How do i format my ext2 partition?

Is there a way to format my ext2 partition without reformating the whole SD card? I have some Hero apps on there from when i installed JacHero ROM and i want to remove the app_s folder from my ext2 partition...
Thanks!

use linux, mount sdcard, open gparted, unmount the card, right-click on the card, click resize, make the first partition smaller, format unallocated space to ext2.
use search

Paragon Partition Manager 9
or
adb shell
rm /system/sd/app_s

if u r using windows
i suggest u try Acronis Disk Director Suite. easy and safe.

Partitioning your MicroSD card for Android

I'm using Paragon Partition Manager (9.0 special edition) and an 8GB MicroSD card, and would like to make two partitions, one with the android files, and the other one so that I can put all my other stuff in. Is there a way that I can see my second partition in windows once I connect my phone to my computer, and what type of partition should I make? I can choose between FAT32, NTFS, and Linux ext2 and ext3.
Thanks in advance.

Ideally you are supposed to make 3 partitions:
First partition is the biggest partition (Fat32)
Second partition should be around 256MB
Third partition should also be around 256MB
I also have an 8GB card. However 8GB is really 7.61GB
If i remember correctly what i did was i shrank the sd card from 7.61GB to about 7.10GB...........which created approximately a second partition of 516MB or so.
Then i split that 516 in half so i had 2 partitions of 258MB.
Then i formatted the two 256MB partitions to ext2
***Important***
The fat32 partition (7.10GB) should be the first partition (must be on the left)
Then the other 2 partitions should come after the fat32 partition.
Failure to do this may cause the sd card to not be recognized in windows computer (i think)

Well I got it working with Paragon Partition Manager. I created two ext3 but I had to modify cluster size to 4.
Link2SD wouldn't recognize 2 cluster ext3 and it couldn't mount 8 cluster ext3.

[Q] Failed to setup APP2SD

Hey guys,
I decided to setup my sd card today cause my phone internal memory was constantly running out. I followed the stickies on how to partition the SD using EASEUS. After I partitioned the app2sd partition, i booted up my phone. The phone says there is no sd card. So i rebooted the phone and mount my SD card through recoverymod. I can still see my sd card and files inside of it, but it only has 7GB left instead of 8GB. EASEUS too only detects only one partition of 7GB. Other then mounting the storage through recoverymod's Mounting USB Storage, the sd card cant be mounted anywhere else. Recoverymod shows Error: failed to mount /sdcard for all functions that require the sd card.
Has anyone came across this problem and fixed it ?

It seems that your sdcard is corrupted.
Try to backup all data and reformat all partitions in linux
Windows can't recognize second partition on sdcard & it can sometimes mess up the partition.
Try GParted (google it).

I tried browsing my SD card through GParted ( linux version and boot cd version), and all of them shows only 1 partition of 7gbs. One G is still missing and sd card still fails to work .

Did you make a backup of your sd before creating the sd ext partition
? Should be written in each tutorial concerning sd ext creation.
Otherwise your data is no more.
As already written, windows is not able to read a sd ext partition. its fully right, that your fat32 partition shows only 7gb, the other 1gb is used from the sd ext and not viewable by windows.
...to create a sd-ext very easy go into cwm-advanced-format sd card and chose 1gb ext 0 swap.

Try this :
Backup all data in your micro SD.
Open & boot your computer using Gparted Linux / Parted Magic Linux / any other linux that has GParted / Parted inside its LiveCD
Run Gparted.
Delete all partitions.
Options:
Create sd-ext partition using GParted :
Create 1 fat32 Partition (as Primary) & adjust the size to your liking
Create 1 ext3/ext4 (as Primary...check if your android kernel support ext4) & adjust the size to your liking (usually 1 - 2 GB is enough)
Create sd-ext partition using CW Recovery:
Create fat32 Partition (as Primary...use all space)
Boot HD2 into AD Recovery
Go to Advanced menu
Format & choose sd-ext partition options
Flash your fav. ROM
Notes:
I personally like Parted better than GParted as it's a lot quicker & more advanced options (GParted is only a front-end for Parted).
Parted is for advanced user & TUI.
If you want to try Parted,make sure you read the manual & understand everything related to your actions (open console / terminal & type : man parted)
Use Parted using Root access (open console / terminal & type : sudo parted).
Use it with caution as it can wipe all of your hard drive data !
For more info about Parted try this link :

[Q] Resize ext3 partition on SD card

Have fat32 and ext3 partitions on my SD card, both 4 GB in size. Want to resize them without losing data or having to reinstall anything, using Windows tools only (no Linux!).
If I
1. backup the ext3 partition to my PC hard drive using HDClone,
2. delete existing ext3 partition with MiniTool Partition Wizard,
3. enlarge existing fat32 partition into unallocated space with Partition Wizard,
4. create a new ext3 partition of desired size in the rest of unallocated space with
Partition Wizard,
5. restore the ext3 from backup to the new ext3 partition,
will that work?

hmmm, you have to try ans tell us,
afaik ,, there is no way without backing up data and reformatting .. atleast on WIN

i did a few times it works. but it may be a good idea to flash mgldr after you put sd into phone.

