.
Replacement works fine now.

Same solution here:
- burn Knoppix or Ultimate Boot CD (UBCD) on a cd/dvd and boot on restart - format through numerous tools available
- delete partition or try changing drive letter in widows from Device->Manager->Disk Manager
- if write protection continues, try trashing or replacing from vendor