They recommend backing up your data before resizing, it (may) corrupt the stored data

How would i do that:
-backup sd card files on pc.
-make a backup with cwm (also backups sd ext..)
-boot to recovery->advanced->partition sd card: choose your size.
-restore you files from pc to sd
-boot to cwm and restore backup.

Well, I performed the routine on a different sd card now. Created a small ext3 and restored my backups to the appropiate partitions. Said "no" when HDClone asked to "change partition sizes for best compatibility". Seems to have worked beautifully, everythings runs just like before.
Thanks everybody!

I have the same desire: i want to resize my ext partition without losing data.
Many threads have suggested the following:
- backup ext partition (for example though clockwork or in Linux)
- shrink fat partition, delete ext and create new larger ext
- restore backup
I'm sure this routine will work, but it seems rather inefficient.
Therefore my question is: can't i use Minitool Partition Wizard to shrink the fat partition and then enlarge the ext partition all through resizing (and all while the data)?

Can use minitool partition wizard home edition it's free for personal use you can create, resize ,delete any kind of partitions included ext3 and ext4
*Backup your data first

saeid63t, i tried resizing with minitool PW.
While it can successfully resize fat32 partitions (and retain data) it cannot resize or merge ext3 partitions.
Fortunately Gparted can. I downloaded and burned the Gparted bootable live cd. Once booted I resized the ext3 partition while retaining all data of the ext3 partition.
The end result: i enlarger my ext-partition in 10 minutes without restoring or reinstalling any data from recovery and without formating or recreating partitions from scratch again. Gparted all the way for more efficiency!

Write data to ext3

How did you restore data(write data) to new ext3 partition ??
please help....

I couldn't get Mini-Partition or EaseUS to resize the EXT3 partition. I could easily create a larger one, but copying will put the EXT3 partition only into unallocated space, not integrate into an existing EXT3 partition. I even tried reducing the FAT32 partition on my smaller SD card to make room to resize the existing EXT3 partition and the same problem happened.
Does anyone know how to resize an EXT3 partition? You'd think this would be more widely asked about or addressed, given how people will move from smaller to larger SD cards. Yet... once you've got a 2Gb EXT3 partition, you never need to increase it (at least given the current Android ROM's). So, I just moved all of my apps back to the phone, installed the new SD card, then moved them back manually. Thankfully I'm just starting out and didn't have more than a dozen apps to move.

It seems we can use minitool pw to manage sd card partition directly, like resize partition, delete partition, extend partition and copy partititon.

Clockwork Recovery screwed my microSD

I installed the latest SwiftDroid v2.0 RC4.
Before it I wiped everything.
After flashing I entered into Clockwork Recovery. I wiped data again (I had problem with repartitioning so I did it again), and then s*it happened.
I didn't know it will wipe out SD card ! I backuped it, and it wouldn't be problem if it wiped it.
The problem is, it erased ext2 partition, swap partition, and heavily crippled main FAT32 partition. Now my microSD card has only 1,86 GB, and it has 4 GB capacity! The half capacity is gone ! I checked in MiniTool Partition Wizard Home Edition, and couldn't beleive. OK, maybe MiniTool is wrong. I booted Parted Magic, and the same s*it !
Is there any way o claim back lost 2 GB of space, or should I go and buy new microSD?

In MiniTool or parted magic, delete all of the partitions on your SDCard. Then create a fat32 partition from the unallocated space. Note: You WILL lose all data from the SDCard when doing this. Then try re-partitioning using clockwork. Also, you don't need the ext2 partition if you are planning to use apps2sd in swiftdroid, as you can use Android's built in one that doesn't require a seperate SDCard partition.

I forgot to type I did it.
I deleted partition (it wasn't FAT32, it was FAT16 after CR messed up!), and microSD has only 1,86 GB.
Entered in Clockwork Recovery, and it can't mount microSD card.
Frustrating.

You can try something but it requires Ubuntu installed or livecd (Not sure if other distros have the same utility)
Put your SDCard into a card reader (or you can try and mount it using USB) and then search Disk Utility from the Unity menu and open it (or in the standard user interface go to System>Administration>Disk Utility)
Click on your SDCard in the sidebar, and then Choose 'Format Drive' (at the top) Choose Master Boot Record and then click ok. Then format the SDCard as FAT32.
